Maximum likelihood difference scaling of image quality in compression-degraded images.
Lossy image compression techniques allow arbitrarily high compression rates but at the price of poor image quality. We applied maximum likelihood difference scaling to evaluate image quality of nine images, each compressed via vector quantization to ten different levels, within two different color spaces, RGB and CIE 1976 L*a*b*. In L*a*b* space, images could be compressed on average by 32% mor...
متن کاملMaximum likelihood difference scaling.
We present a stochastic model of suprathreshold perceptual differences based on difference measurement. We develop a maximum likelihood difference scaling (MLDS) method for estimating its parameters and evaluate the reliability and distributional robustness of the fitting method. We also describe a method for testing whether the difference measurement model is appropriate as a description of hu...
متن کاملMLDS: Maximum Likelihood Difference Scaling in R
This introduction to the R package MLDS is a modified and updated version of Knoblauch and Maloney (2008) published in the Journal of Statistical Software. The MLDS package in the R programming language can be used to estimate perceptual scales based on the results of psychophysical experiments using the method of difference scaling. In a difference scaling experiment, observers compare two sup...
متن کاملRestoration of Degraded Images with Maximum Entropy
Images recorded in electronic or photographic media are often degraded due to system imperfections such as diffraction effects, optical system aberrations, camera and/or object motions, defocussing, or atmospheric turbulences. In addition to these blurring effects, the recorded image is usually corrupted by various random noise effects such as the randomness of the film grain, photoelectric eff...
متن کاملMaximum-Likelihood Image Matching
ÐImage matching applications such as tracking and stereo commonly use the sum-of-squared-difference (SSD) measure to determine the best match. However, this measure is sensitive to outliers and is not robust to template variations. Alternative measures have also been proposed that are more robust to these issues. We improve upon these using a probabilistic formulation for image matching in term...
