The Bayesian image retrieval system, PicHunter: Theory, implementation, and psychophysical experiments
- IEEE TRANSACTIONS ON IMAGE PROCESSING
, 2000
"... This paper presents the theory, design principles, implementation, and performance results of PicHunter, a prototype content-based image retrieval (CBIR) system that has been developed over the past three years. In addition, this document presents the rationale, design, and results of psychophysica ..."

of psychophysical experiments that were conducted to address some key issues that arose during PicHunter’s development. The PicHunter project makes four primary contributions to research on content-based image retrieval. First, PicHunter represents a simple instance of a general Bayesian framework we describe
Estimation of Separable Representations in Psychophysical Experiments
"... Studying how individuals compare two given quantita-tive stimuli, say d1 and d2, is a fundamental problem. One very common way to address it is through ratio magnitude estimation, that is to ask individuals not to give values to d1 and d2 but rather to give their es-timates of the ratio p = d1/d2. S ..."

. Several psychophysi-cal theories (the most known being Stevens ’ power-law) claim that this ratio cannot be known directly and that there are cognitive distortions on the apprehension of the different quantities. These theories result in the so-called separable representations (which include Stevens
Web-based vs. controlled environment psychophysics experiments

"... experiments, legibility, readability A recent trend in psychophysics experiments related to image quality is to perform the experiments on the World Wide Web with a large number of observers instead of in a laboratory under controlled conditions. This method assumes that the large number of particip ..."

Psychophysical experiments in a complex virtual environment
- Proc. of the Third PHANToM User Group Workshop
, 1998
"... We are using two PHANToM 3.0 force feedback devices in one workspace in order to perform studies of one-hand precision grip tasks or two handed pointing tasks. The visual environment is rendered by an Onyx workstation and presented in a specialized stereo head mounted display that allows eye trackin ..."

In addition, we are using free programmable force effects that depend on position or velocity information. Psychophysical experiments that simulate eye-hand coordination
Dynamic Range Compression by Differential Zone Mapping Based on Psychophysical Experiments
"... In this paper we present a new technique for the display of High Dynamic Range (HDR) images on Low Dynamic Range (LDR) displays. The described process has three stages. First, the input image is segmented into luminance zones. Second, the tone mapping operator (TMO) that performs better in each zone ..."

zone is automatically selected. Finally, the resulting tone mapping (TM) outputs for each zone are merged, generating the final LDR output image. To establish the TMO that performs better in each luminance zone we conducted a preliminary psychophysical experiment using a set of HDR images and six
A Psychophysical Experiment to Test the Efficient Stereo Coding Theory
"... . A theory of efficient stereo coding [2] predicts that, in a natural visual environment, where the ocular correlation of the input depends on stimulus orientations, the striate cortical cells are more likely binocular when selective to horizontal rather than vertical orientations. A psychophysi ..."

psychophysical experiment was designed to test this prediction. The interocular transfers of simultaneous orientation contrast at near horizontal and vertical orientations were measured. This measure was used to access the binocularity of the underlying cells. It turned out that in the natural stereovisual
Advanced modelling and preliminary psychophysical experiments for a free-hand haptic device
- In Proceedings of the 2006 IEEE/RSJ International Conference on Intelligent Robots and Systems
, 2006
"... Abstract-In this paper we report on a new improved free-hand haptic interface based on magnetorheological fluids (MRFs). MRFs are smart materials which change their rheology according to an external magnetic field. The new architecture here proposed results from the development and improvement of e ..."
