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...
Fixed pattern noise (FPN) or nonuniformity caused by device and interconnect parameter variations across an image sensor is a major source of image quality degradation especially in CMOS image sensors...
Gradient-based optical flow estimation methods such as Lucas Kanade method work well for scenes with small dlsplacements but fail when objects move with large displacements. Hierarchical matching-base...
People find their way through cluttered environments with ease and without injury. How do they do it? Two approaches to wayfmding are considered: Differential motion parallax (DMP) is a retinal motion...
Computer-generated sequences simulated observer movement toward 10 randomly placed poles, 1moving and 9 stationary. When observers judged their direction of movement, or heading, they used 3 related i...
Recent advances in imaging sensor technology make high frame rate video capture practical. As demonstrated in previous work, this capability can be used to enhance the performance of many image and vi...
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...
This paper presents the Contrast Invariant and Affine Optical Flow(CIAO), a dense area-based sub-pixel image matching algorithm.CIAO does not force the estimated disparity field between two images to ...
In OFS, users employ an off-band signaling protocol to request lightpaths for their large unscheduled bursty transactions, and the network dynamically schedules a dedicated, end-to-end lightpath for t...
