FIELD: information technology. ^ SUBSTANCE: system for creating compact description of digital materials has a reception module which can receive digital material, a segmentation module which can breakdown the said material into a set regions, a computation module which can calculate feature vectors for each region from the said set, where the feature vectors are calculated based on matrix invariance which include singular decomposition, an output module which can generate an output result using a combination of calculated feature vectors, where the output result forms a vector of hash-values for the said digital material, where the vector of hash-values is compact presentation of the digital material such that, digital material is identified based on the said compact presentation. ^ EFFECT: broader functionalities. ^ 9 cl, 3 dwg |
