最邻近插值(Nearest neighbor interpolation) 这里只用基本的灰度图来介绍。 D D D是目标图像的灰度,S是原本图像的灰度 D ( x , y ) = S ( [ x + 0.5 ] , [ y + 0.5 ] ) D(x,y)... 查看原文 图像增强(emphasize illuminate, scale_image_max)和极坐标转换(polar_trans_image) ;bilinear"双线...

To perform a pure sinc interpolation, every voxel in the image should be used to sample a single point. This is not feasible due to speed considerations, so an approximation using a limited number of nearest neighbours is used. Because the sinc function extends to infinity, it is often ...
