The wound care management of bedsore is important to long-term bedridden patients. The wound size is usually monitored by a consumer-graded camera and then calculated by computer-aided analysis. In this paper, we simulated a subcutaneous and dermal injury using vacuum cupping experiment and performed multispectral imaging with three wavelengths, including active 650 nanometers red light and 940 nanometers...
In this paper, we proposed a novel and simple gaze calibration procedure, namely Pattern Voting Scheme (PVS), for reducing the computing complex. The proposed method doesn't require multiple spatial coordinates to estimate the inner and outer parameters of the camera and without regard to the evaluation of accuracy. The iris location can be determined easy by using the voting weight. The PVS is a...
