Underwater Photogrammetry for Archaeology
Archaeological excavations are often irreversibly destructive, so it is important to accompany them with detailed documentation reflecting the accumulated knowledge of the excavation site. This documentation is usually iconographic and textual. Graphical representations of archaeological sites such as drawings, sketches, watercolors, photographs, topography, and photogrammetry are indispensable...
متن کاملLUV: The Low Cost Underwater Vehicle
In recent years underwater robotics has become a major area of research owing to the development of many diverse technologies. Autonomous underwater vehicles (AUVs) are used today for exploration, pipeline monitoring, military reconnaissance and other scientific tasks. AUVs can also be used effectively to teach principles in many disciplines of science ranging from physics to robotics. Any good...
متن کاملQuality Evaluation Method for Underwater Image Communication
A simulation based on Gilbert-Elliot packet loss model is developed to simulate an image transmitting system in underwater acoustic channel. This developed system is applied as a platform to study the relation between image quality assessment parameter PSNR, image activity measure (IAM) and channel’s packet loss rate. A group of sample images were transmitted in this communication system and a ...
متن کاملQuality-Guided Image Denoising for Low-Cost Fundus Imaging
The restoration of noisy images is an essential pre-processing step in many medical applications to ensure sufficient quality for diagnoses. In this paper we present a new quality guided approach for denoising of eye fundus images that suffer from high noise levels. The denoising is based on image sequences and an adaptive frame averaging approach. The novelty of the method is that it takes an ...
متن کاملObjectively Assessing Underwater Image Quality for the
In order to automatically enhance and restore images, especially those taken from underwater environments where scattering and absorption by the medium strongly influence the imaging results even within short distances, it is critical to have access to an objective measure of the quality of images obtained. This contribution presents an approach to measure the sharpness of an image based on the...
