摘要 隨著計(jì)算機(jī)科學(xué)技術(shù)的不斷發(fā)展以及人們?cè)谌粘Ｉ钪袑?duì)圖像信息的不斷需求，數(shù)字圖像處理技術(shù)以其信息量大、處理和傳輸方便、應(yīng)用范圍廣等一系列優(yōu)點(diǎn)，成為人類獲取信息的重要來(lái)源和利用信息的重要手段，并在探測(cè)、遙感、生物醫(yī)學(xué)、工農(nóng)業(yè)生產(chǎn)、軍事、公安、辦公自動(dòng)化等領(lǐng)域得到了廣泛應(yīng)用。在實(shí)際應(yīng)用中，只要涉及到成像或者是圖像圖片都需要進(jìn)行圖像處理，因此研究圖像處理具有較深的實(shí)際意義。
MATLAB是一種優(yōu)秀的工具軟件，具有強(qiáng)大的運(yùn)算功能和圖形展示功能，是圖像處理變得更加的簡(jiǎn)單和直觀。本文介紹了MATLAB語(yǔ)言的特點(diǎn)和基本使用方法以及MATLAB圖像處理的手段，其包含圖像的編輯、圖像的變形、噪聲和濾波等。
本論文主要針對(duì)校園圖像應(yīng)用了圖像處理的相關(guān)技術(shù)，包括：圖像的運(yùn)算、圖像的變換、圖像的增強(qiáng)、圖像的分析、圖像的復(fù)原及圖像的形態(tài)學(xué)操作。進(jìn)行了均值濾波和中值濾波兩種濾波方法的仿真操作，通過(guò)對(duì)比發(fā)現(xiàn)中值濾波的效果更好；實(shí)現(xiàn)了sobel算子、log算子及canny算子的邊界分析方法，通過(guò)對(duì)比發(fā)現(xiàn)sobel算子檢測(cè)邊緣的效果更好；實(shí)現(xiàn)了維納濾波和盲目卷積兩種方法的圖像復(fù)原以及對(duì)圖像的形態(tài)學(xué)操作進(jìn)行了相關(guān)的仿真操作。

Campus based on MATLAB image processing and analysis
Abstract With the continuous development of computer science and technology as well as people in their daily lives constantly demand for image information, digital image processing technology for its large amount of information to facilitate the processing and transmission, a wide range of applications, such as a series of advantages, become human access to important information important means and use of information sources, and in the detection, remote sensing, bio-medical, industrial and agricultural production, military, public security, office automation and other fields has been widely used. In practical applications, insofar as the image forming or image need to be image processing, image processing and therefore have a deeper study of practical significance.
MATLAB is an excellent tool with powerful computing capabilities and graphical display capabilities, image processing becomes more simple and intuitive. This article describes the features and use of methods and means of basic image processing MATLAB MATLAB language, which includes an image editor, image distortion, noise, and filtering.
The thesis for the application of the related art image campus image processing, comprising: an image operation, image conversion, image enhancement, image analysis, image restoration, and image morphological operation. Simulated operation mean filter and median filter two filtering methods, found better results by comparing the median filter; achieve the sobel operator, log analysis and boundary operators son canny operator, by contrast found sobel operator edge detection results better; implements blind image restoration Wiener filtering and convolution of the two methods as well as the image of the relevant morphological operations simulation operations.

Keywords: digital image processing MATLAB software Image enhancement Image Analysis
