Acoustic seafloor sediment classification using self-organizing feature maps
(IEEE, 2001)A self-organizing feature map (SOFM), a kind of artificial neural network (ANN) architecture, is used in this work for continental shelf seafloor sediment classification. Echo data are acquired using an echosounding system ... -
Echo-waveform classification using model and model free techniques: Experimental study results from central western continental shelf of India
(Marine Technology Society, 2005)Seafloor classifications and characterization using acoustic backscatter data from the central western continental shelf of India is presented in this work. Single beam sea-floor echo data using two frequencies: 33 kHz and ... -
Miniature sonar for obstacle detection on samll AUV Maya
(Allied, 2007)Autonomous platforms are increasingly able to collect in-situ data with least disturbance to the parameters under measurements. To attain high level of autonomy they need to posses capabilities to detect and avoid obstacles ... -
Preference of echo features for classification of seafloor sediments using neural networks
(Springer, 2010)Selection of a set of dominant echo features to classify seafloor sediments using a multilayer perceptron neural network is investigated at two acoustic frequencies (33 and 210 kHz). Several sets of inputs with different ... -
Seafloor classification using acoustic backscatter echo-waveform - Artificial neural network applications
(IEEE Singapore Section Secretariat, 2006)In this paper seafloor classifications system based on artificial neural network (ANN) has been designed. The ANN architecture employed here is a combination of Self Organizing Feature Map (SOFM) and Linear Vector Quantization ... -
VM-ADCP measured upper ocean currents in the southeastern Arabian Sea and Equatorial Indian Ocean during December, 2000
(PORSEC 2002 Secretariat; Bogor; Indonesia, 2002)The Vessel-Mounted Acoustic Doppler Current Profiler (VM-ADCP) measured currents in the upper 200 m along the cruise track covering the southeastern Arabian Sea and the Eastern Equatorial Indian Ocean during northern winter ...
