2、 要圖像在傳送和轉(zhuǎn)換時(shí)會(huì)造成圖像的某些降質(zhì)，所以有必要對(duì)降質(zhì)的圖像進(jìn)行改善處理。其中的一種方法是不考慮圖像質(zhì)量降低的原因，只將圖像中感興趣的特征有選擇的突出，從而衰減次要信息。這種方法能夠提高圖像的可讀性，改善后的圖像不一定逼近原始圖像，但能夠突出目標(biāo)的輪廓、衰減各種噪聲、將黑白圖像轉(zhuǎn)換成色彩圖形等。這類方法通常稱為圖像增強(qiáng)技術(shù)。AbstractThe image in the transmission and conversion

3、cases will cause some blurred image, so，it is necessary for the image to have an improved treatment. One way is to not consider the reasons for degradation of image quality, the characteristics of the image selected outs

4、tanding, thereby attenuating less important information. This method can improve the readability of the image, the image after improvement is not necessarily approximate to the original image, such as highlighting the ou

5、tline of the target, the attenuation of noise, the black and white images into color graphics. This kind of method is usually called the image enhancement technology.Image enhancement technology usually has two kinds of

6、 methods: spatial domain and frequency domain method. The spatial domain method is direct computation of pixel gray values in the spatial domain. This paper focuses on the spatial domain method, enhancement of digital im

7、age processing are studied, emphatically introduces the histogram equalization and histogram of image smoothing, neighborhood averaging and median filtering. And VC++ is used to realize the method for image processing.Ke
