APPARATUS AND METHOD FOR SEMANTIC MATCHING BASED ON MATCHING RELIABILITY

摘要

The present invention extracts features from each of a pair of applied input images according to a pattern estimation method learned in advance to generate a feature map of a phase comprising a plurality of feature vectors, and a feature vector between the generated pair of feature maps. A correlation volume acquisition unit that obtains a correlation volume by analyzing the correlation according to the degree of similarity between correlations, calculates the reliability based on the mutual consistency between correlations, which are elements of the correlation volume, and calculates the reliability of the initial confidence volume according to the pre-learned pattern estimation method. A reliability volume acquisition unit that estimates and reinforces a pattern and obtains a refinement reliability volume by filtering the reinforced reliability with a predetermined reference value. A displacement map is obtained by calculation, and the correlation is compensated so that an important area of the correlation volume is emphasized using a guide map acquisition unit that generates a guide map by propagating the displacement of the displacement map to the surrounding area in a predetermined manner, and the guide map. , including a matching unit that obtains a semantic matching map by estimating the pattern of the refined correlation volume compensated for correlation according to a pre-learned pattern estimation method, and is guided based on the confidence volume to significantly improve the semantic matching accuracy A matching apparatus and method may be provided.
