Sekundarni povzetek: | With the digitalization of capturing images, the amount of images drasti- cally increased and searching through a collection of images became very hard. This dissertation deals with querying a collection of images based on a reference image. We use a modern approach based on features obtained from a deep model based on a convolutional neural network. Such features are not sparse and we cannot build inverted indexes with them. In our approach we use hierarchical clustering with a conditional density tree for querying. We build a prototype of an image search service with the tree structure which is able to responsively serve multiple users at the same time. We test the solution against a brute force approach and find that the suggested method is more suited for large collections of images, as it consumes less memory and needs less time for queries. |
