hough-change
- 利用opencv对图像进行哈夫变换,Hough变换利用图像空间和Hough参数空间的点-线对偶性,把图像空间中的检测问题转换到参数空间。通过在参数空间里进行简单的累加统计,然后在Hough参数空间寻找累加器峰值的方法检测直线。-Opencv use the Hough transform to the image, Hough transformation point- line Duality image space and Hough parameter space to the image
TwoStageFilter
- 利用opencv实现烟雾检测,利用的特征是:在[0.625Hz,2.5Hz]带宽的频率范围内,监 测图像序列的灰度值通过一个二阶的滤波器后,子信号的频率值的变化,观察其峰峰值的个数,当峰值个数超过2次的时候即可判定为烟雾点-Smoke detection using opencv realized, is characterized by the use: In the [0.625Hz, 2.5Hz] bandwidth, frequency range, the gray value o
OpenCVfaceHead
- OpenCv用于摄像系统人头统计,VISUAL C++.0 MFC版峰值计数1.0,加高速方向检测统计(OpenCv for camera system head count, VISUAL, C++.0, MFC version, peak count 1, plus high-speed direction detection statistics)
