In this paper, it is shown that nonlinear image enhancement can be used to improve the quality of a blurred image by using the concept of opportunity cost with image classification. However, one observes from computer simulation that the values of clipping and scaling parameters are quite different in image enhancement for various blurred images. Therefore, one aim of this paper is to develop an effective...
Image enhancement is a commonly used method for the improvement of the quality of blurred image. Among many image enhancement approaches, the nonlinear image enhancement method has a simple structure and can obtain a good processing effect. For various target images, it is difficult to decide the best combination of clipping and scaling parameters within the nonlinear image enhancement method. In...
It is well known that the B-spline filter can yield a very accurate algorithm for smoothing. In this paper, it is shown that a cubic B-spline filter can be used to improve the non-linear image enhancement method. In addition, a higher-frequency component is predicted to solve the blurred problem of an enlarged image. Furthermore, a novel non-linear image enhancement compensation algorithm is proposed...
