The pixels that are closer to the one thatР Р†Р вЂљРІвЂћСћs to be estimated are given higher weights as compared to those that are further away. In addition to going 2Р вЂњРІР‚вЂќ2 neighborhood of known pixel values, Bicubic goes one step beyond bilinear by considering the closest 4Р вЂњРІР‚вЂќ4 neighborhood of known pixels - for a complete of 16 pixels. There are various interpolation algorithms one of them is Bicubic Interpolation. Interpolation algorithms are predominantly used for resizing and distorting a high-resolution image to an occasional resolution image. The accuracy of those algorithms is increased significantly by increasing the number of neighboring pixels considered while evaluation of the new pixel value. Betting on their complexity, these use anywhere from 0 to 256 (or more) adjacent pixels when interpolating. Interpolation AlgorithmsР вЂќР’Вifferent interpolation algorithms include the nearest neighbor, bilinear, bicubic, and others.

The greater the quantity of already known values, the higher would be the accuracy of the estimated pixel value. For example: if you wanted to understand the pixel intensity of a picture at a selected location within the grid (say coordinate (x, y), but only (x-1,y-1) and (x+1,y+1) are known, youР Р†Р вЂљРІвЂћСћll estimate the value at (x, y) using linear interpolation. Interpolation works by using known data to estimate values at unknown points. Note: While applying interpolation algorithms, some information is certain to be lost as these are approximation algorithms. The results of resizing greatly vary looking on the kind of interpolation algorithm used. Applications of image resizing can occur under a wider form of scenarios: transliteration of the image, correcting for lens distortion, changing perspective, and rotating a picture. Image resizing is a crucial concept that wishes to augment or reduce the number of pixels in a picture.
