Compared two images that look alike

is there a way to compare to images that will alike. There might be a subtle difference between size. Color wouldn't be a factor since their black-and-white. The basic size of the images also very close, dimension. The only difference would be the content of the image. The actual image is a document or a record. In most cases a file name does group the images. I don't know how I do it but it seems there is some kind of a difference when using duplicate MD 5 checksum. I have asked for help in the past regards to this. But I'm still out there trying to figure this one out.

If you do a web search on Image Comparison Software you may get some pointers. For example, there is some discussion of possible tools here.

I found something immediately on that way which I'm evaluating. Unfortunately you have by the product first to really test it, which I will be doing later today. If this works somewhat at all it will be a great help. If it does half of what it says it's unbelievable.

If you have two files and there is any difference between their contents, no matter how subtle, then their MD5 checksums will be completely different.

MD5 is useful for finding identical files but it won't help you find files which are only similar but not quite the same.

I use this program and it is free. Works pretty well and can create numerous profiles too. It is compatible with Win 7 64 bit OS. I hope you find this useful.

That's what I thought. I have to dig into it a bit. I thought it worked for me in the past, MD5.

When comparing to images of text documents, building permits. Address information will be different but everything else is pretty much the same. I have any directories that hold over thousand images. I'm trying to find the images that are close to equal. Looking at a thousand images I might have 75 200 duplication's. Be able to find them automatically would be great. You still think MD 5 is my best bet.
