    Low-Cost Super-Resolution Algorithms Implementation Over a HW/SW Video Compression Platform

    Two approaches are presented in this paper to improve the quality of digital images over the sensor resolution using super-resolution techniques: iterative super-resolution (ISR) and noniterative super-resolut...

    A Bayesian Super-Resolution Approach to Demosaicing of Blurred Images

    Most of the available digital color cameras use a single image sensor with a color filter array (CFA) in acquiring an image. In order to produce a visible color image, a demosaicing process must be applied, wh...

    A Fast Algorithm for Image Super-Resolution from Blurred Observations

    We study the problem of reconstruction of a high-resolution image from several blurred low-resolution image frames. The image frames consist of blurred, decimated, and noisy versions of a high-resolution image...

    Adaptive Outlier Rejection in Image Super-resolution

    One critical aspect to achieve efficient implementations of image super-resolution is the need for accurate subpixel registration of the input images. The overall performance of super-resolution algorithms is ...

    Robust Fusion of Irregularly Sampled Data Using Adaptive Normalized Convolution

    We present a novel algorithm for image fusion from irregularly sampled data. The method is based on the framework of normalized convolution (NC), in which the local signal is approximated through a projection ...

    Improving a Single Down-Sampled Image Using Probability-Filtering-Based Interpolation and Improved Poisson Maximum A Posteriori Super-Resolution

    We present a novel hybrid scheme called "hyper-resolution" that integrates image probability-filtering-based interpolation and improved Poisson maximum a posteriori (MAP) super-resolution to respectively enhan...

    Video-to-Video Dynamic Super-Resolution for Grayscale and Color Sequences

    We address the dynamic super-resolution (SR) problem of reconstructing a high-quality set of monochromatic or color super-resolved images from low-quality monochromatic, color, or mosaiced frames. Our approach...
