Abstract

A digital image display based system was designed and implemented to perform visual measurements of apparent modulation induced by the Cornsweet illusion. The system was used to examine the results reported on previous experiments designed to measure the modulation transfer function of the human visual system. The reported results of experiments performed by Dooley and Greenfield on induced modulation were examined, and data not reported in that work was collected on the range of modulations over which observers perceived linear images. The system developed has the flexibility to be adapted for many different types of experiments. Visual experiments involving human observers reported in the literature often required the construction of specialized, complex mechanical devices to collect data about the visual system. In contrast, the system described here can be easily adapted for a broad range of experiments . In addition to the Cornsweet perception study described, the system was configured to study an experiment performed by Lowry and DePalma involving the perception of Mach Bands.
