An Embedded System For An Eye-Detection Sensor

Current commercial and explore systems use software instruction execution and require a dedicated computer for the range of mountains- affect taska large, expensive, and complicated-to-use solution. In put in to make eye-gaze tracking ubiquitous, the system compl exity, size, and terms must be substantially reduced. This paper presents a hardware-based embed system for eye detection, implemented using simple consistent system gates, with no CPU and no addressable kind bu?ers. The interpret-processing algorithmic rule was redesigned to enable highly parallel, single-pass image-processing implementation.

A model system uses a CMOS digital imaging sensor and an FPGA for the image processing. It processes 640 · 480 progressive run over frames at a 60 fps rate, and outputs a compact appoint of sub- pixel accurate (x, y) eye coordinates via USB communication. experiment with detection of human eyes and synthetic targets are reported. This imma ture logic design, operating at the sensorÕ! s pixel clock, is suitable for single-chip eye detection and eye-gaze tracking sensors, thus reservation an important step towards press production, low cost systems.
