摘要：
Psychophysical studies of the visual perception of incomplete contour images have been carried out. The images were synthesized by means of wavelets. The wavelets consisted of the difference-of-Gaussians (DoG) function and oriented wavelets whose spectrum is limited both in the frequency range and in the orientation range. The image size and the number and angular size of the wavelets were varied. The dependence between the characteristics of the wavelets and the recognition thresholds of the incomplete images was established. (C) 2011 Optical Society of America.
