A new method of calibration is proposed for active visual sensing for use in 3D analysis. The method, based on an adaptation of the two-camera plane model, permits the calibration of a mobile camera as a function of the position and orientation of the came ...
A new method of camera calibration is proposed for active visual sensing for use in 3D scene analysis. The method, based on a variation of the two plane camera model, permits the calibration of a mobile camera as a function of the position and orientation ...
By combining a metallic ink and standard inks, one may create printed images having a dynamic appearance: an image viewed under specular reflection may be considerably different from the same image viewed under non-specular reflection. Patterns which are e ...
A non-invasive method to measure the optical properties of a turbid medium such as biological tissue is described. To determine the absorption and reduced scattering coefficient, the sample is illuminated with spatially intensity modulated light and the ba ...
The invertibility of linear periodically time-varying (LPTV) filters is addressed. A necessary and sufficient condition under which a LPTV filter can be inverted is shown using a LPTV postfilter. Such techniques find application, for example, in aliasing c ...
