The design of an industrial pipe inspection robot for 4" firewater piping inspection and mapping with some new and unreported features is presented. The robot consists of a compact 3D MEMs Lidar with non-linear scanning pattern in the form of Lissajous trajectories that produces a dense scan of inne…
In this paper, a robust sequential dictionary learning (DL) algorithm is presented. It is obtained by using a robust loss function in the data fidelity term of the DL objective instead of the usual quadratic loss. The proposed robust loss function is derived from the α-divergence as an alternative t…
Dictionary learning algorithms have been successfully applied to a number of signal and image processing problems. In some applications however, the observed signals may have a multi-subpsace structure that enables block-sparse signal representations. Based on the observation that the observed signa…
In recent years, data driven methods have been successfully used for analyzing multi-subject functional magnetic resonance imaging (fMRI) datasets. These methods attempt to learn shared spatial activation maps (SM) or voxel time courses (TC) from temporally or spatially concatenated fMRI datasets re…
In recent history, dictionary learning (DL) methods have been successfully used for analyzing multi-subject functional magnetic resonance imaging. These algorithms try to learn group-level spatial activation maps (SM) or voxel time courses (TC) from temporally or spatially concatenated fMRI datasets…
Traditional Simultaneous Localization and Mapping (SLAM) approaches build maps based on points, lines or planes. These maps visually resemble the environment but without any semantic or information about the objects in the environment. Recent advancements in machine learning have made object detecti…
Multiple-set canonical correlation analysis (mCCA) is a generalization of canonical correlation analysis (CCA) to three or more sets of variables. It aims to study the relationships between several sets of variables and it subsumes a number of interesting multivariate data analysis techniques as spe…
