為了達到實時性要求，在滿足人眼視覺的光信息量基礎上，對帶寬壓縮的理論問題進行了研究，提出了基於離散頻譜的帶寬壓縮演算法，並給出了結果。In the telerobot, there are video system and sensors used to measure the hardness of the grabbed object and the resistance. moreover, the image of on spot is transmitted to the screen in front of the operator by wireless communication system. in the meantime, the hardness of the grabbed object and the resistance in working can be judged by the feedback force of the master manipulator
為提高遙操作的視覺臨場感，提出虛擬現實輔助遙操作的控制策略，不僅為操作者提供友好的人機交互界面，彌補單一視頻反饋無線通訊伴隨的圖像抖動及模糊不清，而且在一定程度上緩和了遙操作系統中普遍存在的大時延問題所帶來的不利影響。The subimage of the lowest frequency ( ll4 ) is carried out lossless compressed coding ; 2 the subimages on diagonal direction of the highest frequency ( hhl ) is abandoned and is not carried out coding, because it is of great probability for zero, and it little affects visual
其主要包括對最低頻子帶單獨進行無損壓縮編碼，對最高頻對角線方向子帶捨去不編碼。對其餘各子帶根據視覺特點的不同，分別分配不同的比特數並按其進行零樹量化，最後再遊程編碼。Algorithms of video segmentation that are good adaptive character and real time are crucial to the final mpeg 4 coding products there exist the contributions in this dissertation as follows obtaining the edge of video objects is crucial to the video segmentation, author researches the features of human being visual, especially giving a description of mach band that is usually used in the image processing, and builds a model of mathematics, researching the mach band of color image
（ 1 ）視頻分割的關鍵是獲得視頻對象的邊界，邊緣檢測很重要，本論文以人類的視覺系統的特性為出發點，對圖像處理中經常應用的馬赫帶現象進行了詳盡的分析並進行了數學建模，研究分析了彩色圖像的馬赫帶現象。在對馬赫帶圖像分析的基礎上，得出了人類視覺系統對圖像邊緣能識別的最小灰度差和彩色差曲線。Based on the analysis of image wavelet transformation and the space / frequency distributing characteristics of different subbands " coefficients, this dissertation fully exploits the following theories and methods : scalar quantization, vector quantization, trellis coded quantization, trellis coded vector quantization, vector classification, codebook expansion and weighted mean square error rule basing mankind visual characteristics, etc. from different angles of information amalgamation, it develops several innovative algorithms of image compression and coding, gives their realization schemes, and makes plentiful simulation tests
本文在分析了圖像小波變換的原理和子帶系數空間及頻率分佈特點的基礎上，充分利用標量量化、矢量量化、網格編碼量化、網格編碼矢量量化、矢量分類、碼書擴展和基於人眼視覺特性的加權均方誤差準則等思想和方法，從信息融合的不同角度展開了對小波圖像的壓縮編碼研究，同時也討論了這些方法在靜止圖像量化中的具體應用。In order to improve measurement accuracy, methods of high resolution, high frame rate and much vision pot are used in image capturing. it brings issue of high image transmitting bandwidth and big storage space. the hardware & software architecture of image capturing system encounter strict challenge against image data transmission and processing in real time
在動態視覺測量中，為了提高測量精度，通常採用高解析度、高幀頻的相機在多視點進行採集，這樣就帶來了圖像數據傳輸的帶寬高，圖像數據存儲容量大的問題，這對圖像採集系統的硬體和軟體結構設計，特別是在實時性傳輸和提高圖像處理速度方面都提出了較高的要求。To roll - out as many multiplexes that could be squeezed at the initial stage of dtt transmission, as proposed in the consultation paper, would not only be impractical and have little market sense, but would also cause disturbance or disruption of reception of existing free terrestrial tv which would be of great disservice to the people of hong kong
政府建議于數碼地面電視傳輸初期便盡量推出多條數碼頻道平臺，這不僅是不切實際和缺乏市場觸覺的做法，而且亦對現有免費地面電視的接收造成干擾，為香港市民帶來不便。Video programs with strong visual impact can change the existing situation where there is limited content provided and give free play to bandwidth
