The error message input error message " cv2.error: OpenCV(4.4.0) ... error: (-215:Assertion failed) !_src.empty() "
in function 'cv::cvtColor' indicates that there's an issue with the input image (_src). The error is specifically pointing out that the image is empty or invalid.
SOLUTION
Try with an image of a different extension.
Example, if your input image has .png extension, try another image with the extension .jpgCheck if the Image File Exists:
Ensure that the image file you are trying to read and process with OpenCV exists in the specified path.Check error with a simple print statement.
Example in Python:
image = cv2.imread('your_image_path.jpg')
if image is None:
print("Error: Could not read the image.")
else:
# Continue with further processing...
- Check Image Content. It's also possible that the image file is corrupted or in a format that OpenCV cannot handle. Try opening the image with a different viewer to verify its integrity.
