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

Firstly- convert images to floats. You have N=100 images. Imagine that a single image is an array of average pixel values of 1 image. You need to calculate an array of average pixel values of N images.

Let A- array of average pixel values of X images, B - array of average pixel values of Y images. Then C = (A * X + B * Y) / (X + Y) - array of average pixel values of X + Y images. To get better accuracy in floating point operations X and Y should be approximately equal

You may merge all you images like subarrays in merge sort. In you case merge operation is C = (A * X + B * Y) / (X + Y) where A and B are arrays of average pixel values of X and Y images
