It says that depth ( ) function returns the depth of an individual channel and channels ( ) returns the number of channels in image. Thus, in your case, image seems to have depth of 16bits with number of channels equal to 4.

WebFor example, let's say we have a 100 x 100 Mat object of type CV_8UC3. Each pixel value will take 8 bits and there will be three such values for each pixel (three channels). That takes it to 24 bits per pixel. There are 100 x 100 = 10,000 pixels in total, which means a total space of (24 x 10,000) bits = 30 kilobytes.
