Many visual displays, such as movies and television, rely on sampling in the time domain. We
derive the spatiotemporal-frequency spectra for some simple moving images and illustrate …

The Image Systems Evaluation Toolkit (ISET) is an integrated suite of software routines that
simulate the capture and processing of visual scenes. ISET includes a graphical user …

We describe experimental tests of a spatial extension to the CIELAB color metric for measuring
color reproduction errors of digital images. The standard CIELAB /spl Delta/E metric is …

Image fidelity (inferred by the ability to discriminate between two images) and image quality (inferred
by the preference for one image over another) are often assumed to be directly …

We describe a simulation of the complete image processing pipeline of a digital camera,
beginning with a radiometric description of the scene captured by the camera and ending with a …

This paper describes a more efficient paired comparison method that reduces the number of
trials necessary for converting a table of paired comparisons into scaler data. Instead of …

Abstract Abstract: Abstract Vision researchers rely on visual display technology for the
presentation of stimuli to human and nonhuman observers. Verifying that the desired and …

As the number of imaging pixels in camera phones increases, users expect camera phone
image quality to be comparable to digital still cameras. The mobile imaging industry is aware, …

This report describes the spectral calibration of two digital color cameras, the Kodak DCS-200
and the Kodak DCS-420. We used previous work to model the output of the cameras in …

An experiment is described to obtain estimates of the spectral sensitivities of a digital image
capture device by photographing a wide range of input color signals. Given the red, green, …
