A Simple and Efficient Image Stabilization Method for Coastal Monitoring Video Systems
remote sensing Article A Simple and Efficient Image Stabilization Method for Coastal Monitoring Video Systems Isaac Rodriguez-Padilla 1,* , Bruno Castelle 1 , Vincent Marieu 1 and Denis Morichon 2 1 CNRS, UMR 5805 EPOC, Université de Bordeaux, 33615 Pessac, France; [email protected] (B.C.); [email protected] (V.M.) 2 SIAME-E2S, Université de Pau et des Pays de l’Adour, 64600 Anglet, France; [email protected] * Correspondence: [email protected] Received: 21 November 2019; Accepted: 21 December 2019; Published: 24 December 2019 Abstract: Fixed video camera systems are consistently prone to importune motions over time due to either thermal effects or mechanical factors. Even subtle displacements are mostly overlooked or ignored, although they can lead to large geo-rectification errors. This paper describes a simple and efficient method to stabilize an either continuous or sub-sampled image sequence based on feature matching and sub-pixel cross-correlation techniques. The method requires the presence and identification of different land-sub-image regions containing static recognizable features, such as corners or salient points, referred to as keypoints. A Canny edge detector (CED) is used to locate and extract the boundaries of the features. Keypoints are matched against themselves after computing their two-dimensional displacement with respect to a reference frame. Pairs of keypoints are subsequently used as control points to fit a geometric transformation in order to align the whole frame with the reference image. The stabilization method is applied to five years of daily images collected from a three-camera permanent video system located at Anglet Beach in southwestern France. -

Thorpe is National Marketing Executive for Broadcast & Communications, Canon USA Inc. He joined Canon U.S.A.’s Broadcast and Communications division in 2004, working with with networks, broadcasters, mobile production companies, program producers, ad agencies, and filmmakers. Before Canon, Larry spent more than 20 years at Sony Electronic, begining 1982. He worked for RCA’s Broadcast Division from 1966 to 1982, where he developed a range of color television cameras and telecine products. In 1981, Thorpe won the David Sarnoff Award for his innovation in developing the first automatic color studio camera. From 1961 to 1966, Thorpe worked in the Designs Dept. of the BBC in London, England, where he participated in the development of a range of color television studio products. Larry has written more than 70 technical articles. He is a lively and wonderfully articulate speaker, in great demand at major industry events. This article began as a fascinating lecture at NAB 2010. Photo by Mark Forman. Introduction Lens and camera shake is a significant cause of blurred images. These disturbances can come as jolts when a camera is handheld or shoulder mounted, from vibrations when tripod-mounted on an unstable platform or in windblown environments, or as higher vibration frequencies when operating from vehicles, boats, and aircraft. A variety of technologies have been applied in the quest for real-time compensation of image unsteadiness. 1. Mechanical: where the lens-camera system is mounted within a gyro-stabilized housing. -

A Map of the Canon EOS 6D
CHAPTER 1 A Map of the Canon EOS 6D f you’ve used the Canon EOS 6D, you know it delivers high-resolution images and Iprovides snappy performance. Equally important, the camera offers a full comple- ment of automated, semiautomatic, and manual creative controls. You also probably know that the 6D is the smallest and lightest full-frame dSLR available (at this writing), yet it still provides ample stability in your hands when you’re shooting. Controls on the back of the camera are streamlined, clearly labeled, and within easy reach during shooting. The exterior belies the power under the hood: the 6D includes Canon’s robust autofocus and metering systems and the very fast DIGIC 5+ image processor. There’s a lot that is new on the 6D, but its intuitive design makes it easy for both nov- ice and experienced Canon shooters to jump right in. This chapter provides a roadmap to using the camera controls and the camera menus. COPYRIGHTED MATERIAL This chapter is designed to take you under the hood and help fi nd your way around the Canon EOS 6D quickly and easily.

Clinical Photography Manual by Kris Chmielewski Introduction
Clinical Photography Manual by Kris Chmielewski Introduction Dental photography requires basic knowledge about general photographic rules, but also proper equipment and a digital workflow are important. In this manual you will find practical information about recommended equipment, settings, and accessories. For success with clinical photo documentation, consistency is the key. The shots and views presented here are intended as recommendations. While documenting cases, it is very important to compose the images in a consistent manner, so that the results or stages of the treatment can easily be compared. Don’t stop documenting if a failure occurs. It’s even more important to document such cases because of their high educational value. Dr. Kris Chmielewski, DDS, MSc Educational Director of Dental Photo Master About the author Kris Chmielewski is a dentist and professional photographer. Highly experienced in implantology and esthetic dentistry, he has more than 20 years experience with dental photography. He is also a freelance photographer and filmmaker, involved with projects for the Discovery Channel. 2 CONTENT Equipment 4 Camera 5 Initial camera settings for dental photography 7 Lens 8 Flash 10 Brackets 14 Accessories Retractors 15 Mirrors 16 Contrasters 17 Camera & instrument positioning 18 Intraoral photography Recommended settings 22 Frontal views 23 Occlusal views 23 Lateral views 24 Portraits Recommended settings 26 Views 27 Post-production 29 How to prepare pictures for lectures and for print 30 3 Equipment Equipment For dental photography, you need a camera with a dedicated macro lens and flash.

Camera Support for Use of Unchipped Manual Lenses

Camera support for use of unchipped manual lenses Henry Dietz; University of Kentucky; Lexington, Kentucky Abstract As interchangeable-lens cameras evolve into tightly inte- grated electromechanical systems, it is becoming increasingly awkward to use optics that cannot electronically communicate with the camera body. Such lenses are commonly referred to as “unchipped” because they lack integrated circuitry (aka, chips) that could interface with the camera body. Despite the awkward- ness, there is a large community of photographers who prefer to use manual lenses. Not only is there an increased demand for vin- tage lenses, but the variety of newly-manufactured fully-manual lenses has been growing dramatically in recent years. Although manual lenses will never provide all the features and performance of lenses created as integrated parts of a cam- era system, the current work explores a variety of methods by which digital cameras can significantly improve the usability of Figure 1.
