Need help with image comparison.

[Yancie]

I am looking to build a program that takes an image and compares it to a folder of images and finds a smiliar comparison. Something like this....

blackandwhiteimage.jpg Compare To \images\directory of color images

Result:

blackandwhiteimage.jpg result suggetions Perfect.jpg
Pretty Good.jpg
Might be.jpg

but displaying the the images.

Just need a good start on this.

Thanks!

That wasn't quite what I was looking for.

I have a lot of black and white photos that need to be compared to a lot of color photos and have suggestions for matches spit out.

Seems like project I pointed you to which is all about comparing two images would have been a pretty good start.
You came back with "not quite what I was looking for" in less than 10 minutes from when I posted that. There is no way you scrubbed through the project code to see if there was anything useful in it.

It seems to me that if the project mentioned already does a color to color comparrison then it should be a good base for your bw to color comparrison need. Just load an image, make a bw version in memory, then use this same technique to compare them. [repeat]

I can't speak to the quality of the algorithm for your situation, as you might have to convert grayscale (I assume you mean this and not pure black and white) to faux colors to get a good comparison. I'm betting that under the hood it's not too much different than the one tlhintoq recommended, however.
