Abstract

This paper aims to present facial feature extraction by integrating 3 different sensors that might be used in the estimation of internal mental state. RGB-D camera is used at the pre and post monitoring phase while thermal infrared and visible camera is being used in the stimulus experiment. The measurement of three facial areas of sympathetic importance through purely imaging means that is periorbital, supraorbital and maxillary is done on the second stage. An Accurate and efficient thermal-infrared camera calibration is important for advancing computer vision research approach for geometrically calibrating individual and multiple cameras in both thermal and visible modalities. We also propose new printed Fever Cold Plaster (FCP) chessboard using a popular existing approach which is comparatively accurate and simple to execute. Based on the experiment conducted by comparing the degradation of image quality with the current approach, our proposed chessboard can be more clearly located than those on the applied standard chessboard by 39%.
