exrblur - perform a gaussian blur on an OpenEXR image
exrblur input.exr output.exr kernelsize
Performs a gaussian blur on the input image. This is useful for generating a whitepoint image for chromatic adaptation of locally adapting tone mapping algorithms. The kernel size for the blur is given as a fraction of the image width. So, a kernelsize of 0.25 will perform a blur with a kernel width 1/4 of the image width.
