A New Approach to Measuring Image Quality via Frequency Analysis - Lorenzetto (Correct)
....especially expensive when observers need to be trained before they can be used in studies. Maintaining exactly the same conditions for all observers is also extremely dicult and expensive. 2.1. 2 Con rming Image Quality Hearty s article entitled Achieving and Con rming Optimum Image Quality [4] describes his main concern as optimizing compression tools for television images. The task of compressing an image with minimum quality loss is broken into two complementary techniques. These are 1. Perceptual Models and Data. He considers the importance of accounting for shifts in gaze during ....
....propose a method to overcome some of the faults inherent to the root mean square (RMS) and signal to noise ratio (SNR) errors. These errors only incorporate tallies of pixel di erence. No information about location or intensity of pixel values is included in the resulting error. Both Hearty [4] and Daly [2] agree, stating that the RMS and SNR errors are inaccurate predictors of perceptual distortion (perceptual distortion is discussed further in Chapter 3) To overcome these problems, Wilson et al. propose a new measure g based on the measure developed by Baddeley [15] for binary ....

Image Comparison Metrics: A Review - Lorenzetto (1998) (Correct)
....al. propose a method that will overcome some of the faults with the root mean square (RMS) and signal to noise ratio (SNR) errors. These errors only incorporate tallies over pixel di erences. No information about location or intensity of pixel values is included in the resulting error. Both Hearty [2] and Daly [1] agree, stating that the RMS and SNR errors are inaccurate predictors of perceptual distortion. To overcome these problems, Wilson et al. propose a new measure g based on the measure developed by Baddeley [6] for binary image comparison. The measure is based on a myopic ....

However no formal results are mentioned. 4. 2 Con rming Image Quality Hearty s article entitled Achieving and Con rming Optimum Image Quality [2] describes his main concern with optimizing compression tools for television images.
