In this work, we assessed the feasibility of using optical flow to obtain the motion estimation of a glacier. In general, former investigations used to detect glacier changes involve solutions that re...
Dense matching plays an important role in many fields, such as DEM (digital evaluation model) producing, robot navigation and 3D environment reconstruction. Traditional approaches may meet the demand ...
The aim of this study is calculation of sea surface currents (SSCs) which are estimated from satellite data sets and processed with the variance component estimation (VCE) algorithm to check role of e...
In order to perform object modelling by image processing procedures, line or feature extraction and stereo matching used to perform. However, there are some issues for efficient 3D modelling of objec...
Human emotion identification from image sequences is highly demanded nowadays. The range of possible applications can vary from an automatic smile shutter function of consumer grade digital cameras ...
The most readily available motion parameter from sequential image is optical flow. Among various optical flow estimation techniques, gradient-based approach is a common technique. This approach is bas...
In order to acquire 3D spatial data for objects using stereo image, stereo matching such as SSDA, area based matching and so on have been proposed. However, there are some issues for efficient 3D obje...
This paper is about performance evaluation of two optical flow (OF) methods for extracting sea surface curved motions like eddies. By incorporating a simple matrix and its rotation in programming proc...
In Digital Surface Model generation applications, obtaining stereo correspondences is a crucial step. The geometry of stereo image generation causes significant disparities between match points. Unlik...
