Automatic Rectification of Side-scan Sonar Images
The authors present a novel procedure for the automated rectification of side-scan sonar images. The traditional assumption of a flat seabed for the computation of the ground projection from the slant-range sonar data can later result in difficult geo-referencing and registration problems. Accurate rectification using actual seabed topography is required for precise integration of side-scan ima...
متن کاملQuantification of Walleye Spawning Substrate in a Northern Minnesota River using Side-Scan Sonar
Evaluating aquatic habitats is an important component of many ecological studies and natural resource assessments, but traditional habitat evaluations are time and labor intensive and do not provide continuous data. Side-scan sonar (SSS) can provide a low-cost method that collects continuous aquatic habitat data. We used SSS mapping to quantify suitable spawning substrate available toWalleye Sa...
متن کاملSide-scan Sonar for Inspecting Coastal Structures
INTRODUCTION: SSS has been used to map the sea bottom and search for submerged objects since the 1960's (Fleming, 1976). Recent experiments by CERC and the Buffalo District have shown SSS to be useful for inspecting both sloping coastal structures (i.e., rubble-mound jetties and breakwaters) and vertical-wall structures (i.e., concrete caissons and timber cribs). SSS is an adaptation of high-fr...

این تحقیق به منظور بررسی رابطه بین میزان استراتژیهای خود-تنظیم شده یادگیری و تمایل به ایجاد ارتباط دانشجویان زبان انگلیسی انجام شده است.علاوه بر این،روابط و کنش های موجود بین ریزسنجه های استراتژیهای خود-تنظیم شده یادگُیری ، مهارت نگارش و تمایل به برقراری ارتباط و همچنین تاٍثیرجنسیت دانشجویان زبان انگلیسی در استراتژیهای خود-تنظیم شده یادگیری و تمایل به برقراری ارتباط آنها مورد بررسی قرار گرفته شد.
15 صفحه اولHeight Estimation of a Sonar Towfish from Side-Scan Imagery
The algorithm described uses a combination of Haar wavelet decomposition and Kalman filtering to track the noisy echoes. This was able to compute the towfish height on the fly with a minimal delay and without thresholding. Its performance is demonstrated using real side-scan sonar data and is shown to be robust with respect to the great variation in echo level (including drop-outs) and to the p...
