- Nearest neighbor interpolation: to sum up, it is to add and to guess. First it adds a heap of "blank" pixels to an image, and tries to guess what each blank pixel should be filled with based on its 4 adjacent pixels.
- Bicubic interpolation: it is to add pixels to an image and take on a color based on the 16 nearby pixels. The main purpose is to smooth the color and make the added pixels look as soft as possible.
- Bilinear interpolation: differently, it only checks the two neighboring blocks. The main purpose is to make the image look sharp.
