چکیده

In this paper we examine the use of compound Gauss Markov random fields (CGMRF) to restore severely blurred high range images. For this deblurring problem, the convergence of the Simulated Annealing (SA) and Iterative Conditional Mode (ICM) algorithms has not been established. We propose two new iterative restoration algorithms which extend the classical SA and ICM approaches. Their convergence is established and they are tested on real and synthetic images.

Removing Quantization Artifacts in Color Images Using Bounded Interval Regularization

Coarsely quantized images will exhibit false contours in smooth low gradient regions. Images intended for standard displays such as CRT monitors can show contours when moved to high dynamic range devices such as HDR displays and film. While various methods exist for noise removal and image restoration, they are not able to remove these contouring artifacts completely and can impose substantial ...

Blind restoration of blurred and noisy images

This paper presents a technique for deblurring noisy images. It includes two processing blocks, one for denoising and another for blind image restoration. The denoising step is based on the theories of singular value decomposition and compression-based filtering. The deblurring step is based on a double-regularization technique. Experimental results show that the combination of these techniques...
