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...
The medical image has become a diagnostic technique largely applied for the determination of doctor's diagnosis. But it is difficult for detecting the medical image borders accurately. This paper proposes a new medical image edge-detection technique based on PSO Algorithm. A new fitness function is formulated as the objective function. PSO algorithm is adopted to find the optimal filter mask to enhance...
Measurement of hydrophobicity is not only a main way to evaluate the performance of insulators, but also an important factor to ensure the safety of insulators.A novel hydrophobic measurement algorithm based on information fusion technology is proposed in this paper. By the triangle module operator, the membership function of area ratio and shape factor are fused together to classify the hydrophobicity...
Accuracy of single filter used in most of vehicle navigation decreases when system state is both linear and nonlinear. According to the output state of the receiver to choose linear or nonlinear filter, a kind of combined filtering structure is proposed. Furthermore, a derivative-free filter is adopted as nonlinear filter, especially, formulas of state and random noise covariance matrix's Cholesky...
