How i can take the average of 100 image using opencv?

Question

i have 100 image, each one is 598 * 598 pixels, and i want to remove the pictorial and noise by taking the average of pixels, but if i want to use Adding for \"pixel by pixel\"t

Answer 1

Suppose that the images will not need to undergo transformations (gamma, color space, or alignment). The numpy package lets you do this quickly and succinctly.

# List of images, all must be the same size and data type.
images=[img0, img1, ...]
avg_img = np.mean(images, axis=0)

This will auto-promote the elements to float. If you want the as BGR888, then:

avg_img = avg_img.astype(np.uint8)

Could also do uint16 for 16 bits per channel. If you are dealing with 8 bits per channel, you almost certainly won't need 100 images.
