this paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. the motion of four pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (dpiv) and image processing methods and optimal coefficients of the motion equations and appropria...

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...

This paper addresses the use of spatiotemporal transform methods applied to the analysis of dynamic image sequences and the characterization of image motion. Image motion including a divergent component (resulting from a looming camera component) is analyzed in the spatiotemporal Mellin Transform (MT) domain, resulting in the separation of the spectrum into two parts: a structural term correspo...

Time varying image analysis s Motion detection s Motion estimation s Egomotion and structure from motion Time-varying image analysis-2 Larry Davis The problems s Visual surveillance – stationary camera watches a workspace-find moving objects and alert an operator – moving camera navigates a workspace-find moving objects and alert an operator s Image coding – use image motion to perform more eff...

⎯ This paper is to present vision based motion analysis for human-robot interaction, which analyzes camera motion and human motion. Motion of camera is compensated by comparing edge features among consecutive image frames. Candidate regions of human motion are found by differencing between transformed t image and t-1 image. Human motion is finally decided by image features and motion analysis. ...
