An Indoor Positioning Approach Based on Fusion of Cameras and Infrared Sensors
Sensors, 2019 A method for infrared and cameras sensor fusion, applied to indoor positioning in intelligent spaces, is proposed in this work. The fused position is obtained with a maximum likelihood estimator from infrared and camera independent observations. Specific

British Journal of General Practice, 2013 Photography has been used extensively in medicine since the 19th century, and now the universal availability of the digital camera has made the recording of images, archiving, and their transmission over the internet straightforward. When downloaded onto the practice computer, pristine images can, at the touch of a few keys, appear and can be used not ...
