Abstract
A method includes obtaining an image having M sections and each section having N pixels. The method further includes deriving N sub-images from the image, wherein each sub-image has M sections and each section has N pixels. The i-th pixel of the j-th section of the i-th sub-image has a pixel value equal to a pixel value of the i-th pixel of the j-th section of the image and other pixels of the j-th section of the i-th sub-image are set to 0, where i traverses from 1 to N, and j traverses from 1 to M. The method further includes providing N projection patterns and calculating a projection for each sub-image by performing convolution of the respective sub-image with a corresponding one of the projection patterns, thereby obtaining N projected sub-images. The method further includes summing up the N projected sub-images, thereby obtaining a projection of the image.
