Neuromorphic Event-Based Generalized Time-Based Stereovision

Abstract 3D reconstruction from multiple viewpoints is an important problem in machine vision that allows recovering tridimensional structures from multiple two-dimensional views of a given scene. Reconstruction from multiple views is conventionally achieved through a process of pixel luminance-based matching between different views. Unlike conventional machine vision methods that solve matching ambiguities by operating only on spatial constraints and luminance, …

Event-Based 3D Motion Flow Estimation Using 4D Spatio Temporal Subspaces Properties

Abstract State of the art scene flow estimation techniques are based on projections of the 3D motion on image using luminance—sampled at the frame rate of the cameras—as the principal source of information. We introduce in this paper a pure time based approach to estimate the flow from 3D point clouds primarily output by neuromorphic event-based stereo camera rigs, or …


Event-based 3D reconstruction from neuromorphic retinas

Abstract This paper presents a novel n-ocular 3D reconstruction algorithm for event-based vision data from bio-inspired artificial retina sensors. Artificial retinas capture visual information asynchronously and encode it into streams of asynchronous spike-like pulse signals carrying information on, e.g., temporal contrast events in the scene. The precise time of the occurrence of these visual features are implicitly encoded in the …

Asynchronous Event-Based 3D Vision

Abstract Reproducing biological vision in a machine is a challenging problem for which scientists have just scratched the surface. Living organisms are able to per- form complex tasks in an awestruckly efficient manner. The stereovision is one of these complex mechanisms that computer scientists try to replicate with high resolution cameras. This thesis takes on the stereovision problem in a …
