Enhancing Underwater Image Segmentation with Deep Learning: A Novel Approach to Dataset Expansion and Preprocessing Techniques

Underwater image processing combined with machine learning offers significant potential for enhancing the capabilities of underwater robots across various marine exploration tasks. Image segmentation, a key aspect of machine vision, is crucial for identifying and isolating objects of interest inside underwater images. Traditional segmentation methods, similar to threshold-based and morphology-based algorithms, have been employed but need assistance accurately delineating objects within the complex underwater environment where image degradation is common.

Researchers increasingly use deep learning techniques for underwater image segmentation to deal with these challenges. Deep learning methods, including semantic and instance segmentation, provide more precise evaluation by enabling pixel-level and object-level segmentation. Recent advancements, similar to FCN-DenseNet and Mask R-CNN, promise to enhance segmentation accuracy and speed. Nevertheless, further research is required to beat challenges like limited dataset availability and image quality degradation, ensuring robust performance in underwater exploration scenarios.

To take care of the challenges posed by limited underwater image datasets and image quality degradation, a research team from China recently published a brand new paper proposing progressive solutions.

The proposed method relies on the next steps: Firstly, they expanded the scale of the underwater image dataset by employing techniques similar to image rotation, flipping, and a Generative Adversarial Network (GAN) to generate additional images. Secondly, they applied an underwater image enhancement algorithm to preprocess the dataset, addressing issues related to image quality degradation. Thirdly, the researchers reconstructed the deep learning network by removing the last layer of the feature map with the most important receptive field within the Feature Pyramid Network (FPN) and replacing the unique backbone network with a light-weight feature extraction network.

Using image transformations and a ConSinGan network, they enhanced the initial images from the Underwater Robot Picking Contest (URPC2020) to create an underwater image dataset, as an illustration, segmentation. This network uses three convolutional layers to expand the dataset by producing higher-resolution images after several training cycles. Additionally they labeled goal positions and categories using a Mask R-CNN network for image annotation, constructing a completely labeled dataset in Visual Object Classes (VOC) format. Creating latest datasets increases their diversity and unpredictability, which is very important for developing strong segmentation models that may adapt to numerous undersea conditions.

The experimental study assessed the effectiveness of the proposed approach in enhancing underwater image quality and refining instance segmentation accuracy. Quantitative metrics, including information entropy, root mean square contrast, average gradient, and underwater color image quality evaluation, were utilized to judge image enhancement algorithms, where the mix algorithm, notably WAC, exhibited superior performance. Validation experiments confirmed the efficacy of knowledge augmentation techniques in refining segmentation accuracy and underscored the effectiveness of image preprocessing algorithms, with WAC surpassing alternative methods. Modifications to the Mask R-CNN network, particularly the Feature Pyramid Network (FPN), improved segmentation accuracy and processing speed. Integrating image preprocessing with network enhancements further bolstered recognition and segmentation accuracy, validating the approach’s efficacy in underwater image evaluation and segmentation tasks.

In summary, integrating underwater image processing with machine learning holds promise for enhancing underwater robot capabilities in marine exploration. Deep learning techniques, including semantic and instance segmentation, offer precise evaluation despite the challenges of the underwater environment. Recent advancements like FCN-DenseNet and Mask R-CNN show potential for improving segmentation accuracy. A recent study proposed a comprehensive approach involving dataset expansion, image enhancement algorithms, and network modifications, demonstrating effectiveness in enhancing image quality and refining segmentation accuracy. This approach has significant implications for underwater image evaluation and segmentation tasks.
