Yes, you can implement Gaussian blur in one pass, by sampling all n^2 pixels in the kernel (for kernel width n). It's usually faster to run it on the rows and columns in two passes, since then you have O (n) pixels to sample rather than O (n^2). This is not an approximation, since Gaussian blur is mathematically separable. hove electrician
