OpenCV resize fails on large image with “error: (-215) ssize.area() > 0 in function cv::resize”

Question

I\'m using OpenCV 3.0.0 and Python 3.4.3 to process a very large RGB image (107162,79553,3). While I\'m trying to resize it using the following code:

import

You can manually place a check in your code. Like this -

    if result != []:
        for face in result:
            bounding_box = face['box']
            x, y, w, h = bounding_box[0], bounding_box[1], bounding_box[2], bounding_box[3]
            rect_face = cv2.rectangle(frame, (x, y), (x+w, y+h), (46, 204, 113), 2)
            face = rgb[y:y+h, x:x+w]

            #CHECK FACE SIZE (EXIST OR NOT)
            if face.shape[0]*face.shape[1] > 0:

                predicted_name, class_probability = face_recognition(face)

                print("Result: ", predicted_name, class_probability)
