Resolution Enhancement of Color
نویسنده
چکیده
In this paper, an approach to improve the spatial resolution of color video is presented. Such high resolution images are desired, for example, in video printing. Previous work has shown that the most important step in achieving high quality results is the accuracy of the motion eld. It is well known that motion estimation is an ill-posed problem. However, in processing color video, additional information contained in the color channels may be used to improve the accuracy of the motion eld over the motion eld obtained with the use of only one channel. In turn, this improvement in the motion eld will be shown through several experimental results to signiicantly improve the estimation of a high resolution image sequence from a corresponding observed low resolution sequence.

A 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 کاملColor Super-Resolution from a Single CCD
Limitation in the resolution of CCD image sensors has provided motivation to enhance the resolution of images. Super-resolution has been applied mainly to grayscale images, and producing a high-resolution color image from a single CCD sensor has not been discussed thoroughly. This work aims at producing a high-resolution color image directly from ”color mosaic” images obtained by a singleCCD wi...
