Compare Images.

[FISH786]

Can someone help. I am not sure but I think i read about this before. I can't find it when I need it. I am looking for anything that will help me compare 2 images of diferent sizes using VC++. The following only tell me the sizes are different. However I already know that they are different.

BYTE image1[ImageSize];
BYTE image2[ImageSize];
// load the images not shown

if( memcmp(image1,image2,sizeof(image1)) == 0)
// they are the same
else
// they are different

Thanks a million

Hi Fish, The real question is how much accuracy do you require. If I wanted a quick and dirty image compare I would probably create a histogram of the colors[^] in both images. If you need greater accuracy then maybe you could use a library specifically designed for computer vision. Integrating Vision Toolkit[^] VLFeat[^] Best Wishes, -David Delaune

Like Randor said, it depends on what you are looking for, but http://www.codeproject.com/Messages/1957223/Re-Extending-this-Idea.aspx[^] may be of some help.
