Title: | Building compression scheme using cross point region theory | Authors: | Pham Hoang Thao | Keywords: | Cross-point region;Broadcast production;C.B. Jones algorithm;Raw video;MPEG structure;Compression | Issue Date: | 2015 | Publisher: | Vietnamese-German University | Abstract: | Raw video which is captured from camera, video card, recorder units is important in broadcast production. The data is not pre-processed and editor can modify easily the brightness, contrast, color temperature... However the size of RAW video is often big. Hence, it requires a lossless compression method. The aim of the thesis is to build a lossless compression scheme for video based on the structure of Motion Expert Picture Groups MPEG to use its advantages for encode and decode RAW video. The lossless compression method includes analyzing frames of sequence into intra frames and prediction frames, cross-point region coding and arithmetic C.B. Jones algorithm. This method gives the result compares to lossless compression WinZip, WinRar in many cases. The thesis shows many ways of Motion Vector Estimation and chooses the best suitable for broadcasting. |
