There are so many graphics stored in graphic format. Graphs were generated using the program. However, due to the fact that the programmer making the software to create graphs, could be wrong, that an independent programmer has written his own program and as well generated graphics. Now we have to match them. But I don't want to spoil the vision and would love to automate this process. Therefore, we need a ready-made program that will find the "10 differences" of 2 images. If there are such programs — are asked to provide at least the name, and even better a link to download.
