The Research Of Editing And Synthesis About Video Stream

Nowadays, computer and network is developing rapidly,video as a kind of medium to spread information has been applied widely,and all kinds of video equipment can be seen everywhere.Obviously,the field of video involves many technologies,such as the enhancement about video quality,size scale,format conversion,video decomposition and so on.At the same time,there’re more and more video packaging standards,video display devices.No doubt,these lead to the difficulty of video using.Henceforth,video technologies continue to make progress and studying video in depth is significant.Video editing and synthesis method are mainly researched in this paper.Fistly, the video format is introduced,especially,the AVI(Audio Video Interleaved) and the FLV(Flash Video).Secondly, Many algorithms used in video format conversion are analyzed in this paper,such as deinterlace,frame rate algorithm.Thirdly,using the Microsoft VFM (Video For Windows),the Video library function and OpenCV library decomposes video into the frame sequences. Video and image sequences can converse with each other,image sequence can be acquired by the video decompression.In the same way,through compression,the image sequence also can turn into video file.Then,do a simple image processing about the frames after decomposing by subtraction method.Finally, the research of image stitching has carried on in this paper,it made the simple introduction about image stitching technology and simulated the image synthesis.The image stitching technology has been widely used in today’s society,and it involves many aspects of life. With the rapid development of society and progress, people has a higher demand for information,such as continuity and universality about the video. Obviously, people would want to put more video image synthesize together, form a complete and continuous new picture. Panorama is a popular technology at present, the key technology of generating panorama is carried out on the adjacent images registration and stitching operation.Through the study and simulation,deep comprehending in video format conversion has formed.In addition,video decomposition and using subtraction method to dispose images are finished in the paper.The effect is obvious and it verifys the feasibility of processing method.After the research on image matching, a simple simulation is accomplished, the results are satisfactory.
