Abstract
A computer implemented method for applying a numerical approximation of a convolution of image I as represented by hierarchical signals aof level l with filter f, said method including the steps of: generating a forward transformation by applying a convolution between aand kernel hfor each level of hierarchy l and by down-sampling the result of convolved aand h; generating a backward transformation by applying, for each level of hierarchy l, a convolution between kernel hand an up-sampled forward transformation and combining the result with a convolution of awith kernel g; and combining the forward transformation with the backward transformation, to yield âbeing an approximation of a convolution between a and f, wherein kernels h, h, and g are optimized kernels of filter f.
