【正文】 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。 II 圖像增強(qiáng)技術(shù)通常有兩種方法：空間域法和頻率域法。 關(guān)鍵詞 ： 圖像增強(qiáng)；直方圖；圖像 平滑；鄰域平均；中值濾波 III Abstract The image in the transmission and conversion 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 outstanding, 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 outline 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 methods: spatial domain and frequency domain method. The spatial domain method is direct putation of pixel gray values in the spatial domain. This paper focuses on the spatial domain method, enhancement of digital image 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. Keywords ： Image Enhancement。 Median filtering IV 目 錄 摘 要 ..............................................................
