Halftoning is the core algorithm governing most digital printing or imaging devices, by which images of continuous tones are converted to ensembles of discrete or quantum dots. It is through the human vision system (HVS) that such fields of quantum dots can be perceived almost identical to the original continuous images. In the current work, we propose a leastsquare based halftoning model with ...
The development of reliable objective image quality assessment (IQA) metrics coordinate to the human‟s perception is crucial in numerous image processing applications. State-of-art perceptual IQA methods focus on two techniques using the sensitivities of human visual system (HVS). One is perceptual pooling strategy in spatial domain while the other is multi-channel model in spectral domain. In ...
Intellectual property protection of deep neural networks is receiving attention from more and researchers, the latest research applies model watermarking to generative models for image processing. However, existing methods designed do not take into account effects different channels sample images on watermarking. As a result, performance still limited. To tackle this problem, in paper, we first...
This paper proposes a novel face recognition algorithm inspired by Human Visual System (HVS). Firstly, we learn where people look by recording observers’ eye movements when they are viewing face images. We find that the observers are consistent in the regions fixated and such fixated regions are selected as the salient regions. Secondly, we represent the face images by four scales of Local Bina...
A semantic parser based on the hidden vector state (HVS) model has been proposed for extracting protein-protein interactions. The HVS model is an extension of the basic discrete hidden Markov model, in which context is encoded as a stack-oriented state vector and state transitions are factored into a stack shift operation followed by the push of a new preterminal category label. In this paper, ...
It has been often stated that the overall pattern of human maternal lineages in Europe is largely uniform. Yet this uniformity may also result from an insufficient depth and width of the phylogenetic analysis, in particular of the predominant western Eurasian haplogroup (Hg) H that comprises nearly a half of the European mitochondrial DNA (mtDNA) pool. Making use of the coding sequence informat...
زمینه و هدف: ژنوم میتوکندری سلول های انسانی دارای 16569 نوکلئوتید می باشد که توالی و ساختار آن در سال1981 تعیین شده و دگرگونی های ایجاد شده در ناحیه توالی بسیار کوتاه یک (HVS-1) ده برابر سریع تر از DNA کروموزومی است. هدف از این تحقیق مطالعه میزان پلی مرفیسم، تعیین درصد موتاسیون و میزان هموپلاسی در اقوام مختلف ایرانی، بررسی میزان فراوانی هاپلوگروپ ها و محاسبه حداقل و حداکثر گوناگونی در هاپلوتیپ ...
Abstract Background Tricuspid regurgitation (TR) is frequent among patients with severe left-sided valvular heart disease (LS-VHD). Objectives This study sought to assess TR frequency, management and outcome in this population. Methods Among 6883 LS-VHD or previous intervention the EURObservational Research Programme prospective VHD II survey, we analyzed frequency grade of according LS-VHD, 6-...
Several human visual system (HVS) based quality metrics have been developed in recent years to measure the quality distortions caused by digital image coding techniques. Because of the complicated nature of the HVS characteristics, these metrics do not provide acceptable correlation with perceptual evaluations of the distortion. Recent studies by the Visual Quality Experts Group (VQEG) also sho...
