Comparing two images, or an image and a model, is the fundamental operation for any retrieval systems. The similarity matching of two images can reside in the hierarchical levels from pixel-by-pixel level, feature space level, object level , and semantic level. In most systems of interest, a simple pixel-by-pixel comparison will not suffice: the difference that we determine must bear some corre...

Therefore those should be a part of every kind of PC working-learning – of course in a hidden, spontaneous way. And it is not important whether the students master the basics of algorithms through the work with a text editor, internet or multimedia. The Imagine Logo environ...
