import numpy as np import cv2

img = cv2.imread("mud.jpeg",cv2.IMREAD_COLOR)

cv2.imshow("bhatnagar",img) cv2.waitKey(5)

This is the error I am getting: I have even tried by giving the path of the image which could also be done if in case the file is not in the working directory.

OpenCV Error: Assertion failed (size.width>0 && size.height>0) in cv::imshow, file C:\projects\opencv-python\opencv\modules\highgui\src\window.cpp, line 325

cv2.imshow("bhatnagar",img) cv2.error: C:\projects\opencv-python\opencv\modules\highgui\src\window.cpp:325: error: (-215) size.width>0 && size.height>0 in function cv::imshow

it did not find the image, or it is not a jpg, but a mislabelled gif.

anyway, you have to check if image!=None: before proceeding with imshow() or the like.

@lucifer97, the problem is simply, that python ppl NEVER check the outcome of imread() or cap.read() so, if something goes wrong there, it errors in the NEXT line, because of an invalid image.

so, same for the webcam: CHECK !
