Abstract
The use of local feature descriptors of an image to generate compressed image data and reconstruct the image using image patches that are external to the image based on the compressed image data may increase image compression efficiency. A down-sampled version of the image is initially compressed to produce an encoded visual descriptor. The local feature descriptors of the image and the encoded visual descriptor are then obtained. A set of differential feature descriptors are subsequently determined based on the differences between the local feature descriptors of the input image and the encoded visual descriptor. At least some of the differential feature descriptors are compressed to produce encoded feature descriptors, which are then combined with the encoded visual feature descriptor produce image data. The image data may be used to select image patches from an image database to reconstruct the image.
