OpenCV Quick Guide - OpenCV is a cross-platform library using which we can develop real-time computer vision applications. It mainly focuses on image processing, video capture and analysis including features like face detection and object detection.
注意2:绘制图像是在原图上绘制,这里我们写的是专门在原图上绘制,后面draw轮廓的话,可能需要 img.copy()了。不然我们的原图会存在画的轮廓。 1.2 绘制矩阵 在OpenCV中,绘制直线使用的函数为 rectangel() ,其函数原型如下: 1 2 3 4 5 6 7 8 9
函数原型:voidfindContours( InputOutputArrayimage, OutputArrayOfArrayscontours, OutputArrayhierarchy, intmode, intmethod, Pointoffset=Point() ) image:8位单通道图像作为输入,0像素值保留为 0,非零像素被当成 1,即输入图像被看成二值的。可以使用compare(),inRange(),threshold(),adaptiveThreshold(),Canny()...
image – Destination image. contours – All the input contours. Each contour is stored as a point vector. contourIdx – Parameter indicating a contour to draw. If it is negative, all the contours are drawn. color – Color of the contours. ...

论文原话是:Finally, the antepenultimate picture of each row is downsampled - see the blue arrow. This starts another row of convolutions. we repeat this process until the picture are too small to proceed.(By the way, each row is usually called an octave since the sampling rate is decreased...
