error: (-215) size,width>0 88 size,height>0 in function imshow

这个错误通常是因为在调用`cv2.imshow`函数时传入的图像变量的宽度或高度为零。这可能是由于截取图像后导致其中一个尺寸变为零的原因。解决这个问题的方法是在传给`cv2.imshow`之前对图像进行检查，确保它们的尺寸都大于零。你可以打印出截取图像的宽度和高度，检查是否有其中一个为零。如果是的话，你可以对图像进行处理，确保尺寸不为零，然后再传给`cv2.imshow`函数。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
