为了有效增强图像的细节信息，研究了基于无抽样Contourlet变换的图象增强方法。首先将待增强图像进行无抽样Contourlet变换，然后使用映射函数对无抽样Contourlet系数进行增强处理，最后进行无抽样Contourlet反变换得到增强后的图像。实验结果表明，该方法可以有效增强图像的微弱边缘信息。
為瞭有效增彊圖像的細節信息，研究瞭基于無抽樣Contourlet變換的圖象增彊方法。首先將待增彊圖像進行無抽樣Contourlet變換，然後使用映射函數對無抽樣Contourlet繫數進行增彊處理，最後進行無抽樣Contourlet反變換得到增彊後的圖像。實驗結果錶明，該方法可以有效增彊圖像的微弱邊緣信息。

In order to enhance image details, image enhancement method based nonsubsampled contourlet transform is researched in this paper. The image is first translated into nosubsamoled eontourlet domain, and then, the coefficients are mapped by mapping function. Finally, the enhance image is obtained by inverse nonsubsampled contourlet transform. Experimental results show that the method can enhance the feeble edges of an image.
