Title: The design and application of visual target detection and tracking system
Abstract
Moving object detection is a hot fields in today's computer science research, closely linked with many fields, such as military and civilian, areas of science and technology, mainly include image processing, computer, pattern recognition, etc. As a has a perfect theory and implementation method of discipline, target tracking research has never stopped, lots of new algorithm is implemented, in order to satisfy the demands of increasingly large and perse 。This article will elaborate the basic steps of target detection based on visual tracking technology and implementation method of each step and achieve a complete identification tracking system. Implemented system, the detection based on background subtraction technology, using the median filtering method to extract the background, the target contour way to track and achieve the target trajectory. Paper mainly includes target detection technology is introduced, the background extraction technology is introduced, target tracking technique is introduced, and the realization of the complete test tracking system and analysis.
Keywords：computer vision ；target detection ；target track
