Depth From Motion and Optical Blur With an Unscented Kalman Filter
C. Paramanand,A. N. Rajagopalan +1 more
TL;DR: This paper proposes and develops a formulation of unscented Kalman filter for depth estimation, and addresses a special and challenging scenario of depth from defocus with translational jitter.
Journal ArticleDOI
Shape from Sharp and Motion-Blurred Image Pair
C. Paramanand,A. N. Rajagopalan +1 more
TL;DR: This work develops a technique to estimate the transformation spread function (TSF) which symbolizes the camera shake and recovers the complete depth map of the scene within a regularization framework using an unblurred–blurred image pair.
Proceedings ArticleDOI
Unscented transformation for depth from motion-blur in videos
C. Paramanand,A. N. Rajagopalan +1 more
TL;DR: It is shown that the relationship between the observation and the scale factor of the motion-blur kernel associated with the depth at a point is nonlinear and the use of the unscented Kalman filter for state estimation is proposed.
Proceedings ArticleDOI
Motion blur for motion segmentation
C. Paramanand,A. N. Rajagopalan +1 more
TL;DR: This paper develops a method for motion segmentation using blur kernels to segment them according to their relative motion using transformation spread functions (TSFs) which represent the relative motions.
Journal ArticleDOI
Image matching with higher-order geometric features
C. Paramanand,A. N. Rajagopalan +1 more
TL;DR: A geometric matching technique in which line segments and elliptical arcs are used as edge features and the use of these higher-order features renders feature representation efficient.
