The work of Penn State's Multidimensional Image Processing Laboratory spans many areas in the general field of imaging science: digital image processing, computer vision, scientific visualization, and virtual reality. We are particularly driven by problems in high-resolution 3D medical image processing, with a current focus on virtual endoscopy, image-guided endoscopy, and 3D Micro-CT analysis.
The laboratory has made numerous theoretical contributions to the general field of imaging science, including:
	1. image segmentation, region extraction, and edge detection.
	2. virtual endoscopy, volume visualization, and dynamic navigation
	3. video processing, registration, and tracking
	4. 3D-axes definition and path finding
	5. texture segmentation
	6. mathematical morphology
	7. image interpolation, enhancement, and filtering
Our current efforts are geared toward applying virtual endoscopy to 3D medical imaging problems. We are devising improved methods for lung-cancer assessment by applying the general concept of virtual bronchoscopy to 3D CT images. A significant part of this work involves video-endoscopic tracking and registration. We are also devising methods for analyzing large branching networks that appear in micro-CT images of the heart, liver, and other organs. Over 50 students have worked in the laboratory over the years.
