I was just thinking about this the other day. I think content-based
image search is one of the Next Big Things. Cameras are so ubquitous
now (for better or worse), but having to rely on metadata to give
meaning to images requires lots of effort up front.
It
will be interesting if we ever get to a stage where we can just search
for a random object (or person) in a database of photos. Then you could
take pictures of everything with an always-on camera and if you need to
find where you put your car keys, just do a search. |

I forgot one more, where specific faces were automatically retrieved from feature-length movies and Fawlty Towers:
Automatic Face Recognition for Film Character Retrieval in Feature-Length Films [cam.ac.uk] (Arandjelovic & Zisserman, 2005)
The
objective of this work is to recognize all the frontal faces of a
character in the closed world of a movie or situation comedy, given a
small number of query faces. This is challenging because faces in a
feature-length film are relatively uncontrolled with a wide variability
of scale, pose, illumination, and expressions, and also may be
partially occluded. We develop a recognition method based on a cascade
of processing steps that normalize for the effects of the changing
imaging environment. In particular there are three areas of novelty:
(i) we suppress the background surrounding the face, enabling the
maximum area of the face to be retained for recognition rather than a
subset; (ii) we include a pose refinement step to optimize the
registration between the test image and face exemplar; and (iii) we use
robust distance to a sub-space to allow for partial occlusion and
expression change. The method is applied and evaluated on several
feature length films. It is demonstrated that high recall rates (over
92%) can be achieved whilst maintaining good precision (over 93%).

I just did a quick search based on this
[designer.am] image of a Qantas logo (that's the main Australian
airline, in case you're wondering...) It's red, with a white kangaroo
in the middle. My theoretical aim was to find photos of Qantas planes.
What I got was an awful lot of red planes - some of which were
actually Qantas planes, but I think more by coincidence (i.e., they're
red) than design. Many images had nothing to do with Qantas, or even a
red plane - they simply had a lot of red in the image.
This is impressive in some ways, but in others it seems like
it's simply looking for similar patches of colour. I haven't done
enough testing to see what happens if,say, I gave it a half red half
green image.
Interesting, but not ready for public consumption just yet. A
bit like A.L.I.C.E. the artifial intelligence system actually - neat,

Programs like GQview (unix/linux) offer functions to search for similar images, mainly used to find duplicates.
It's
not quite "put in an image and find me all the similar ones" but the
underlying technology is the same, usually creating some kind of
"signature" of each image and then comparing the signatures to find
others visually similar.

The Mona Lisa (famous and out of copyright) is often plagarized in
whole or in part as part of commercial or satiric artistic works. These
types of visual database engines have frequently been explained to me
as being able to input the Mona Lisa and get a list of images that used
the entirety of the image or just a part (such as the highly-praised
subtle smile).
The big problem to me is specifying input. I know the "look" of the
Mona Lisa's smile, but even with the best pen input methods I'd never
be able to mimic DaVinci's subtle emotion of the smile; my hands just
aren't capable of doing so. Using photos of the painting could simplify
this, but this almost assumes that I'm only looking for the parody's
and commercial exploiters of the image rather than the image itself
(after all, I have the image to start with). And it raises the further
issue that many photographic reproductions of the Mona Lisa that I can
get my hands on are still under copyright and I'd be doing something
legally questionable with an image long in the public domain.
Add to this the "infinite number of monkeys" issue where
legally litigious companies will use technologies like this to scan the
internet for litigation targets. Imagine Disney using a cell of Rafiki
from the Lion King to find legally similar images that were created
after the Lion King was released even if they were only superficially
similar. Now do this for all movies back to Snow White or Steamboat
WIlly and you could get to be a real visual mob boss with ownership (or
at least threat of litigation) over huge libraries of works that
weren't even created to intentionally violate Disney "Intellectual
Property".
My need for this technology is small considering the input
problems I'd have with my artistic abilities, while the litigation
nightmare from large databases of "similar" visual data would seem to
be more bothersome than helpful. I rather hope these visual search and
categorizing methods don't catch on.

However, he put forth the concept of replacing the bit as the common

A.net is very stringent on the photos they accept. You can submit
hundreds of photos, and get rejected for such things as 'badmotive' (a
runway sign blocking a single tire), very mildly soft focus, and lots
of other pretty anal things (IMHO). So while the image count they are dealing with is high, the obvious resulting similarity among images will result in a high number of matches. Now,
do this for something like Google Images or PBase or collections
spanning infinite numbers of subjects and image sizes, then I'll get
excited. No, I've never had a rejection from A.net, I've never
submitted there. Two minutes in their forum will tell you how anal
their 'screeners' are, for whatever reason. It's just freakin' pictures

I've tried two different images of airplanes; one of a bright red
flying car on bright green grass and one of SpaceShip One against a
deep blue sky. Both times, the results looked surprisingly like my
query images in color composition only. Red planes on grass and white
planes against a blue sky. Inauspicious start.
Next experiment: I took a picture of a highly distinctive plane, a
harrier, climbing at a steep angle and viewed in profile. I got, in
return, a list of passenger jets, and even a helicopter. Hardly
surprisingly, all of the result pictures had the same bluish white sky
as my original image. That was literally the only similarity.
According to the introduction on the search page the heuristics used compares colors, contrast and shapes in the images themselves.
I saw no correlation whatsoever between shapes, and any correlation in
contrast seems to be to be the result of the search engine simply
looking for images that contain the same colors in a similar ratio to
the original. In short, nothing to see here, move along.
On the other hand, one of the projects listed under the Penn State University link looks fairly fascinating. The Riemann a-LIP project
[psu.edu] (automatic linguistic indexing of pictures) doesn't allow
user input of images, unfortunately, but it does show some fairly
fascinating attempts at verbally qualifying image data. For example, it
describes a blue and orange mandelbrot as pattern agate shimer abstract scene, and a sunset over a lake as Berlin Devon Namibia landscape lake scene. Okay, it may still need some work, but it sure beats the hell out of the "find the same color airplane engine".

Given that it apparently has trouble telling the difference between an SR-71, a Chinook helicopter and JFK airport's formerly-TWA terminal [airliners.net], among other things... I think it could use some tweaking.
Of course, given the usual course of things, it will instead be deployed at JFK's formerly-TWA terminal, assigned facial recognition tasks, and immediately declare everyone to be among the 10-most-wanted terrorists. I can't wait.

How about just searching for an identical image? (Score:1)

This is great and all, but I would love for a way to upload a graphic
file to a search engine and have it report back any identical (or
nearly identical.. perhaps a "threshold" setting) copies on the web.
This would be useful to me as a photographer to see if anyone out there is using my photos.

About a year or so ago, I and three other Masters students worked on a similar project at the University of Southampton.
I've
not RTFA (not had the time), but our approach was to split the images
into segments (based on colour and texture) which were assumed to be
objects. The segments would then be analyzed for various feature
vectors, such as shape, texture, colour etc. These vectors would then
be added into a database of numbers, and finally the segments grouped,
giving a collection of classified sections which (hopefully) represent
similar objects.
From related metadata such as keywords, you
could then hope to build up an idea of what keyword matches which
section. You could also come up with a relevance between two images,
and thus search for similar images.
We didn't have enough time to make it bulletproof by any means, but our limited results were very promising.
Sorry I can't find the paper, but we've got some screenshots of the application here [soton.ac.uk] and here [soton.ac.uk] (you can see false colouring applied to the original image to display the segments)

Ridiculous.
Image search will kinda work for airplanes in this database,as there
are a very limited set of airplane model numbers, which are going to be
attached to each photo.
But if the database didnt have these text clues the image
search is going to be unlikely to see the similarity between an 747 in
the air, as seen from the ground, with a head-on view of a 747, or one
at the gate, or one in a hangar, or one in twilight, or one of a
different color.
Maybe it could be done by outsourcing the task to India?

I was trying this out a bit, and have to admit that it's cool that something like this exists at all.
However,
I think it would be better if it were able to realize what the
'background' was and filter it out. (Though I couldn't begin to guess
how you'd do this.)
For example, I searched for this image [airliners.net]. Many of the results
[airliners.net] are of something completely different, such as a white
jet. Which is nothing like a camo helicopter. But the sky and the
ground are pretty similar, and I think that's how it's matching.
It's
incredible that we got this far, but I think there's still a long ways
to go before it's at the stage where you put in an image, and are awed
at how quickly it works.
Also note that I'd tend to think this
would exponentially more difficult than searching HTML files, so it
might be much more expensive to implement large-scale. |

CBIR is the same problem as AI (Score:2)
by HuguesT (84078)

In general image understanding is equivalent to general AI. We won't
get a CBIR system that works well before we get an AI that works and
vice versa, because people expect to be able to match the *content* of
the image they submit as template and not the general appearance of the
image. The problem is then too unspecified.
Even
in the restricted context of aeroplanes this is not a trivial problem.
Someone in the list of replies submitted an image of a warthog (A-10)
and got nonsensical results. Somehow the CBIR system would need to be
able to infer a model of the A-10 from a given random 2D projection,
and match it to the other 2D projections of the same A-10 model that
they do have in the DB. This doesn't sound impossible but it is hard,
and I suspect the Penn State people didn't do that. Instead they are
probably matching on colour, texture, general appearance, etc.
This
is not to say that CBIR is not a nice problem to apply new image
processing/image analysis algorithms to, which are developed all the
time. |

Video loops etc (Score:1)

When this becomes a little more refined, it will be nice to apply to
frames of video to assist in creating video loops. For example, you
mount a camera near the coast, and get 3 hours of footage of the waves
crashing against the rocks. You want to make a nice loop of that, which
can play indefinitely, but you want to avoid that 'jump' that always
seems to occur. Find small sections of the movie where say...10 frames
in a row are similar to 10 other frames...
It'll take out a lot of the usual pain. |

Because it still has problems - you'll note that the pictures seem to
be compared simply based on color similarity. That's the same thing imgSeek
[python-hosting.com] does (a great program for sorting and searching
your photos) on photo searches. It works wonderfully if you're
searching a very limited picture subset (say, airplanes), but if you
search a wide variety of pictures, the results can be quite amusing.

Google actually did
take this technology and try it. The first version of their image
search had a "find similar" link next to every image. These tended to
work okay at first (they weren't great, but you usually got enough
photos back that you could visually scan them and find something of
interest that was related to the original image). After a few months,
for some reason, the "find similar" links started returning
increasingly nonsensical results. After it degenerated to the point of
near uselessness, they took the "find similar" link away from the image
search results. I expected it to turn up again once they got the kinks
worked out, but apparently they just decided to stop working on it. |
