摘要

 近年來，計算機圖像技術的飛速發展使個人電腦上的美術創作進入一個新的階段，各種圖像處理軟件也越來越完善，普及程度不斷的提高。我們可以對圖像進行修飾、對圖形進行編輯、對圖像的色彩進行處理等。在實際生活和工作中，人們可以對數碼照相機拍攝下來的照片進行編輯和修飾，還可以在原圖像基礎上制作特效效果。如果和其它工具軟件配合使用，則可以進行高質量的廣告設計、美術創意和三維動畫制作。
 本文從圖象處理的基本原理開始闡述，探討了包括色彩調整、代數運算、幾何運算、濾鏡效果、藝術效果、扭曲效果和風格化七個模塊的處理。色彩平衡可以按照特定要求改變圖像中每個像素的亮度值；代數運算可以對兩幅圖象進行代數運算；幾何運算可以對圖象進行簡單的形狀處理；濾鏡效果是針對相臨像素間的關系來處理每個像素，達到一種特殊的效果。藝術效果是可以將圖象加工成精美的“藝術品” ；扭曲效果可以對圖像進行變形處理；風格化屬于破壞性濾鏡，通過置換像素生成繪畫或印象派的效果。

 Magic effect of image process with matlab
                
 
 
 Abstract
 
 In recent years, with the rapid development of computer image process that the creative arts on personal computers have come to a new stage, various image processing software has become more perfect and spread continuously. We can refine the image of graphics, editing the image and process the color of image. In real life and work, people can refine and edit the pictures of digital from camera, and make magic effect base on the origin image. If used with software and other tools, we can conduct high-quality advertising design, creative art and 3D animation.
 This paper expound begin with the basic image processing principles, and discussing seven modules of processing including color adjustment, algebra, geometry calculation, and filter effects, artistic effect and distortion effect . The brightness value of each image pixel can be changed by color balance processing in accordance with the specific requirements; algebra processing can perform a mathematical process with two image; geometric processing can change the shape of the images; Base on the relationship of adjacent pixels the filter effect can change each pixel to achieve a special effect. Images can be processed into beautiful "art" by Artistic effect; Images can be deformed by distortion effect processing; Style effects belongs to destructive filter effects, reaching painting or impressionism effect through replacing each pixel.
