Abstract In this paper, a stand density extraction method is proposed based on QuickBird high-resolution satellite image data of Baisha artificial forest farm in Minhou, Fujian. Firstly, through the analysis band canopy panchromatic, it known that there maximum reflectivity point canopy. Then, vegetation-covered area was extracted by normalized difference vegetation index ( NDVI ). The decision...

In this paper, a novel unsupervised approach based on PulseCoupled Neural Networks (PCNNs) for image change detection is discussed. PCNNs are based on the implementation of the mechanisms underlying the visual cortex of small mammals and with respect to more traditional neural networks architectures own interesting advantages. In particular, they are unsupervised and context sensitive. The perf...

In this work we investigated the effects to man made structures and buildings caused by the December 26th, 2003, Bam(Iran) earthquake. The epicentre of the seism was nearby the ancient urban area of Bam and caused strong damage. Thedataset was composed by preand post-earthquake QuickBird panchromatic images, with 60 cm geometric resolution.The very high resolution images acquired by...

Measurements of forest structure are important for wildlife habitat management. An optimal strategy for mapping forest structure would include detailed measurements of the vertical dimension, which are traditionally provided by field sampling, together with the broad spatial coverage afforded by remote sensing. While no single sensor is capable of delivering this at the present time, it should ...

The Hatu area, West Junggar, Xinjiang, China, is situated at a potential gold-copper mineralization zone in association with quartz veins and small granitic intrusions. In order to identify the alteration zones and mineralization occurrences in this area, the Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper (ETM+), Quickbird, Hyperion data and laboratory measured spectra were combined ...

This article presents techniques for noise filtering of remotely sensed images based on Multi-resolution Analysis (MRA). Multiresolution techniques provide a coarse-to-fine and scale-invariant decomposition of images for image interpretation. The multiresolution image analysis methods have the ability to analyze the image in an adaptive manner, capturing local information as well as global info...

The aim of this project is to evaluate the possibilities that the high resolution satellite image offers in the field of archaeological research. More specific, the present study concerns the identification of buried archaeological remains with the aid of the Pansharpened (fused) image Quickbird-2. For this purpose, the fused image (spatial resolution 0.70m and spectral resolution 4 bands), tha...
