Integration of stereo video into Slicer3

Objective

The objective of this study is to grab and visualize video images in Slicer3 as soon as they are acquired. The source of the video can be laparoscope or ultrasound for my project. However, generally the video source can be any modality capable of streaming out the video. Actually, I plan to integrate laparascope images and intra-operative ultrasound with preoperative MR image. In order to present the video in right position with respective to pre-operative MR, we need to track the laparoscope camera and ultrasound transducer. Therefore, camera calibration and ultrasound calibration should be added to the slicer in the long run.

Approach, Plan

Real-time video grabbing and visualization have been implemented previously for the ultrasound in [AtamiViewer]. However, this time I am trying to do that in Slicer3. Up to now, I studied two possible alternatives so as to tackle video grabbing in Slicer3. The first possible approach was using a IGSTK library containing a VideoImager (http://public.kitware.com/IGSTKWIKI/index.php/VideoGrabber_classes). Actually, since the code is recently developed and is currently under review by Andinet Enquobahrie. He believes that the code is not at the stage so that it can be used for Slicer3.

Progress

I Studied Everything but implemented nothing. :-(
