The main purpose is to handle the graduation certificate and related files, and put them on record.

Image information collection skills

The amount of image data obtained from the digitization of image information is huge, and the information must be compressed by coding technology. In a sense, coding and compression technology is the key to realize image transmission and storage. Many mature coding algorithms have been applied to image compression. Commonly used are image prediction coding, transform coding, fractal coding, wavelet transform image compression coding and so on.
