A Novel Transient Improvement with Overshoot Suppression

Abstract:

Article Preview

In conventional image enhancement methods, the noises and overshoot occur which degrade the image quality significantly accompanied with transient improvement. To obtain high quality image enhancement, a novel transient improvement with overshoot suppression and noise reduction is proposed. It employs a Laplacian of Gaussian operator and a Sobel operator to achieve transient improvement, and uses a nonlinear clamp filter in luminance and a median filter in chrominance for overshoot suppression. Experimental results indicate that it can achieve better transient improvement and sharpen the blurred edge effectively while suppressing or preventing overshoot.
