Perceptually relevant image fidelity

چکیده
In recent years a number of image delity measures have been developed. These measures are designed to predict a person's ability to perceive di erences between two nearly identical images. Successful image delity measures allow digital imaging developers to replace di cult and time consuming subjective evaluations with automated evaluations. Although a number of image delity measures have been developed, no method for evaluating and comparing the accuracy of these measures has been commonly accepted. In this paper we describe a new method for evaluating image delity measures. The method involves comparing spatially localized ratings from a human subject with distortion maps generated by an image delity measure.

DWT based Digital Watermarking Fidelity and Robustness Evaluation
An Image AdaptiveWatermarking method based on the Discrete Wavelet Transform is presented in this paper. The robustness and fidelity of the proposed method are evaluated and the method is compared to state-of-the-art watermarking techniques available in the literature. For the evaluation of watermark transparency, an image fidelity factor based on a perceptual distortion metric is introduced. O...
متن کاملPerformance evaluation of objective quality metrics for HDR image compression
Due to the much larger luminance and contrast characteristics of high dynamic range (HDR) images, wellknown objective quality metrics, widely used for the assessment of low dynamic range (LDR) content, cannot be directly applied to HDR images in order to predict their perceptual fidelity. To overcome this limitation, advanced fidelity metrics, such as the HDR-VDP, have been proposed to accurate...
متن کاملStructured Image Techniques for Efficient High-Fidelity Graphics
Global illumination rendering in real-time for high-fidelity graphics remains one of the biggest challenges for computer graphics in the foreseeable future. Recent work has shown that significant amounts of time can be saved by selectively rendering in high quality only those parts of the image that are considered perceptually more important. Regions of the final rendering that are deemed more ...
متن کاملVisual Fidelity of Image Based Rendering
This paper focuses on factors which influence the fidelity, or realness, of images created by image based rendering (IBR) methods. First, we address the issue of large memory requirements of IBR techniques and we analyze necessary number of input images for a scene representation preserving visual fidelity of the output images. Then, we investigate optimal scaling producing output images that a...
متن کاملRelevance of human vision to JPEGDCT compression
This paper asks how the vision community can contribute to the goal of achieving perceptually lossless image fidelity with maximum compression. In order to maintain a sharp focus the discussion is restricted to the JPEG-DCT image compression standard. The numerous problems that confront vision researchers entering the field of image compression are discussed. Special attention is paid to the co...
