Its probably not possible, but I would really love a fast gaussian blur as a pix_ object. convolved blur does not have the image quality that would be really nice. Is there something that is similar in quality as gaussian blur but less intensive?
There's a law of probability that says that as you repeat a convolution product of Measures it will tend towards a gaussian (normal law) Measure with some centre and some std-deviation. In particular, repeating a uniform 1x3 blur will give something with zero centre (because of symmetry of the 1x3 kernel) and a std-deviation almost proportional to square-root of the number of compositions of the convolution. I think that this is the key to a fast simili-gaussian blur.
Does that sound right?
