Human action recognition is currently a hot topic research domain including a variety of applications such as human HMI, rehabilitation and surveillance. The majority of existing approaches are based on the skeleton. They utilize either the joint locations or the joint angles in order to present a human skeleton. This study introduce a novel framework, which allows compact representation, quick comparison...
The revolution of technologies (social networks, smartphones, GPS and Remote Sensing Image) increase the volume of informations wich makes humanity in new need “Storage of huge volume of data”. the traditional strategy to store data become problem for humanity and then this need build new art to resolve this problems the “Spatial Big Data (SBD)” SBD store proncipally three types of data:vector data,...
The recent advances of hyperspectral remote sensing systems lead to a vastly improved ability to classify land-cover classes that are very similar in their spectral properties. In addition, Hyperspectral Imaging has cleared the path for a wide range of applications in the field of geology for the regional mapping of rock types and mineral prospecting. The erosion process that begins with changes in...
Hyperspectral image has a great ability to discriminate the ground object by providing a fine spectral resolution image. This progress in hyperspectral technologies causes some problems including mixed pixel problem, which is a main issue for hyperspectral image classification and target detection because more than one class can be detected in a single pixel. In order to identify mixed pixel composition...
Hyperspectral sensors (HS) are next-generation optical sensors that have excellent spectroscopic performance with hundreds of spectral bands. Multispectral sensors (MS) are conventional optical sensors that have a few tens of spectral bands with high spatial resolution. This work aims to combine, the spectral information of the hyperspectral image with the spatial and spectral information of the multispectral...
