As the military and industry is developing dramatically, to enhance the low - contrast digital image has become one of the important areas in image processing. there are two traditional methods to enhance the low - contrast digital image : the methods based on frequency and the method based on time. the histogram enhancement, the most popular way to enhance, is representing the latter one ; while the methods based on frequency often uses wavelet transform, ft ( flourier transform ), dct ( discrete cosine transform ) to enhance
隨著軍事和工業上的發展需要，低對比度數字圖像的增強越來越成為數字圖像處理中的一個重要領域，傳統的增強方法分為頻域法和空域法兩大類，其中空域法的代表為直方圖增強法，這也是最為流行的增強方法，頻域法中用的較多的是基於小波變換，傅立葉變換和離散餘弦變換的增強方法，本文介紹的是基於小波神經網路的頻域增強法。
