The cameracentered motion representation is ([1][5][6]): This paper presents two algorithms for estimating motion and structure from long monocular image sequences: one using interframe correspondences, the other using point trajectories. Object-centered motion represenfations and motion models &scribed by up to the second order polynomials are used to estimate motion parameters from long image...

Motion-based segmentation of image sequences is an important problem of image analysis, with numerous applications to image coding and image manipulation. We present a novel algorithm for segmenting image sequences into distinct motion trajectories. This algorithm is expressed as a system of level set partial differential equations which is solved using level set discretization schemes. We prov...

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...

In this paper we address the problem of motion estimation failure in degraded image sequences. This failure is caused by some complex events that take place in the image. As a result, the sequence of operations that rely on the motion estimation process, such as motion compensation and motion picture restoration, will fail as well. We present a statistical analysis of these complex event areas,...
