Don't usually do,If the code inside this, apart from grammar, isn't that right, this comparison is an object, the object of comparison is the comparison of reference address, so if not refer to the same address is false, this determination
If it is on the comparison of image data, then for the two pictures, in theory should be a pixel by comparison, there are two problems: 1, 2, compare the amount of data is too big for the lossy compression of data is out there must be some differences, such as a BMP and a JPG you look, more is different,
Suggested comparative method:
1, if confirmed two image data is completely consistent, then extracts the two data respectively, such as MD5 results and compare
2, if it is after the lossy compression of data comparison, to a certain tolerance coefficient of pixels compared again,
