| Popis: | The field of person re-identification remains a challenging topic in video surveillance and public security because it is facing many problems related to the variations of the position, background and brightness scenes. In order to minimize the impact of those variations, we introduce in this work a multi-stream re-identification system based on the fusion of local and global features. The proposed system uses first a body partition segmentation network (SEG-CNN) to segment three different body regions (the whole body part, the middle and the down body parts) that will represent local features. While the original image will be used to extract global features. Second, a multi-stream fusion framework is performed to fuse the outputs of the individual streams and generate the final predictions. We experimentally prove that the multi-stream combination method improves the recognition rates and provides better results than classic fusion methods. In the rank-1/mAP, the improvement is of \(7,24 \%\)/9, 5 for the Market-1501 benchmark dataset. |
