Abstract

This chapter describes the model of attention-guided visual perception and recognition previously published in Vision Research. The model contains (1) a low-level subsystem that performs a fovealike transformation and detection of primary features (edges) and (2) a high-level subsystem that includes separated “what” (sensory memory) and “where”(motor memory) subsystems. In the model, image recognition occurs under top-down control of visual=attention during the execution of a behavioral recognition program formed during the primary viewing of the image. The recognition program contains both programmed movements of an attention window (stored in the motor memory) and predicted image fragments (stored in the sensory memory) for each consecutive fixation. The model shows the ability to recognize complex images invariantly with respect to shift, rotation, and scale.
