Ship recognition method combined with image segmentation and deep learning feature extraction in video surveillance

To solve the problem of ship recognition in video images, a ship recognition method based on Morphological Watershed image segmentation and Zemike moment is proposed. Firstly, the video frame image is pre-processed by gray algorithm, and then the gray image is filtered by wavelet transform to remove noise. After denoising, the Morphological Watershed algorithm is used to segment the image and extract the ship area in the image. Next, the feature of ship image is extracted based on deep learning convolution neural network (CNN) and Zemike moment method. Finally, the KNN-SVM classifier is trained according to the image features and class labels to realize the automatic recognition of ships. Experimental results show that the method can effectively identify 3 types of ships, with an average detection accuracy of 87%.
