Methods and apparatuses for image processing

摘要

Methods and apparatuses for image enhancement are provided, with which convolution operations can be carried out directly in a filter space, for example in a wavelet space, in particular directly on compressed data.

1. A method for image enhancement, including: recording an image,
applying a biorthogonal filter bank to the image, in order to generate an image in the filter space, applying a convolution operation to the image in the filter space in such a way that the result of the convolution operation is again present in the filter space, the convolution operation convoluting with a kernel that is based on a point spread function and the convolution operation includes a splitting of the kernel into several components, and outputting a result image on the basis of the result of the convolution operation.
