Blind reconstruction of sparse images with unknown point spread function

We consider the image reconstruction problem when the original image is assumed to be sparse and when partial knowledge of the point spread function (PSF) is available. In particular, we are interested in recovering the magnetization density given magnetic resonance force microscopy (MRFM) data, and we present an iterative alternating minimization algorithm (AM) to solve this problem. A smoothi...

Multiple-Image-Based Restoration for Motion Blur with Non-uniform Point Spread Function

A blind image restoration for non-linear motion blurs with non-uniform point spread functions based on multiple blurred versions of a same scene is proposed. The restoration is separately considered as identification and deconvolution problems. In the proposed identification process, an identification difficulty is introduced to rank an order of blur identification. A blurred image with the low...

Image Restoration with Mixed or Unknown Noises

This paper proposes a simple model for image restoration with mixed or unknown noises. It can handle image restoration without assuming any prior knowledge of the noise distribution. It is particularly useful for solving real life image restoration problems, since under various constraints, images are always degraded with mixed noise and it is impossible to determine what type of noise is invol...

Image Decomposition and Restoration for Blurred Images Using Filtering Techniques

In Image processing, image decomposition and restoration for blurred images are the significant challenges. Using bilateral filter, image is decomposed into two meaningful components. One is the cartoon component which is often called as geometrical part or sketchy approximation. Other is the texture component which is often called as oscillating part or small scale special pattern. Image resto...

Motion Blurred Image Restoration based on Super-resolution Method

Motion blur is a typical and common degradation in surveillance system. The problem of motion estimation based on super resolution reconstruction of multiple images is addressed in this paper. This paper presents a motion projection onto convex set (POCS) algorithm to restore an image from multiple blurred images. The inter and intra pixel shifts are used to compute a joined point spread functi...
