Those images appear to already be grayscale to me. However, on the chance they are not, you could use rgb2gray() on the image.

Put all the images into a 3D array with the third dimension being the image number. Then take mean(The3DArray, 3) to take the mean between the images. Note that the result will be floating point not uint8 so you might want to uint8() the result if you plan to display it.

No.. you are not getting me. Actually let's say i have 10 images in a folder, now i have to convert these images to a single image by averaging the images so that it have features of all 10 images. this is what we call gait energy image. And yeah..Thank you for replying sir
