Zero Phase Representation of Panorami

New adaptive interpolation schemes for efficient meshbased motion estimation

Motion estimation and compensation is an essential part of existing video coding systems. The mesh-based motion estimation (MME) produces smoother motion field, better subjective quality (free from blocking artifacts), and higher peak signal-to-noise ratio (PSNR) in many cases, especially at low bitrate video communications, compared to the conventional block matching algorithm (BMA). Howev...

Parallelized Block Match Algorithm on Multi-core Processors

In order to increase the coding efficiency of H.264/AVC, this paper proposed a parallelized approach of full search (FS) algorithm for motion estimation on Graphic Processor Unit (GPU) using computing unified device architecture (CUDA). By utilizing the independence among different MBs, we are able to take the full advantage of the computational power of CUDA and speed up the FS motion estimati...

تحلیل 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...

Loading Estimation of Flapping Wings under Aeroelastic Effect Using Finite Element Method

The aim of this paper is to provide an aeroelastic computational tool which determines the induced wing loads during flapping flight. For this purpose, a Finite Element (FE) code based on a four-node plate bending element formulation is developed to simulate the aeroelastic behavior of flapping wings in low incompressible flow. A quasi-steady aerodynamic model is incorporated into the aeroelast...
