• Basic Research
• Our research is to deal with situations when we want very high accuracy of reconstruction from data that might have up to 95% noise. This research extends from two view geometry to multi-view geometry in computer vision and is general enough to be applied in any data-mining and machine learning application. Even randomized approximation algorithm like RANSAC for NP hard matching problem would require billions of iterations to meet 99% accuracy in such heavy noise and so cannot be brought into practice. Our task is to accomplish this in manageable iterations or time so that reliable 3D reconstructive geometry can be made practical over devices as common as mobile cameras. This goal lead us to
