Algorithm encapsulation of bilinear and bicubic

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

The commonly used interpolation algorithm in image geometric transformation (scaling, rotation)

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
