Multichannel Regularized Iterative Restoration ofMotion Compensated Image

چکیده
Restoration of image sequences is an important problem that can be encountered in many image processing applications, such as, visual communications, robot guidance and target tracking. The independent restoration of each frame in an image sequence is a suboptimal approach because the between-frame correlations are not explicitly taken into consideration. In this paper we address this problem by proposing a multichannel restoration approach. The multiple time-frames (channels) of the image sequence are restored simultaneously by using a multichannel regularized least-squares formulation of the problem. The regularization operator captures both within and between-frame (channel) properties of the image sequence with the explicit use of the displacement vector eld. We propose a number of diierent approaches to obtain the multichannel regulariza-tion operator, as well as, an algorithm to iteratively compute the restored images. We present experiments that demonstrate the value of the proposed multichannel approach.

متن کاملMultichannel Regularized Iterative Restoration of Image Sequences
The recent advances in visual communications make restoration of image sequences an increasingly important problem. In addition, this problem finds applications in other fields such as robot guidance and target tracking. Restoring the individual frames of an image sequence independently is a suboptirnal approach because the between frame relations of the image sequence are not explicitly incorp...
متن کاملIterative regularized mixed norm multichannel image restoration
We present a regularized mixed norm multichannel image restoration algorithm. The problem of multichannel restoration using both withinand between-channel deterministic information is considered. For each channel a functional that combines the least mean squares (LMS), the least mean fourth (LMF), and a smoothing functional is proposed. We introduce a mixed norm parameter that controls the rela...

In this paper, we develop a deterministic regularized mixed norm multichannel image restoration algorithm. A functional which combines the least mean squares (LMS), the least mean fourth (LMF), and a smoothing functional using both withinand between-channel deterministic information is proposed. One parameter is defined to control the relative contribution between the LMS and the LMF norms, and...
