what bicubic interpolation

Three common bicubic interpolation algorithms of image processingA bicubic interpolation calculation involves 16 pixels, where (i ', J ') represents the pixels to be calculated in the source image containingThe pixel coordinate of the fractional

By chuckgao 2009 Recently, we have studied bilinear and bicubic algorithms for image scaling during video stream playback. Here is an algorithm that doubles the image in the latest project. For algorithm optimization, you can consider using the

In the process of image geometric transformation, the commonly used interpolation methods are nearest neighbor interpolation (near sampling method), bilinear interpolation and three convolution method. nearest neighbor interpolation: This is one of

Http://www.cnblogs.com/celerychen/archive/2010/11/25/3588222.htmlFirst, image amplification algorithmThere are many algorithms for image amplification, and the key is to use what interpolation method is used for unknown pixels. The following we will

In the field of film and television production, the problem of enlarging low-resolution images to high-resolution images is often involved, and sometimes the issue of adjusting non-square pixels to square pixels is also involved. This chapter
