Seasonal Vegetation Change Detection Using Independent Component Analysis
The seasonal analysis of vegetation can be considered as looking for fundamental redundant information and detecting, at the same time, the natural changes of the vegetative cover undergone by the observed scene. From the statistical point of view, the redundant information can be quantified by the correlation coefficients between the multi-temporal images while the natural changes can be consi...
متن کاملInvestigation on the Patterns of Global Vegetation Change Using a Satellite-Sensed Vegetation Index
The pattern of vegetation change in response to global change still remains a controversial issue. A Normalized Difference Vegetation Index (NDVI) dataset compiled by the Global Inventory Modeling and Mapping Studies (GIMMS) was used for analysis. For the period 1982–2006, GIMMS-NDVI analysis indicated that monthly NDVI changes show homogenous trends in middle and high latitude areas in the nor...
متن کاملA palynological investigation of Holocene vegetation change in Torres Strait, seasonal tropics of northern Australia
The islands of Torres Strait occupy a shallow area of submerged continental shelf narrowly separating Cape York Peninsula, Australia, from New Guinea. The human history of Torres Strait is unique with respect to mainland northern Australia. Island vegetation, however, exhibits a strong affinity with the environments of the western lowlands regions of Cape York Peninsula and with the vegetation ...
متن کاملInvestigating the applicability of conventional vegetation indices for vegetation change detection in different environmental conditions
Vegetation indices have been developed to characterize and extract the Earth's vegetation cover from space using satellite images. For detection of vegetation changes, usually temporal images are independently analyzed or vegetation index differencing is implemented. A review on previous studies reveal that, in spite of developing several vegetation indices, to extract vegetation cover or veget...
