Computation Optical Flow Using Pipeline Architecture
Accurate estimation of motion from time-varying imagery has been a popular problem in vision studies, This information can be used in segmentation, 3D motion and shape recovery, target tracking, and other problems in scene analysis and interpretation. We have presented a dynamic image model for estimating image motion from image sequences, and have shown how the solution can be obtained from a ...
متن کاملتحلیل حرکت جریانات دریائی در تصاویر حرارتی سطح آب دریا
Oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. For instance Sea Surface Temperature (SST) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. The purpose of this thesis is to derive a relatively complete frame...
متن کاملRobust Hybrid Motion Force Control Algorithm for Robot Manipulators
In this paper we present a robust hybrid motion/force controller for rigid robot manipulators. The main contribution of this paper is that the proposed hybrid control system is able to accomplish motion objectives in free directions and force objectives in constrained directions under parametric uncertainty both in robot dynamics and stiffness constraint constant. Also, the given scheme is prov...
متن کاملRobust Global Motion Estimation Using a Simplified M-Estimator Approach
Global motion estimation is an important task in a variety of video processing applications, such as coding, segmentation, classification/indexing or mosaicing. Due to the possible presence of differently moving foreground objects and other sources of distortions, robust methods such as M-estimators have to be applied. We present a simplified implementation of a robust M-estimator for global mo...
متن کاملRobust direct motion estimation considering discontinuity
In this paper, we propose a robust motion estimation algorithm using uncalibrated 3D motion model considering depth discontinuity. Most of the previous direct motion estimation algorithms with 3D motion model compute the depth value through the local smoothing, which result in erroneous results at depth discontinuity. In this paper, we overcome this problem at depth discontinuity by adding disc...
