In Python Numpy you can get array length/size usingnumpy.ndarray.sizeandnumpy.ndarray.shapeproperties. Thesizeproperty gets the total number of elements in a NumPy array. Theshapeproperty returns a tuple in (x, y). Advertisements You can get the length of the multi-dimensional array with the...

When working with OpenCV Python, images are stored in numpy ndarray. To get the image shape or size, use ndarray.shape to get the dimensions of the image. Then, you can use index on the dimensions variable to get width, height and number of channels for each pixel. In the following cod...
