Motion Analysis for Image Enhancement: Resolution, Occlusion, and Transparency
نویسندگان
چکیده
Accurate computation of image motion enables the enhancement of image sequences. In scenes having multiple moving objects the motion computation is performed together with object segmentation by using a unique temporal integration approach. After computing the motion for the di erent image regions, these regions can be enhanced by fusing several successive frames covering the same region. Enhancements treated here include improvement of image resolution, lling-in occluded regions, and reconstruction of transparent objects.

Image sequence enhancement using multiple motions analysis
Accurate computation of image motion enables the enhancement of image sequences. Motion computation in scenes having multiple moving objects is performed together with object segmentation by using a unique temporal integration approach. Having accurate motion estimation for image regions, these regions can be enhanced by fusing all successive frames covering the same region. Enhancement include...
متن کاملPseudo Zernike Moment-based Multi-frame Super Resolution
The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...
متن کاملA Deep Model for Super-resolution Enhancement from a Single Image
This study presents a method to reconstruct a high-resolution image using a deep convolution neural network. We propose a deep model, entitled Deep Block Super Resolution (DBSR), by fusing the output features of a deep convolutional network and a shallow convolutional network. In this way, our model benefits from high frequency and low frequency features extracted from deep and shallow networks...
متن کاملLocal orientation analysis in images and image sequences using steerable filters
In this thesis, we address the issue of local orientation analysis using steerable filters. From the standpoint of the sampling theory, current orientation steerable filters sample the spectrum of the orientation space with Dirac functions. According to the well known uncertainty principle, we cannot simultaneously localize a signal both in the spatial domain and in the spectral domain exactly....
متن کاملMultiple motion analysis: in spatial or in spectral domain?
In this paper, we compare the effects of multiple motions in spatial and spectral representations of an image sequence. We describe multiple motions in both domains and establish a comparison regarding their inherent properties when discretized. Though the spectral model provides us with an explicit description of both occlusion and transparency, it turns out that its resolution is very limited...
