A Novel Transient Improvement with Overshoot Suppression
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.
