چکیده
In this paper we present a perceptual distortion mea sure that predicts image integrity far better than mean squared error This perceptual distortion measure is based on a model of human visual processing that ts empirical measurements of the psychophysics of spatial pattern de tection The model of human visual processing proposed involves two major components a steerable pyramid trans form and contrast normalization We also illustrate the usefulness of the model in predicting perceptual distortion in real images

Adaptive image coding with perceptual distortion control
This paper presents a discrete cosine transform (DCT)-based locally adaptive perceptual image coder, which discriminates between image components based on their perceptual relevance for achieving increased performance in terms of quality and bit rate. The new coder uses a locally adaptive perceptual quantization scheme based on a tractable perceptual distortion metric. Our strategy is to exploi...
متن کاملA Novel Image Compression Algorithm Based on Multitree Dictionary and Perceptual-based Rate-Distortion Optimization
This paper presents a novel block-based image coding algorithm which applies a tree-structured multitree dictionary and a perceptual-based rate distortion optimization scheme. While multitree dictionary is employed to support a very large number of different tilings, perceptual-based rate distortion optimization utilizes the SSIM metric, instead of popular MSE metric, to allocate bit rate accor...
متن کاملImage authentication using LBP-based perceptual image hashing
Feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. Simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of Local Binary Pattern features. In this paper, we investigate the use of local binary patterns for percep...
متن کاملWavelet-based image compression using perceptual distortion metric
In this paper, we have implemented a dithered quantization model to be used with perceptual distortion metric. Mean-square-error (MSE) based cost functions are mostly used for image coding. However, MSE does not necessarily preserve the perceptual quality of the original image. We are using Minkowsky metric as the criterion for allocating bits into various subbands to achieve desired degree of ...
متن کاملAttitudinal and perceptual factors in body image distortion: an exploratory study in patients with anorexia nervosa
BACKGROUND Body image disturbance is a core feature of anorexia nervosa (AN). Attitudinal and cognitive biases as well as fundamental perceptual differences have been hypothesized to play a role in this disturbance. METHOD This study investigated body image dissatisfaction and distortion, haptic perception and perfectionism in 30 patients with AN and 31 age-matched healthy controls. Participa...
