The purpose of this theme is to classify sar images into four regions : man - made targets ( vehicles and buildings ), natural targets ( trees and shrubbery ), background ( field and grass ) and shadow ( the target shadow and mirror scatter ). on the one hand, the processed results can be directly used as image product, which offer necessary parameters for expert ' s interpretation to build up an independent auxiliary interpreting system. on the other hand, the results can be introduced into sar image interpreting system as the replacing target detection and discrimination models with layer rois ( region of interest ) in order to provide potential target chips
具體內容為：根據sar圖像基本特性，提取可靠特徵，將圖像區分為人造目標（機動車輛、建築物等） 、自然目標（樹木、灌木、樹林等） 、背景（草地、平地、植被等）和陰影（目標陰影、鏡面散射體等）四種類別，為不同的應用提供對應的感興趣區域（ roi ） 。 -
After analyzing the two roi coding methods of jpeg2000 standard, their shortcoming is pointed out, and then a novel roi image coding method with utilizing information hiding technique is proposed. in this scheme, some coded information of the background is embedded into the redundant bits of the roi coefficients. the relative quality of rois and background can be adjusted by changing the quantity of embedded information
感興趣區編碼是jpeg2000標準所提供的一項重要特性，本文對標準中規定的兩種感興趣區編碼方法進行了分析，指出其不足之處，而後創造性地提出利用信息隱藏技術來對其進行補充，將部分背景區的編碼信息隱藏在感興趣區系數的冗餘位，通過控制嵌入量可以調節感興趣區和背景區的相對質量。 -
Signal interaction between no and reactive oxygen intermediates ( rois ) in the plant have already been reported and recently nitric oxide was reported to be a novel component of abscisic acid signaling in stomatal guard cells
最近的研究表明no是植物在病原菌侵害后激活防禦反應的信號之一。在植物中， no和活性氧（ rois ）的相互作用已有報道。 -
Delledonne and colleagues demonstrated that, in soybean cell suspension, the efficient induction of hypersensitive cell death requires a balance between rois and no production
Delledonne等揭示在蠶豆懸浮細胞中誘導細胞超敏感死亡需要no和rois的產生有一個平衡。 -
Region - of - interest ( roi ) image coding is a new feature in the newly published jpeg2000 still image compression standard, which allows rois to be coded with better quality than the rest of an image, i. e., background
感興趣區域（ roi ）圖像編碼處理，是聯合圖像專家組（ jpeg ）新推出的jpeg2000靜態圖像壓縮標準中提供的一種新特性。 -
The paper analysis the image compression standard of jpeg2000 for the generality, describe the roi coding of jpeg2000, in the same time, the author briefly introduce wavelet theory which is the basis of the discrete wavelet algorithm adopted by jpeg2000, analysis the algorithm of roi based on discrete wavelet transform. finally the author carry on the detailed analysis to ebcot algorithm and to the multiple rois method, analysis every block of encoding, proposes one coding algorithm of roi based on ebcot and proposes one method can realize image multiple roi and multiple quality compression
本文從一般性出發分析了jpeg2000標準，對jpeg2000的roi編碼進行了描述，同時對jpeg2000採用的離散小波變換演算法的理論基礎進行了介紹，分析了基於小波變換的圖像感興趣區域編碼方法。最後特別對jpeg2000標準的ebcot演算法和多興趣區域編碼方法進行了詳細的研究，對編碼的各個環節進行了分析，提出了基於ebcot的感興趣區域編碼演算法及實現多興趣區域多質量的壓縮的編碼方法。
