The document discusses the detection and extraction of features of sea mines using CNN architecture. It first provides background on deep neural networks, convolutional neural networks, and generative adversarial networks. It then summarizes previous literature on related topics like sonar target recognition, underwater image classification, pretext-invariant representation learning, and underwater mine detection using Mask RCNN. The paper proposes detecting sea mines in real-time using a more extensive dataset to train models like YOLO v3 for improved performance across variations in mines. It concludes by listing references used in the document.
