I. Introduction
In remote display protocols, screen compression technologies are made used to reduce the often limited network bandwidth as well as quality of display to satisfy demands of user. The server may compress a screen image with some coding before sending the image across the network, and the client then performs the corresponding decompression operation after receiving the image. Based on the observation that not all image elements on the display have the same type, it makes no sense to use the same coding for everything-that would use excessive network bandwidth and give lesser user experience. So, it is wise to apply a screen image classification to determine preferred type of compressor for the image content. In particular, the server classifies the screen compound image, which are often mixed with textual, graphical or pictorial contents, and based on that classification determines a coding with which to encode each image content, and a fidelity to use on the encoding. The server performs that encoding with the coding and the fidelity, and then sends this encoded image to the client. So, we realize that screen image classification is a key challenge in compression decision, not only choosing suitable codings for screen image contents, but also the quality setting to use for a particular coding. PCoIP [1], which is invented by Teradici Corp, is a multi-codec protocol that continuously analyzes and decomposes the image elements-graphic, text, icons, video, etc.-and compresses them with the right coding for each pixel. This enables efficient transmission and decoding and saves bandwidth while delivering best user-experience.
