Combines adjacent pixels to produce a lower-resolution and less noisy output image. Usually, binning is implemented by an image sensor before A/D conversion. Some camera models don’t however support this feature, and it may also be useful to simulate the effect in software.
This tool produces an output image that halves both horizontal and vertical resolution by calculating the average of a 2x2 neighborhood.
image: Any image.
image: A downscaled image. The type of the output image is the same as that of the input.
