Spatial Pyramid-Based Statistical Features for Person Re-Identification: A Comprehensive Evaluation

Person re-identification (Re-Id) across nonoverlapping camera views is one of challenging problems in surveillance video analysis. The difficulties in person Re-Id mainly come from the large appearance variations caused by camera view angle, human pose, illumination, and occlusion. Recently, extensive efforts have been cast into addressing this problem by developing invariant features or discriminative distance metrics. However, there is still a...
