@article { , title = {Ptu-024 - photometric stereo reconstruction for surface analysis of mucosal tissue}, abstract = {This paper provides a novel approach for real-time detection of polyps. Using a photometric stereo sensor for endoscopy imaging in a porcine model, the 3D surface geometry of a porcine gut is recovered. Shape features are extracted from the 3D surface data and analysed to detect and identify regions that are locally spherical, suggestive of polyps to aid polyp detection.}, issn = {0959-8138}, issue = {1}, journal = {BMJ}, pages = {68-69}, publicationstatus = {Published}, publisher = {BMJ Publishing Group}, url = {https://uwe-repository.worktribe.com/output/832617}, volume = {64}, keyword = {Centre for Machine Vision, 3D surface recovery, photometry stereo, 3D endoscopy, shape index mapping, polyps detection, real-time diagnosis}, year = {2015}, author = {Poullis, Andy and Groves, Chris and Slabaugh, Greg and Emrith, Khemraj and Smith, Melvyn} }
