Focus Assessment Method of Gaze Tracking Camera Based on ε-Support Vector Regression

In order to capture an eye image of high quality in a gaze-tracking camera, an auto-focusing mechanism is used, which requires accurate focus assessment. Although there has been previous research on focus assessment in the spatial or wavelet domains, there are few previous studies that combine all o...
