基于视频的手写数字识别

摘要

随着计算机技术的不断发展，视频跟踪技术越来越成为计算机领域中研究的热点。视频跟踪技术的研究涉及范围很多，包括视频图像处理、模式识别以及人工智能等，具有较强的研究价值。手势检测识别技术作为一种基于计算机视觉的新型人机交互方式，是其中备受瞩目的研究和应用技术之一。文章采用一种简单高效的颜色直方图对目标(红色手指)进行主色定位，并在图像序列中进行目标区域提取，得到运动轨迹，进行手写数字识别。最后利用八段视频验证了该方法的简单高效，并能成功进行实时跟踪与识别。%With the continuous development of computer technology,video tracking technology has become a hot re-search field of computer.Study of video tracking has strong research value,including video and image processing,pattern recognition and artificial intelligence.As a new type of human-computer interaction based on computer vision,gesture detec-tion and identification technology are the high-profile research and applied technology.This article positioned the target (red fingers)with the main color by using a simple and efficient color histogram,extracted the target area in the image se-quence to get the motion traj ectory,and identified handwritten numeral.Finally,experiment on eight videos shows that this method is simple and efficient.With this method,real-time tracking and gesture recognition are successful.
