Blind image deblurring aims to recover sharp from a blurred one while the blur kernel is unknown. To solve this ill-posed problem, great amount of priors have been explored and employed in area. In paper, we present blind method based on Local Maximum Gradient (LMG) prior. Our work inspired by simple intuitive observation that maximum value local patch gradient will diminish after process, which proved be true both mathematically empirically. This inherent property process helps us establish...

Recent studies in deepfake detection have yielded promising results when the training and testing face forgeries are from same dataset. However, problem remains challenging one tries to generalize detector created by unseen methods This work addresses generalizable a simple principle: representation should be sensitive diverse types of forgeries. Following this principle, we propose enrich "diversity" synthesizing augmented with pool forgery configurations strengthen "sensitivity" enforcing...

Deep learning is well known as a method to extract hierarchical representations of data. In this paper novel unsupervised deep based methodology, named Local Binary Pattern Network (LBPNet), proposed efficiently and compare high-level over-complete features in multilayer hierarchy. The LBPNet retains the same topology Convolutional Neural (CNN) - one most studied architectures whereas trainable kernels are replaced by off-the-shelf computer vision descriptor (i.e., LBP). This enables achieve...

Recently, deep learning has been successfully applied to the single-image super-resolution (SISR) with remarkable performance. However, most existing methods focus on building a more complex network large number of layers, which can entail heavy computational costs and memory storage. To address this problem, we present lightweight Self-Calibrated Efficient Transformer (SCET) solve problem. The architecture SCET mainly consists self-calibrated module efficient transformer block, where adopts...

We are dealing with the face cluster recognition problem where there multiple images per subject in both gallery and probe sets. It is never guaranteed to have a clear spatio-temporal relation among of each subject. Considering that image vectors subject, either or probe, span subspace, an algorithm, Dual Linear Regression Classification (DLRC), for developed distance between two subspaces defined as similarity value DLRC attempts find "virtual" located intersection spanning from clusters...

Blind deblurring has received considerable attention in recent years. However, state-of-the-art methods often fail to process saturated blurry images. The main reason is that pixels around regions are not conforming the commonly used linear blur model. Pioneer arts suggest excluding these during process, which sometimes simultaneously removes informative edges and results insufficient information for kernel estimation when large exist. To address this problem, we introduce a new model fit...

Content distribution, especially the distribution of video content, unavoidably consumes bandwidth resource heavily. Internet content providers (ICP) spend lots money to buy network (CDN) service. By deploying thousands edge servers close end users, CDN companies are able distribute efficiently. In lieu traditional systems, we implement a crowdsourcing-based system, Thunder Crystal, which utilizes agents' upload amplify capacity. Agents well motivated contribute storage and system by rebated...

Since deep convolutional neural network (CNN) has achieved excellent results in single image super-resolution (SISR), an increasing number of methods based on CNN have been proposed. Most CNN-based are devoted to finding mapping pixel intensity while ignoring the importance frequency information, which can reflect semantic information images different bands. This leads less effectiveness reconstruction high-frequency details. To address this problem, we propose a novel method named joint...
