This paper gives an overview of a system for robustly tracking the 3D position and orientation of a finger using a few closely spaced cameras. Accurate results are obtained by combining features of stereo range images and color images. This work also provides a design framework for combining multiple sources of information, including stereo range images, color segmentations, shape information a...

For the linear discrimination of two stimuli in white Gaussian noise in the presence of internal noise, a method is described for estimating linear classification weights from the sum of noise images segregated by stimulus and response. The recommended method for combining the two response images for the same stimulus is to difference the average images. Weights are derived for combining images...
