Asirvadam Lila Iznita Image enhancement Thresholding Contourlet transform Wavelet transform Transformation function Image processing Image denoised Organized by School of Mechatronic Engineering (UniMAP) & co-organized by The Institution of Engineering Malaysia (IEM), 11th - 13th October 2009 at Batu Feringhi, Penang, Malaysia. A degraded image mainly has dark shadows, over bright regions and blurred details. These images are usually affected by noise. This paper proposes a method which tries to avoid this problems. Image denoised image is further treated by a uniquely designed new transfer function. it is used to treat the contourlet transform coefficients. The contourlet transform is a directional extension of wavelet transform thus its application has a profound effect in image enhancement application. The results found are encouraging. All important features of the image are kept with out introducing artifacts and color distortion. The results look more natural. 2009-11-13T01:59:13Z 2009-11-13T01:59:13Z 2009-10-11 Working Paper p.2A9 1 - 2A9 5 http://hdl.handle.net/123456789/7271 en Proceedings of the International Conference on Man-Machine Systems (ICoMMS 2009) Universiti Malaysia Perlis |
