Abstract: A method for precise positioning of the eyes. Eyes positioning is a lot of face detection algorithm is the key step. In access to eye window, you can use projection methods to locate the eyes. A hybrid projection function that combines the integral projection function and variance projection function, can reflect the image in one direction, the integrated mean and variance changes. The experimental results show that the hybrid projection function can be quite accurately determine the location of the eye center. (2011-06-15, PDF, 213KB, 下载14次)
基于图像识别算法的森林防火系统设计
传统的森林火灾监测技术包括人工护林监测、飞机航测、卫星监测等。本文提出一种基于普通CCD 摄像头和瞭望塔上现有
的短波无线通信设备的森林防火监测系统, 根据实时图像与参考图像的差分及小波分解结果, 当有异常情况发生时, 提取出火焰及
烟雾区域, 判断提取区域是否具有烟雾和火焰的动态特征。若判定发生火灾, 即将压缩后的图像通过短波通信设备传回指挥中心。
Image recognition algorithm based on forest fire prevention system designed to monitor forest fires, traditional technologies such as artificial forest monitoring, aircraft and aerial survey, satellite monitoring. This paper presents a general CCD-based camera and observation tower on the existing short-wave wireless communications equipment, forest fire monitoring system, based on real-time image and reference image and the wavelet decomposition of the difference a result, when there are unusual circumstances arise, to extract the flame and smoke region, to determine whether the extraction of regional dynamics of smoke and flame characteristics. Determine if the fire broke out soon after the image compression short-wave communications equipment through the center return. (2009-04-10, PDF, 202KB, 下载110次)
