WIDTH and HEIGHT parameters in OpenCV

Question

l'm a little bit confused on width and height parameter :

Is the height which is the first parameter or the second ?

HEIGHT,WIDTH= img.shape[0:2] or WIDTH,HEIGHt= img.shape[0:2]

and in resize function height=32 and width=100 or the inverse ?

image=cv2.resize(img, (32, 100), interpolation=cv2.INTER_NEAREST)

Answer 1

With .shape it's HEIGHT, WIDTH = img.shape[0:2]. The reason for this, is it's a numpy matrix, where the first value means number of rows, and the second is number of columns.

When you resize it's img = cv2.resize(img, (WIDTH, HEIGHT)).
