Master’s internship (M2) / XLIM - Université de Poitiers, France 
Title: Detection and classification of moving objects from compressed surveillance videos based on Machine learning
keyword: Moving objects detection, Machine learning, Deep learning, Compressed-domain, Utility.
March - August (Answers expected ASAP because of the security clearance).

Project context

Automated artificial vision technologies are becoming widely adopted for monitoring and surveillance applica- tions to reduce the need for physical resources and human intervention. One way to help police investigators during the monitoring task is to perform a preselection of sequences having the best characteristics for de- tection, recognition and identification (DRI) tasks. This selection relies on several criteria related to visual quality, camera features, embedded metadata, usefulness of the content for DRI, and so on.


The aim of this internship is to study moving object detection and classification from compressed surveillance videos. For compressed domain video content analysis, the features, such as motion vectors and block coding modes and DCT coefficients using a partially decoded data, are extracted directly from the bitstream. The major advantage of compressed-domain approaches lies in the low computational complexity since the full- scale decoding and reconstruction of pixels are skipped. Objects present in the scene will be classified using convolutional networks and deep learning [1, 2]. Based on this classification, the task of utility estimation will be conducted in order to accelerate the negative filtering of the video database.
