What is interpolation in imaging?
Image interpolation occurs when you resize or distort your image from one pixel grid to another. Image resizing is necessary when you need to increase or decrease the total number of pixels, whereas remapping can occur when you are correcting for lens distortion or rotating an image.
How do you interpolate a picture?
Image interpolation is generally achieved through one of three methods: nearest neighbor, bilinear interpolation, or bicubic interpolation. Since each method has its own merits and challenges, the choice of appropriate method is based on state of affairs.
Which interpolation method is best?
Radial Basis Function interpolation is a diverse group of data interpolation methods. In terms of the ability to fit your data and produce a smooth surface, the Multiquadric method is considered by many to be the best.
