Light-field imaging systems have received a lot of attention recently, especially with the release of Lytro cameras for consumer application. Extensive research has been conducted in optimizing and developing applications for light-field images [1,2]. To investigate the potential use of light-field imaging systems as an experimental analysis tool, an automated image processing algorithm was dev...
In this paper we present a new framework for detection of dynamic obstacles in tire unstructured outdoor road environment by purposively irttegmting binocular color image sequence. In our system, color image segmentation, stereo obstacle detection, visual egomotion estirnation,and moving object analysis, are all built-in task-oriented modules and hence are eficient and robust. Most of these fun...
since the birth of multi–spectral imaging techniques, there has been a tendency to consider and process this new type of data as a set of parallel gray–scale images, instead of an ensemble of an n–d realization. although, even now, some researchers make the same assumption, it is proved that using vector geometries leads to better results. in this paper, first a method is proposed to extract th...
The “fly algorithm” is a fast artificial evolution-based image processing technique. Previous work has shown how to process stereo image sequences and use the evolving population of “flies” as a continuously updated representation of the scene for obstacle avoidance in a mobile robot. In this paper, we show that it is possible to use several sensors providing independent information sources on ...
Existing shape-from-shading algorithms assume constant reflectance across the shaded surface. Multi-colored surfaces are excluded because both shading and reflectance affect the measured image intensity. Given a standard RGB color image, we describe a method of eliminating the reflectance effects in order to calculate a shading field that depends only on the relative positions of the illuminant...
In this paper, we propose an efficient stereo image rectification method using the horizontal baseline. Since the stereo camera is generally manually arranged, there are geometric errors due to the camera misalignment and the differences between the camera internal characteristics. Although the conventional calibration-based stereo image rectification method is simple, it has an opportunity to ...
www.ecsi.org/dasip Nowadays, 3D vision is a common tool that is now available in the consumer electronics and many current and future applications require high speed estimation of the object depths of acquired image scenes. High speed acquisition and image processing are challenging tasks that are the heart of this session. According to the process and acquisition requirement, the best hardware...

sensors onboard meteorological satellites such as modis and avhrr are able to collect information adequate in frequency but with low spatial resolution. the problem can be overcome, if one finds a way to increase the quality of the vegetation indices through searching in each individual pixel of the images, employing concurrent higher spatial resolution images. the objective of this study was t...
