WebGaussin Blur & Gamma Correction. Contrast stretching image contains noise, so blur the image with Gaussian kernel. As Gaussian distribution kernel can be linearly separable, we apply convolution with the same 1D-kernel along the x-axis and y-axis for performance (negligible for small kernels and low-res images).
