This paper presents a study on human detection using the multi-scale covariance descriptor (MSCOV) proposed in a previous work [1] in which we showed the performance of this descriptor for human re-identification. In this work, we evaluate its performance in human detection. We propose a fast tree based method for multi-scale features covariance computation. This method considerably speed up the image scan process for fast object detection. Furthermore, we experimentally evaluate the human detection performance using region covariance descriptor (COV), multi-scale covariance descriptor (MSCOV) and histogram of oriented gradients (HOG). In term of classifier, we consider the popular Support Vector Machines (SVM). The experiments are performed on both benchmarking datasets INRIA and MIT CBCL. Experiments on both datasets show the high detection performance of the MSCOV based detector.
