- Abstract:
-
Target re-identification via cross-camera is a challenging problem in the field of multi-camera surveillance. How to get a more accurate distance measurement algorithm is the key to solve this difficult problem. So, in this paper, we established a new measurement algorithm without training based on extracting more excellent features to do target re-identification, which is optimized diffusion distance. On the basis of high-dimensional diffusion distance, Gaussian pyramid image sampling and weight optimization are added to improve the discrimination of similar space vectors and increase computational efficiency. The final similarity measure function is established by the second optimization of the high-dimensional diffusion distance. At last, we do numerous target re-identification experiments based on databases VIPeR and ETHZ. The matching rate of rank first image can reach 50.5%. The experimental results show that the algorithm proposed in this paper has good performance.
