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...
متن کاملMotion-Blurred Particle Image Restoration for On-Line Wear Monitoring
On-line images of wear debris contain important information for real-time condition monitoring, and a dynamic imaging technique can eliminate particle overlaps commonly found in static images, for instance, acquired using ferrography. However, dynamic wear debris images captured in a running machine are unavoidably blurred because the particles in lubricant are in motion. Hence, it is difficult...
متن کاملRestoration of Motion Blurred Image Using Spatial Domain
In image restoration, it is nearly always assumed that the point-spread function of the degrading system, as well as the variance of the observation noise and a model of the original image, is known a priori. Since these parameters are unknown for practical images of interest, they have to be estimated from the noisy blurred images themselves. This thesis presents a maximum likelihood approach ...
متن کاملRestoration of Motion-Blurred Image Based on Border Deformation Detection: A Traffic Sign Restoration Model
Due to the rapid development of motor vehicle Driver Assistance Systems (DAS), the safety problems associated with automatic driving have become a hot issue in Intelligent Transportation. The traffic sign is one of the most important tools used to reinforce traffic rules. However, traffic sign image degradation based on computer vision is unavoidable during the vehicle movement process. In orde...
متن کاملImage Restoration with Two-Dimensional Adaptive Filter Algorithms
Two-dimensional (TD) adaptive filtering is a technique that can be applied to many image, and signal processing applications. This paper extends the one-dimensional adaptive filter algorithms to TD structures and the novel TD adaptive filters are established. Based on this extension, the TD variable step-size normalized least mean squares (TD-VSS-NLMS), the TD-VSS affine projection algorithms (...
