This paper presents an image fusion method suitable for pan-sharpening of multispectral (MS) bands, based on nonseparable multiresolution analysis (MRA). The low-resolution MS bands are resampled to the fine scale of the panchromatic (Pan) image and sharpened by injecting highpass directional details extracted from the high-resolution Pan image by means of the curvelet transform (CT). CT is a n...

This paper presents a novel approach to automatic classifying and identifying of tree leaves using image segmentation fusion. With the development of mobile devices and remote access, automatic plant identification in images taken in natural scenes has received much attention. Image segmentation plays a key role in most plant identification methods, especially in complex background images. Wher...

Digital orthoimages are becoming increasingly of interest as they provide up-to-date information for a wide range of applications. Facing the need for accurate spatial information this paper aims to the production of orthoimages and their further processing, as well as to the three dimensional visualization of the resulting images. The data used are one panchromatic image from Spot-3, with spat...

The modern remote sensing imaging sensors, like those in the IKONOS and QuickBird satellites, are capable of generating panchromatic images with about one meter spatial resolution. The principal objective of fusion in remote sensing is to obtain images that can combine the spectral characteristic of the lowresolution multispectral images with the spatial information of the high-resolution panch...

The aim of this study was to evaluate the impact of image fusion techniques on vegetation classification accuracies in a complex wetland system. Fusion of panchromatic (PAN) and multispectral (MS) Quickbird satellite imagery was undertaken using four image fusion techniques: Brovey, hue-saturation-value (HSV), principal components (PC), and Gram– Schmidt (GS) spectral sharpening. These four fus...

objective(s): in this study, we aimed to analyze the relationship between the diagnostic ability of fused single photon emission computed tomography/computed tomography (spect/ct) images in localization of parathyroid lesions and the size of adenomas or hyperplastic glands. methods: five patients with primary hyperparathyroidism (phpt) and 4 patients with secondary hyperparathyroidism (shpt) we...

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...
