A Wavelet Visible Difference Predictor - Image Processing, IEEE Transactions on
In this paper, we describe a model of the human visual system (HVS) based on the wavelet transform. This model is largely based on a previously proposed model, but has a number of modifications that make it more amenable to potential integration into a wavelet based image compression scheme. These modifications include the use of a separable wavelet transform instead of the cortex transform, th...
متن کاملVideo Quality Evaluation Based on Wavelet Visible Difference Measure
In this paper, we propose a visual quality evaluation method based on visible error between original and distorted images using wavelet just-noticeabledistortion (JND) profile. The error below visual thresholds in each frequency bands is ignored while some errors that take place in the content-activity regions are masked. By measuring the visible differences of two inputs and visual masking a q...
متن کاملA visible difference
Thirty years ago I was a young postdoc working with Larry Weiskrantz at the Department of Experimental Psychology in Oxford. The laboratory (or cubbyhole) where I worked was some distance from the main department and, perhaps because of this, our little group of postdocs and graduate students developed a strong sense of camaraderie. We spent many of our lunch hours arguing science, politics and...
متن کاملDifference Wavelet — Theory and a Comparison Study
Wavelet methods with polynomial filters are usually favored in applications for their fast wavelet transforms and compact support. However, wavelet methods with rational filters have more freedom to achieve smaller condition numbers, more regularity and better efficiency. Such methods can be attractive if they also possess fast algorithms and have fast decay (as if the corresponding wavelets ha...
متن کاملImproved Visible Differences Predictor Using a Complex Cortex Transform
Prediction of visible differences involves modeling of the human visual response to distortions in the image data. Following the approach of Daly [1], this paper introduces several algorithm improvements allowing for more accurate calculation of threshold elevation and modeling of the facilitation effect during phase-coherent masking. This is achieved by introducing a complex-valued cortex tran...
