This normally means that the first of the 3 pixels is selected as the output pixel value and the rest two pixels are discarded. However, I want to perform downsampling by a factor of 3 such that the average of the three pixels is taken and selected as the output value.

By comparison, downsampling process should be a bit more familiar to readers who have done some computer graphics or image processing and know of aliasing in this context.
