The fusion of 3D freehand ultrasound with CT and CTA has benefits for a variety of clinical applications, however a lot of manual work is usually required for correct registration....
This paper gives a practical and accurate algorithm for the computation of the quadrifocal tensor and extraction of camera matrices from it. Previous methods for using the quadrifo...
A temporally scalable video coding algorithm allows extraction of video of multiple frame rates from a single coded stream. This paper compares the rate-distortion performance of ...
Chromatic aberration is the phenomenon where lights of different wavelengths fail to converge at the same position on the focal plane. There are two kinds of chromatic aberration:...
