Dataset Name: Sonar Common Target Detection Dataset (SCTD) 1.0 Format: Pascal VOC with xml annotations. (voc2coco.py is also available) Authors:Dr. Peng Zhang,Dr. Mingqiang Ning, Zhisheng Zhang, Han Li, Yan Zhou, Prof. Yue Fan, Prof. Dandan Liu ...
Target signal acquisition and detection based on sonar images is a challenging task due to the complex underwater environment. In order to solve the problem that some semantic information in sonar images is lost and model detection performance is degraded due to the complex imaging environment, we...

Compared to Nao-Chatbot, the participants reported significantly higher scores for Nao-SONAR also in terms of feeling more comfortable with and better understood by the robot during interactions, and in terms of their perception of having something in common with the robot. The participants reported...
An Automatic Target Detection Algorithm for Swath Sonar Backscatter Imagery, Using Image Texture and Independent Component Analysis In the present paper, a methodological scheme, bringing together common Acoustic Seabed Classification (ASC) systems and a powerful data decomposition approach, called Independent...
Detection/Classification task of SONAR signals, especially in the passive SONAR system, is one of the most challenging areas in this field. In passive SONAR system, received noises with SNR as low as -15dB are very common at the receiver (Urick 1983). Added reverberation and scattering, ...
single-target detection by lowering a standard copper sphere of known target strength (TS) below the transducer and moving it in a raster using a winch driven setup (Fig.S2). The system uses a split-beam configuration to obtain precise information on the sphere’s position based on phase ...
[21] and is named SCTD (sonar common target detection). It included 497 images obtained by side-scan sonars, on which 514 targets are included. The sample numbers of SCTD are shown in Table 2. Table 2. Sample numbers of SCTD. Generally speaking, the dataset will be split into three ...
By pre-training the large-scale Underwater Acoustic Target Detection Dataset (UATD dataset), DA-YOLOV7 obtains initial weights, fine-tuned on the smaller Smaller Common Sonar Target Detection Dataset (SCTD dataset), thereby reducing the risk of overfitting which is commonly encountered in small ...
