WebAug 27, 2015 · 1、角点检测函数和参数说明 cvGoodFeaturesToTrack()函数主要是处理IplImage数据格式的图像,而goodFeaturesToTrack()函数主要是处理Mat数据格式的图像。参数quality_level :特征值最大值最小值乘法因子;参数minDistance:角点之间最小距离;均对图像中harris角点检测的个数有影响。 WebJun 23, 1994 · No feature-based vision system can work unless good features can be identified and tracked from frame to frame. Although tracking itself is by and large a solved problem, selecting features that can be tracked well and correspond to physical points in the world is still hard. We propose a feature selection criterion that is optimal by construction …
