A loudness balancing process includes three operations. In a first operation, the user specifies a plurality of digitally sampled audio time domain waveforms and an adjusted maximum loudness for each waveform is generated and stored. This operation i

Colors sampled in an array of pixels were converted into various luminance-chrominance representations, and the chrominance values were spatially subsampled to achieve a compression of the data. For viewing, the chrominance values were reinterpolated

The threshold elevation for a sinusoidal grating of 13.3 c/deg is significantly less for adaptation to a sum of 10.7 and 8 c/deg or 13.3 and 8 c/deg than for adaptation to 10.7 or 13.3 alone. This poses severe problems for any theory of independent s

Prolonged adaptation to red convex and green concave curves results in an aftereffect of the opposite color on test patterns composed of convex and concave arcs. This result has recently been ascribed to the adaptation of curvature detectors in the h

The amount of information required to store color images is immense. For a typical 1024×1024 pixel color image, 8 bits each of R, G, and B data are usually stored (to avoid luminance or chromatic contouring artifacts), which adds up to 3 Mbytes per

The Pi-4 color mechanism was isolated in three observers with a 500-nm, 200-msec, l-deg foveal test flash. Stiles's field displacement law was tested with increment thresholds upon monochromatic adapting fields of several wave-lengths. The data of al
