Existing image segmentation algorithms have recently been ported to the widely used ERDAS Imagine graphical user interface. Within the USDA Forest Service Region 5 Remote Sensing Lab these algorithms have traditionally been applied to Landsat TM data for the purpose of landscape delineation. A less confining image processing environment, combined with the wide availability of finer resolution d...

Satellites used for remote sensing are, in general, capable of acquiring two different types of images: multispectral (MS) images and a panchromatic (Pan) image. The MS sensors provide multiband images with accurate spectral (color) information but with low spatial resolution. In this project, we propose an edge preserving multiresolution fusion by using subsampled as well as nonsubsampled CT. ...

This article presents the scientific outcomes of 2022 Hyperspectral Pansharpening Challenge organized by 12th IEEE Workshop on Image and Signal Processing: Evolution in Remote Sensing (IEEE WHISPERS 2022). The aims at fusing a panchromatic image with hyperspectral data to get high spatial resolution cube same while preserving spectral information data. Four datasets acquired PRISMA mission owne...

In the recent years, the development of digital aerial sensors signifies a revolutionary change in aerial image acquisition, and the possibility of fully digital processing from image acquisition to the generation of value-added products for various applications. LH Systems developed the ADS40, a pushbroom sensor system, which offers on a single camera system the possibility to acquire 3 panchr...

The main aim of the research described in the paper was analyse the accuracy of photointerpretation of impervious surface using IKONOS images and its influence on the imperviousness factor determination. Two kinds of IKONOS image were chosen to tests: panchromatic and colour pansharp. Airborne ortopho (pixel size of 0.2m) was applied as a reference. Six operators, digitised three times, two kin...

Most bamboo forests grow in humid climates in low-latitude tropical or subtropical monsoon areas, and they are generally located in hilly areas. Bamboo trunks are very straight and smooth, which means that bamboo forests have low structural diversity. These features are beneficial to synthetic aperture radar (SAR) microwave penetration and they provide special information in SAR imagery. Howeve...

Triggered by the spread of digital aerial image acquisition, the quantification and improvement of spatial image resolution has become a topic of considerable interest for photogrammetric processing. Within our paper, the determination of image resolution based on the Rayleigh criterion and the point spread function will be discussed. These techniques then can be applied in order to exactly eva...
