||In this talk, I will present my master thesis, which I have done at Comenius University in Slovakia.
The semantic gap between the digital image representation and the userís image understanding is still a big problem. In my work I tried to reduce this semantic gap in a ﬁeld of natural images. My master thesis proposes a method for semantic categorization and retrieval of natural scene images with and without people. These are typical holiday pictures from hiking outdoors. The approach comprises of three stages. At the end the results obtained by two types of classifiers are validated.
