A Modulation Transfer Function (MTF)-based fuzzy comprehensive evaluation method was proposed in this paper for the purpose of evaluating high-resolution satellite image quality. To establish the fact...
The image quality of the surveying camera will affect the stereoscopic positioning accuracy of the remote sensing satellite. The key factors closely related to the image quality are Modulation Transfe...
This paper briefly describes the post-processing influence assessment experiment, the experiment includes three steps: the physical simulation, image processing, and image quality assessment. The phys...
More and more high-spatial resolution satellite images are produced with the improvement of satellite technology. However, the quality of images is not always satisfactory for application. Due to the ...
Pleiades 1A and 1B are twin optical satellites of Optical and Radar Federated Earth Observation (ORFEO) program jointly running by France and Italy. They are the first satellites of Europe with sub-me...
The Tian-Hui 1 (TH-1) is the first stereo mapping transmission satellite in China, and the primary mission goal of the satellite is for topographic mapping at 1:50,000 scale without Ground Control Poi...
Strips can be seen in raw remote sensing images of CCD camera. The object of relative radiometric calibration is to eliminate them. This paper discusses the influence on image quality under different ...
“Beijing 1” is one Micro-satellite of the international Disaster Monitoring Constellation (DMC). It was launched successfully in 2005, and has high-powered characteristic, such as high gaining data ab...
In-flight Image Quality calibration and performance assessment activities depend on specific acquisitions and, for some of them, on dedicated guidance of the satellite platform. The operational constr...
Over the past years a noticeable increase of interest in using Unmanned Aerial Vehicles (UAV) for acquiring low altitude images has been observed. This method creates new possibilities of using geodat...
Professionals of various backgrounds have recognized the value that the use of geospatial imagery can add to their analysis. They take advantage of the widespread availability of data in vast image ...
Users of GIS are offered an abundance of aerial and satellite imagery in distributed spatial databases. Available datasets can cover the same area, differing only in quality attributes, such as resol...
In this paper, a new image processing model based on Retinex technique and multi-resolution wavelet analysis together to simulate the imaging course and focus mechanism of HSV is proposed. At first, ...
This paper describes a method for blind estimation of sharpness and resolving power from a single image. These measures can be used to characterize images in the context of the performance of image a...
Photogrammetric scanners are used more and more for the digitization of aerial images. Geometric accuracy has always played an important role in photogrammetry, while aspects of the radiometric qualit...
