                         which has linear complexity on the number of pixels of the image. 
                         It allows us to reduce the execution time as we increase the 
                         number of Streaming Multiprocessors (SMs) on the GPU. We make use 
                         of a domain transformation and use a complex-valued recursive 
                         formulation of the Gaussian filter. The algorithm partitions the 
                         image in disjoint regions, where we compute in parallel the 
                         filtering operations, avoiding communication between regions. Our 
                         implementation leads to a real-time solution using a modern GPU. 
                         With the RTX 2080 Ti, we achieved an execution time of less than 
                         10 milliseconds for 2 filtering iterations on high-resolution RGB 
                         images of dimensions 2048x2048.",
