Super-Resolution Image Reconstruction Based on Guidance Image
Super-resolution framework uses multiple noisy low resolution images from camera to generate a higher resolution image that has better spatial resolution than any of the available low resolution images. Super-resolution is an ill-posed problem. A inherent difficulty is the challenge of inverting the image observation model without amplifying the effect of noise in the measured data. Classically...
متن کاملMulti-resolution Image Authentication Watermarking Based on Progressive Image Transmission
In this paper, a watermarking for multi-resolution image authentication is proposed. The most important image content with progressive characteristic is taken as the authentication code. The authentication code is then embedded/extracted according to multi-resolution image coding. The experimental results show the validity of the proposed scheme. The significant tampering can be detected firstl...
متن کاملSuper-resolution Based Image Inpainting
-This paper introduces a new examplar-based inpainting framework. A coarse version of the input image is first inpainted by a non-parametric patch sampling. Compared to existing approaches, some improvements have been done (e.g. filling order computation, combination of K nearest neighbours). The inpainted of a coarse version of the input image allows to reduce the computational complexity, to ...
متن کاملImage Sequence Super-resolution based on Learning using Feature Descriptors
There is currently a growing demand for high-resolution images and videos in several domains of knowledge, such as surveillance, remote sensing, medicine, industrial automation, microscopy, among others. High resolution images provide details that are important to tasks of analysis and visualization of data present in the images. However, due to the cost of high precision sensors and the limita...
متن کاملImage Super-Resolution Reconstruction Based On L1/2 Sparsity
Based on image sparse representation in the shearlet domain, we proposed a 2 1 L sparsity regularized unconvex variation model for image super-resolution. The 2 1 L regularizer term constrains the underlying image to have a sparse representation in shearlet domain. The fidelity term restricts the consistency with the measured imaged in terms of the data degradation model. Then, the variable spl...
