Description: Abstract: Effective data processing is required with the fast development of multimedia technology. Compressed-domain images/video processing techniques have captured the attention of many researchers in recent years, and research on face detection and tracking in compressed-domain video becomes a new trend. Based on the analysis of the background and research status, some important future directions are presented.

Description: 隐藏语音信号
信息隐藏于1994年的国际图像处理会议上(ICIP)正式提出,它通过信号处理的方法将隐藏信息嵌入到宿主(声音、图像、视频和文档等)中，具有不可感知性-只有通过专用的检测器才能获取该隐藏信息。同时隐藏信息并不会影响宿主的内容，具有很强的主观听觉或视觉上的欺骗性。-Hide voice signal information hiding in 1994, the International Conference on Image Processing (ICIP) formally proposed, through signal processing methods will be hidden information embedded into the host (sound, images, video and documents, etc.), can not be perceived sexual- only through a dedicated detector to obtain the hidden information. At the same time, hide information and will not affect the contents of the host, and highly subjective hearing or visually deceptive. Platform: |

Description: 解Demosaici，使用连续逼近的方法！-Motion-compensated (MC) video coding has been dominating in the past decades. From MPEG-1/2 to MPEG-4, H.263 and the latest H.264, we have witnessed that the accumulative improvement of MC video coding. However, what lacks in the standardization-propelled research is to maintain a healthy skeptism toward the role of MC in video coding. In this project, we attempt to challenge the current video coding paradigm by proposing a sound alternative that does not involve any explicit motion estimation or compensation. Instead, motivated by the duality between edge profile of 2D images and motion trajectory of 3D video Platform: |
