Aiming at several common drawbacks of existing gaze tracking algorithm which is based on image processing technology: low accuracy, low suitability and high requirement of device, this paper presents an improved gaze tracking method based on the human eye model. The vision scatter model is established by studying the relationship among the center of iris, inner corner of eye and the gaze direction...
Based on research on currently prevalent WEB application project attributes and analysis on the influence factors on development effort of the project, an estimation methodology based on page is present, in which, when the user WEB pages DEMO developed after requirements development, project effort can be estimated by evaluating pages' complexity and corresponding team productivity which can be obtained...
An approach to direction-of-arrival estimation for broadband coherent signals using constant beamwidth beamformers is proposed. A set of beamformers is designed using optimal array pattern synthesis method to realize constant beamwidth. The proposed beamspace DOA estimator maintain good DOA estimation and spatial resolution capability for the coherent signals.
