摘要
中文摘要 大自然中處處都充滿著色彩，而各種彩色影像紀錄、傳輸或重現的儀器在人類生活當中也扮演了舉足輕重的角色；縱使我們知道人眼感知到顏色本身就是一包含釵h因子的複雜行為，然而隨著科技日益進步，所有的人對於色彩描述及其重現的準確度只會有越來越嚴格的要求。為了能夠精確地捕捉和描述出各種物體（或影像）在不同的外在環境之下所呈現的色彩資訊，於是發展出多頻帶影像（Multi-spectral Imaging）的技術，這樣的技術不管是在色彩的擷取、重建、傳輸，甚至是在印刷色域上都提供了很大的進步空間。 這篇論文將對整個多頻帶影像（Multi-spectral Imaging）技術的動機、原理以及國內外相關的研究進度作一完整的介紹。除了實際模擬過去已經被提出的演算法，我們也針對多頻帶影像（Multi-spectral Imaging）相關的主題（例如物體辨識、多頻帶影像壓縮），提出一些想法；藉由驗證這些想法和分析既有的研究結果，最後我們歸結出這個新領域目前可能遇到的瓶頸和未來研究的方向。 整篇論文分成五個章節。第一章對於多頻帶影像（Multi-spectral Imaging）作一般性的介紹。第二章則是介紹顏色、人眼視覺成像、彩色影像儀器的原理概念。第三章內容為過去到現在在多頻帶影像（Multi-spectral Imaging）上的研究整理以及我們實際上的一些模擬結果。接著在第四章當中有我們所嘗試延伸多頻帶影像（Multi-spectral Imaging）相關主題所做的實驗成果。最後，第五章則將整篇文章作一總結與指出未來的研究方向。

Abstract There are plenty of colors in the world and the devices which record, transmit, or re-display color images, have taken important parts in human life. As the development of technology, people desire to gain more accurate colors for image recording and image reconstruction regardless of the exceptional complex behavior of human perception. Thus, there comes the technique of Multi-spectral Imaging, which aims to accurately acquire or describe color information of objects under arbitrary illuminants. It’s this technique that makes great progress in color acquisition, re-display, transmission, and even in printing industry possible. In this thesis, we have introduced the initial motivation and the principles of Multi-spectral Imaging technique and the researches that have been done by others until now. In addition to simulate the algorithms maintained in the past, we also proposed some ideas about the related research topics, such as object classification and image compression. By verifying these ideas and analyzing the research results on hand, we will draw a conclusion of the possible difficulties that was met now along with the possible future works in this new filed. This thesis consists of five chapters. A general introduction is made in chapter 1. Then the concept of color, the formation of human vision and the digital image devices are described in chapter 2. In chapter 3, the concept, applications and related works in Multi-spectral Imaging will be summarized and some of our simulated results will be given too. The experiments on multi-spectral imaging, its related topics and their simulation results are present in chapter 4. Finally, a concluding remark and future research directions will be given in chapter 5.
