With the increased spatial resolution of current sensor constellations, more details are captured about our changing planet, enabling the recognition of a greater range of land use/land cover classes. While pixel- and object-based classification approaches are widely used for extracting information from imagery, recent studies have shown the importance of spatial contexts for discriminating more specific...
Nowadays, Content Based Image retrieval (CBIR) has been one of the most interesting research areas among researchers of technology-giants and academic institutions. Various CBIR techniques in literature show that there are three key properties in image retrieval viz. color, texture and shape. In this paper a detailed classification along with the challenges and issues of CBIR techniques evolved during...
Description of object spatial relation in image is the crucial technology in the image retrieval of content. Using spatial location relation to identify thing conforms to people's custom. This paper reviews and compares the methods that describe object spatial relation and points out existent problem and put forwards suggestion for improvement.
