Quasimondo : Incubator : Processing : Stack Blur
Stack Blur: Fast But Goodlooking This is a compromise between Gaussian Blur and Box blur It creates much better looking blurs than Box Blur, but is 7x faster than my Gaussian Blur implementation. I called it Stack Blur because this describes best how this filter works internally: it creates a kind of moving stack (or maybe a "Tower of Hanoi" kind of structure) of colors whilst scanning through the
Quasimondo : Incubator : Processing : Superfast Blur
A Superfast Blur Algorithm It may not look as beautiful as a Gaussian blur, but I think that a box blur can't get any faster than this. The specialty about this algorithm is that its speed is almost independent of the used radius. This works, because the convolution kernel is not recalculated on each pixel: scanning through the image the algorithm just adds one new pixel to the kernel and at the s
