In chapter 2, a general digital watermarking frame is presented, including the generation, embedding and detection of watermark. in chapter 3, the concept of watermarking channel is presented, the modes of watermarking channel and image dct coefficients is proposed, the capacity of watermarking channel is evaluated by embedding watermarks to selected still image dct coefficients in direct spread spectrum. in chapter 4, a watermarking algorithms based wavelet multi - resolution is presented, by conjunction with human visual model, it keeps invisibility of watermark in host image and need not original image during detection
數字水印是一種新的數字媒體保護技術,它是將特定的信息(如版權信息、秘密消息等)嵌入到圖象、語音、視頻等各種數字媒體中,以達到版權保護等目的,同時,這種信息對宿主媒體的影響不足以引起人們的注意且有特定的恢復方法,此信息對非法接收者應該是不可見的,本文主要對數字水印的一般框架,靜止圖象dct系數的理論容量,圖象水印的嵌入和檢測,數字媒體防篡改以及數字水印的攻擊等問題進行了研究,提出了兩個新的水印算演算法。Then some key techniques in mpeg - 2 and mpeg - 4 recommendations are studied and compared in detail, including motion estimation, motion compensation, discrete cosine transform, inverse discrete cosine transform, variable length coding and layered description of picture and code stream
然後深入研究了mpeg - 2建議的視頻編碼標準,包括ts流、 ps流、時鐘恢復、視頻與音頻的同步、基於場的運動補償、 dct及變長編碼。In recent years, some new concepts of information security have been proposed, especially in the application of intellectual property right protection, copyright protection and tamper - proofing. information hiding and digital watermarking are new measures of digital media protection, which are processes of embedding hidden messages within digital media such as text, images, video and audio. the hidden messages could be copyright information, user distributor identification number, company logo, personal signature, control bits, or any information considered useful for a specific application
信息隱藏與數字水印技術就是一種新的數字媒體保護措施,它是將特定的信息(如版權信息、秘密消息等)嵌入到圖像、語音、視頻及文本文件等各種數字媒體中,以達到標識、注釋及版權保護等目的,同時,這種信息對宿主媒體的影響不足以引起人們的注意且具有特定的恢復方法,此信息對非法接收者應該是不可見、不可察覺的。At the beginning, this paper has some brief dissertation on the basic principle of the dsl and the multimedia data compression, the key technique of sdsl, the transport protocols, and the data transfer system structure based on the twisted - pair. then it gives an analysis of the point - to - point data link protocol ( ppp ) and the real - time transmission protocol in detail, which provide the side - to - side transmission service for audio frequency and video frequency data, and so on based on the these, we developed a multimedia sdsl modem system used to transfer data and phonetic
本文首先對dsl系統和多媒體數據壓縮技術的基本原理、 sdsl的關鍵技術、傳輸協議以及基於雙絞線的數據傳輸系統的結構進行了簡要的論述,並詳細分析了點到點的數據鏈路協議( ppp協議)以及實時傳輸協議,其為音頻、視頻等實時數據提供端到端的傳送服務。可以向接收端傳送恢復實時信號必需的定時和順序信息,並向收發雙方和網路運營者提供qos監測手段。分享友人
