Description: 老外编的的程序，可以成功运行，推荐下载学习-mosaic.m Code Description
The mosaic.m script operates as follows:
First, it converts the values of the images from unsigned int to double. This is done because most of the MATLAB operations use double as default type. Then, it asks for the points to be matched. Once it has this information it performs a transformation based on an estimate. The value of each pixel is then chosen using a bilinear interpolation. Finally, the mosaicked image is displayed.

Description: Bilinear filtering is a texture filtering method used to smooth textures when displayed larger or smaller than they actually are.
Most of the time, when drawing a textured shape on the screen, the texture is not displayed exactly as it is stored, without any distortion. Because of this, most pixels will end up needing to use a point on the texture that is between texels, assuming the texels are points (as opposed to, say, squares) in the middle (or on the upper left corner, or anywhere else it does not matter, as long as it is consistent) of their respective cells . Bilinear filtering uses these points to perform bilinear interpolation between the four texels nearest to the point that the pixel represents (in the middle or upper left of the pixel, usually).-Bilinear filtering is a texture filtering method used to smooth textures when displayed larger or smaller than they actually are.
