The paper describes the background ,significance and development status of the color image enhancement technology .At the same time, the paper describes several mon grayscale image enhancement technology, and emphasizes the contact of the color image enhancement technology and grayscale image enhancement technology. Then the paper focus on description of the histogram equalization principle and say some about space model transformation. Finally the paper adopts the RGB enhancement algorithm , the HSV enhancement algorithm and the tensile of proportion of histogram to achieve the goal of simulation , and describes the steps to achieve the goal. After the color image enhancement simulation, I conclude by analyzing the results. KEY WORD: Grayscale image enhancement。 Color image enhancement。 Histogram equalization。 Model transformation. 目錄 第一章 緒論 .................................................................................................................... 1 彩色圖像增強技術(shù)研究背景及意義 ..................................................................... 1 彩色圖像增強技術(shù)的發(fā)展動態(tài) ............................................................................ 2 顏色理論 ................................................................................................. 2 彩色圖像增強發(fā)展動態(tài) ............................................................................ 3 本論文的主要內(nèi)容和結(jié)構(gòu)安排 ............................................................................ 3 第二章 圖像增強技術(shù)介紹 ............................................................................................... 5 灰度圖像增強技術(shù) .............................................................................................. 5 .................................................................................................. 5 分段線性變換 .......................................................................................... 5 非線性變換 ........................................................................................................ 6 .................................................................................................. 6 .................................................................................................. 7 ........................................................................................... 7 Gamma 變換 .............................................................................................. 8 直方圖均衡 ........................................................................................................ 8 彩色圖像增強技術(shù) .............................................................................................. 9 顏色空間 ................................................................................................. 9 幾種常用的彩色圖像增強技術(shù) ................................................................ 12 第三章 設(shè)計方案 ........................................................................................................... 15 RGB模型增強算法 ............................................................................................ 15 HSV模型增強算法 ............................................................................................ 15 ................................................................................................ 15 第四章 結(jié)果分析 ........................................................................................................... 17 RGB模型增強后，對選取的增強前后的彩色圖像和直方圖分別進行對比分析 ..... 17 HSV模型增強后，對選取的增強的前后圖像和直方圖分別進行對比分析 ............ 18 , 對拉伸前后的彩色圖像和直方圖分別進行對比分析 ............ 19 第五章 總結(jié) .................................................................................................................. 22 參考文獻 ........................................................................................................................ 23 致 謝 ......................................................................................................................... 25 附錄 ............................................................................
