چکیده

Up to date several strategies of how to retrieve disparity information from a sequence of images have been described. In this paper we introduce a method to retrieve disparity based on motion and stereovision. A motion representation in form of a bidimensional motion charge map, based in the so-called permanency memories mechanism is presented. For each pair of frames of a video stereovision sequence, the method displaces the left permanency stereomemory on the epipolar restriction basis over the right one, in order to analyze the disparities of the motion trails cal-

Stereovision depth analysis by two-dimensional motion charge memories

Up to date several strategies of how to retrieve depth information from a sequence of images have been described. In this paper a method that turns around the symbiosis existing between stereovision and motion is introduced. The central idea behind our approach is to transpose the spatially-defined problem of disparity estimation into the spatial-temporal domain. Motion is analyzed in the origi...

Modelling the Stereovision-Correspondence-Analysis task by Lateral Inhibition in Accumulative Computation problem-solving method

Recently, the Algorithmic Lateral Inhibition (ALI) method and the Accumulative Computation (AC) method have proven to be efficient in modelling at the knowledge level for general-motion-detection tasks in video sequences. More precisely, the task of persistent motion detection has been widely expressed by means of the AC method, whereas the ALI method has been used with the objective of moving ...

A Simple and Fast Neural Network Approach to Stereovision

A neural network approach to stereovision is presented based on aliasing effects of simple disparity estimators and a fast coherencedetection scheme. Within a single network structure, a dense disparity map with an associated validation map and, additionally, the fused cyclopean view of the scene are available. The network operations are based on simple, biological plausible circuitry; the algo...

A Stereovision Matching Strategy for Images Captured with Fish-Eye Lenses in Forest Environments

We present a novel strategy for computing disparity maps from hemispherical stereo images obtained with fish-eye lenses in forest environments. At a first segmentation stage, the method identifies textures of interest to be either matched or discarded. This is achieved by applying a pattern recognition strategy based on the combination of two classifiers: Fuzzy Clustering and Bayesian. At a sec...
