gaussian_smooth(): filter images with Gaussian blur.

-----

Gaussian blur is a filter used to smooth or blur a digital picture. It replaces pixels with a weighted average of surrounding pixels. The weights come from the Gaussian probability distribution, so the nearest pixels are more influential.

高斯模糊是用於平滑或模糊數位照片的濾波器。它將像素替換為周圍像素的加權平均值。權重來自高斯機率分佈，所以越近的像素影響力越大。
