Abstract
The current work undertakes the measurement of the thresholds for the visual detedction of the Frazier-Jawerth Transform (FJT) basis functions. These results will be used in the development of a psychovisually-based quantizer. The thresholds were determined by the use of psychovisual observer excperiments. It is shown that the detectability of the basis functions is in accord with current knowledge of the spatial frequency sensitivity of the human visual system. Corrected values, however, imply that the FJT quantizer may not match the properties of ordinary images as well as the psychovisual quyantizers used for such menthods as the discrete cosine transform.
