摘要
近年來(lái)，計(jì)算機(jī)圖像技術(shù)的飛速發(fā)展使個(gè)人電腦上的美術(shù)創(chuàng)作進(jìn)入一個(gè)新的階段，各種圖像處理軟件也越來(lái)越完善，普及程度不斷的提高。我們可以對(duì)圖像進(jìn)行修飾、對(duì)圖形進(jìn)行編輯、對(duì)圖像的色彩進(jìn)行處理等。在實(shí)際生活和工作中，人們可以對(duì)數(shù)碼照相機(jī)拍攝下來(lái)的照片進(jìn)行編輯和修飾，還可以在原圖像基礎(chǔ)上制作特效效果。如果和其它工具軟件配合使用，則可以進(jìn)行高質(zhì)量的廣告設(shè)計(jì)、美術(shù)創(chuàng)意和三維動(dòng)畫制作。
本文從圖象處理的基本原理開(kāi)始闡述，探討了包括色彩調(diào)整、代數(shù)運(yùn)算、幾何運(yùn)算、濾鏡效果、藝術(shù)效果、扭曲效果和風(fēng)格化七個(gè)模塊的處理。色彩平衡可以按照特定要求改變圖像中每個(gè)像素的亮度值；代數(shù)運(yùn)算可以對(duì)兩幅圖象進(jìn)行代數(shù)運(yùn)算；幾何運(yùn)算可以對(duì)圖象進(jìn)行簡(jiǎn)單的形狀處理；濾鏡效果是針對(duì)相臨像素間的關(guān)系來(lái)處理每個(gè)像素，達(dá)到一種特殊的效果。藝術(shù)效果是可以將圖象加工成精美的“藝術(shù)品” ；扭曲效果可以對(duì)圖像進(jìn)行變形處理；風(fēng)格化屬于破壞性濾鏡，通過(guò)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.
