Corn height measured manually has shown promising results in improving the relationship between active-optical (AO) sensor readings and crop yield. Manual measurement of corn height is not practical in US commercial corn production, so an alternative automatic method must be found in order to capture the benefit of including canopy height into in-season yield estimates and from there into in-se...

Digital images are generated by different sensors, understanding which kind of sensor has acquired a certain image could be crucial in many application scenarios where digital forensic techniques operate. In this paper a new methodology which permits to establish if a digital photo has been taken by a photo-camera or has been scanned by a scanner is presented. The specific geometrical features ...

This is an instructional document concerning the steps required to read and display the unprocessed sensor data stored in RAW photo formats. RAW photo files contain the raw sensor data from a digital camera; while it can be quite scientifically useful, raw data must generally be processed before it can be displayed. In this tutorial, the nature of the raw sensor data is explored. The scaling an...

In this paper we describe a free-space optics (FSO) based mobile sensor network that is not subject to RF interference common to wireless sensor networks. FSO-based mobile sensor networks can potentially be used in applications where security of communication, including freedom from susceptibility to jamming, is important. The design of nodes containing multiple transceivers each composed of an...

Acoustic sensors have been used for battlefield applications since World War I. Acoustic sensors provide several advantages and are increasingly employed in the modern high-tech battlefield. The twenty-first century battlefield calls for cutting-edge technology for military superiority and deployment of state-of-the-art acoustic sensor systems that employ advanced acoustic signal processing. Th...

The large digital frame camera UltraCamX was introduced in 2006 by Vexcel Imaging (a Microsoft Company). This paper will give a short technical overview about the concept of the camera and more information on the radiometric quality of the UltraCamX. The focus in this paper is set on the radiometric quality of the sensors. Already recorded image data are analyzed in detail for their radiometric...

Underwater acoustic network is one of the rapidly growing areas of research and finds different applications for monitoring and collecting various data for environmental studies. The communication among dynamic nodes and high error probability in an acoustic medium forced to maximize energy consumption in Underwater Sensor Networks (USN) than in traditional sensor networks. Developing energy-ef...
