Moving object detection is often one of the most basic and important stages in computer vision applications. In this paper, a novel background model is proposed to extract moving foreground objects from videos that may contain different kinds of disturbance such as illumination changes, camera parameter variations, noises and dynamic backgrounds, etc. For each frame, a local frequency response map...
For application researches of the detection for the gas signal source, a method for orientation estimation of the gas signal source in the two-dimensional space and its algorithm are presented in the paper. In the method, a mode of dual-line gas sensor array is applied to sample the signals of the gas concentration in real time, and the time delay estimation, an approach of the signal processing,...
