来源:[C].Image Quality Assessment Incorporating the Interaction of Spatial and Spectral Sensitivities of HVS2011Acta Press
摘要: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 ...

来源:[C].Super-Resolution of Text Images through Neighbor Embedding2011Acta Press
摘要:Single-image super-resolution (SISR) is the problem ofgenerating a high resolution (HR) image from a single low resolution (LR) image, possibly with the help of a set of training images. The SISR technique known as neighbor embedding (NE) is based on the assumption that correspon...

来源:[C].Fast Edge Preserving Smoothing Algorithm2011Acta Press
摘要:The identification of edges is a prerequisite in edge preserving image smoothing algorithms. It is, however, known that the more accurate the results need to be the more costly the calculation of the edges is. Edges are typically identified by the eigen analysis of the gradient m...

来源:[C].Constrained Gradient Integration for Improved Image Contrast2011Acta Press
摘要:The height from gradient algorithm proposed by Frankot and Chellappa has been employed as a solution to the gra- dient integration problem in both HDR compression and image to gray conversion. In both applications, the algo- rithm results in images that lack local contrast. In th...

来源:[C].Recognition of Blue Traffic Signs Enhanced by Aggregating Fragmentarily Segmented Sign Images2011Acta Press
摘要:This paper proposes a new algorithm for aggregating fragmented images to enhance the recognition of blue traffic signs designating directions. The system is designed for the assistance of safe driving. Subspace method and Histogram of Oriented Gradients (HOG) features are used fo...

来源:[C].Elimination of Color Distortion in High Dynamic Range Imaging using Channel Correlation2011Acta Press
摘要:High Dynamic Range(HDR) imaging technology can help us enlarge the ratio between the lightest and darkest pixel to contain more details of real life to enhance our visual effect. Many researchers proposed methods to generate HDR image with multiple exposures images. However, some...

来源:[C].Adaptive Video Streaming2011Acta Press
摘要:In this paper we present an approach for designing an adaptive video compression system that allows regions of interest to be identified and the picture size and quality configured to optimize performance for a system computation and communication capabilities. We present an...

来源:[C].Low Resolution Decoding for High-Efficiency Video Coding2011Acta Press
摘要:In this paper, we introduce a low resolution decoding framework in the context of the emerging high efficiency video coding standard (HEVC). Our goal is to provide a low power decoding option within a high resolution bit-stream for mobile or other power constrained devices. To f...

来源:[C].A Theoretical Framework for Perceptually Lossless Coding of Stereo 3-D Video2011Acta Press
摘要:In this conceptual paper, a theoretical framework is formulated and introduced to address the problem with application of a multichannel vision model based perceptual distortion measure to the rate-perceptual-distortion optimisation process for inter-frame and inter-view coding i...

来源:[C].Composite Video Noise Modelling and Suppressing2011Acta Press
摘要:In order to tackle the recording video denoising problem with non-stationary image contents, a critical task is toestimate statistical properties of the composite noise in video signals. After investigation of a variety of test videosequences, based on the wavelet decomposition o...
