img = cv2.imread('your_image.jpg') res =cv2.resize(img, dsize=(54, 140), interpolation=cv2.INTER_CUBIC) img因此,这是一个包含原始图像res的 numpy 数组,而一个包含调整大小的图像的 numpy 数组。一个重要的方面是interpolation参数:有几种方法可以调整图像大小。特别是因为你缩小图像,而原图像的大小是...
NonUniformImage可用於顯示帶有插值的實際 bin 邊: >>>ax = fig.add_subplot(133, title='NonUniformImage: interpolated',...aspect='equal', xlim=xedges[[0,-1]], ylim=yedges[[0,-1]])>>>im = NonUniformImage(ax, interpolation='bilinear')>>>xcenters = (xedges[:-1] + xedges[1:])...
