  Loading images progressively using Gaussian blur

The popular online publishing platform Medium has adopted an impressive image loading mechanism -- pure color - blur image loading - real image loading. Since images on Medium usually have high definition, it takes much time to load an image and hence brings a bad user experience if rendering the image after it's completely downloaded. The solution Medium comes out is to preload an small image when the real image is being loaded.  On Medium, the HTML code will have below pattern ...

  Gaussian Blur Algorithm

Usually, image processing software will provide blur filter to make images blur. There are many algorithms to implement blur, one of them is called Gaussian Blur algorithm. It utilizes Gaussian distribution to process images. This article is to introduce Gaussian Blur algorithm, you will find this a simple algorithm. In fact, it is a kind of data smoothing which can be used in many situations. 1. Gaussian Blur theory The so called blur can be understood as taking a pixel as the average value of...
