The aim of the study is to validate hyperspectral ground data for the detection of buried architectural remains. For this reason spectro-radiometric measurements were taken from an archaeological area in Cyprus. Field spectroradiometric measurements were undertaken from March to May of 2010. Spectro-radiometric measurements were taken over the previously detected magnetic anomalies using the GE...

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 quality have been somehow underestimated. However, radiometric problems may cause geometric artefacts, lead to loss of film information, color shifts and noise, and influence the increasingly used subseq...

It is a well know result that the geometry of pan and tilt (perspective) cameras auto-calibrate using just the image information. However, applications based on panoramic background representations must also compensate for radiometric effects due to camera motion. In this paper we propose a methodology for calibrating the radiometric effects inherent in the operation of pan-tilt cameras, with a...

This manuscript characterizes several bands of multi-spectral images obtained with different radiometric and spatial resolution by IKONOS-2 and LANDSAT-7 satellites by multifractal analysis. Three of the studied bands were in the visible wavelength spectrum (red, green and blue), while the fourth one was in the near-infrared region. IKONOS-2 images were taken with a radiometric resolution of 11...

In this work, we describe an improved thermal-vacuum compatible flat plate radiometric source which has been developed and utilized for the characterization and calibration of remote optical sensors. This source is unique in that it can be used in situ, in both ambient and thermal-vacuum environments, allowing it to follow the sensor throughout its testing cycle. The performance of the original...

Introduction In the present nuclear age, the devastating effects of radioactivity have been highlighted by such issues as nuclear weapons testing and radioactive waste disposal, and by the reactor incidents at Three Mile Island and Chernobyl. These events illustrate the vexing problems that can be associated with high levels of radioactivity. However, the presence of radioactivity is not limite...

This manuscript first revises the performance of total power, Dicke-type and noise-injection microwave radiometers. Equations for the radiometric resolution are revised or derived, and their performance in terms of the radiometric resolution improvement with respect to the ideal total power radiometer resolution is evaluated. It is then shown that the radiometric resolution of noise-injection r...

This paper covers the design and initial performance analysis of the radiometric calibration pipeline software for the EO-1 Advanced Land Imager (EO-1). The design and implementation of the software and of the radiometric calibration database are discussed. Radiometric calibration data were gathered in the laboratory during integration and test and were used for initializing the database. This ...

We describe a radiometric profiler that provides accurate temperature, humidity and cloud liquid profiles during clear and cloudy conditions. The radiometer observes radiation intensity at 12 microwave frequencies, along with infrared and surface meteorological measurements. Historical radiosonde and neural network or regression methods are used for profile retrieval. We compare radiometric, ra...

This work is on development of a method for automatic registration of satellite images acquired on different dates, for both geometric and radiometric correction with respect to a reference image. Mutual information statistics is used as the similarity metric of geometric and radiometric registration. Affine and linear transformations are used in geometric and radiometric correction respectivel...
