Person Re-Identification Using Color Enhancing Feature

In this paper, we propose a novel feature descriptor for person re-identification without personal information. It is called Water-Drop Render Box (WDRB). The WDRB method is calculated by three steps with target color and its histogram: registration of target color, transformation of distance map, and enhancement of color using target histogram. In order to calculate WDRB, person's top-view images of entering and leaving the room are captured. This is achieved by constructing a bird's-eye view camera system. The person re-identification is carried out by estimating Bhattacharyya distance between database (entering/leaving room person) image and input (entering/leaving room person) image. Finally, the effectiveness of our WDRB descriptor will be demonstrated through several person re-identification experiments. According to the experimental results, it indicates that the WDRB method can be also used for object re-identification.
