Utilizes a 2x2 environment of pixels on an average. This filter blends new interpolated pixels with the original image pixels to generate a larger image with more detail.

Utilizes a 4x4 environment of pixels on average. This filter maintains the innermost pixels and discards all the extra details from a given image.

Enhances the ability to identify linear features and object edges of a given image. This filter uses the sinc resampling function to reconstruct the pixelation of an image and improve its quality.
