Web11 de fev. de 2016 · Hi, I'm trying to compute the moments of the pixels found in a connected component of a gray scale image. I have in a matrix cv::Mat contMat a gray scale image. After thresholding it to another matrix binImg, I found its connected components with cv::connectedComponents(binImg, lblImg, 8); I went ahead and created a … WebImage Moments. 我们可以在OpenCV中使用矩来找到blob的中心。但首先,我们应该知道图像时刻到底是什么。图像矩是图像像素强度的一种特殊的加权平均值,它可以帮助我们发现图像的一些特定性质,如半径、面积、质心等。
WebOne of the most exciting features in OpenCV 4.5.1 is BEBLID (Boosted Efficient Binary Local Image Descriptor), a new descriptor able to increase the image matching accuracy while reducing the execution time!This post is going to show you an example of how this magic can be done.
