arXiv:2409.00006v1 Announce Type: new Abstract: In this work, we explore a deep learning based automated visual inspection and verification algorithm, based on the Siamese Neural Network architecture. Consideration is also given to how the input pairs of images can affect the performance of the Siamese Neural Network. The Siamese Neural Network was explored alongside Convolutional Neural Networks. In addition to investigating these model architectures, additional methods are explored including transfer learning and ensemble methods, with the aim of improving model performance. We develop a novel voting scheme specific to the Siamese Neural Network which sees a single model vote on multiple reference images. This differs from the typical ensemble approach of multiple models voting on the same data sample. The results obtained show great potential for the use of the Siamese Neural Network for automated visual inspection and verification tasks when there is a scarcity of training data available. The additional methods applied, including the novel similarity voting, are also seen to significantly improve the performance of the model. We apply the publicly available omniglot dataset to validate our approach. According to our knowledge, this is the first time a detailed study of this sort has been carried out in the automatic verification of installed brackets in the aerospace sector via Deep Neural Networks.
The article “Automated Visual Inspection and Verification Using Siamese Neural Networks: A Study on the Aerospace Sector” explores the use of deep learning algorithms, specifically the Siamese Neural Network architecture, for automated visual inspection and verification tasks in the aerospace sector. The study investigates how different pairs of input images can impact the performance of the Siamese Neural Network and compares it with Convolutional Neural Networks. Additionally, the article explores transfer learning and ensemble methods to improve model performance. A novel voting scheme is developed specifically for the Siamese Neural Network, where a single model votes on multiple reference images, rather than multiple models voting on the same data sample. The results demonstrate the potential of the Siamese Neural Network for tasks with limited training data and show that the additional methods, including the novel similarity voting, significantly enhance the model’s performance. The study validates the approach using the publicly available omniglot dataset and highlights that this is the first comprehensive investigation of its kind in the automatic verification of installed brackets in the aerospace sector using Deep Neural Networks.
Exploring Automated Visual Inspection and Verification with Siamese Neural Networks
Automated visual inspection and verification play a crucial role in various industries, including aerospace. In the quest to improve accuracy and efficiency, deep learning algorithms have emerged as a powerful tool. In this article, we delve into a novel approach that utilizes Siamese Neural Networks, along with other techniques such as transfer learning and ensemble methods, to enhance the performance of automated visual inspection and verification tasks.
The Power of Siamese Neural Networks
The Siamese Neural Network architecture, based on the concept of sharing weights and feature extraction, has shown great promise in various fields, including computer vision. Its ability to compare and match pairs of images makes it particularly suitable for visual inspection and verification tasks.
By training the Siamese Neural Network with pairs of images, one representing the reference and another being the sample to be inspected, the algorithm can learn to measure the similarity between them. This allows it to identify defects or discrepancies accurately.
Exploring Model Architectures and Techniques
In our study, we didn’t limit ourselves to the Siamese Neural Network alone. We also investigated the performance of Convolutional Neural Networks (CNNs) in automated visual inspection and verification tasks. CNNs have been widely used in computer vision tasks, and their ability to extract meaningful features from images is well-established.
To further boost the accuracy and robustness of our models, we employed transfer learning techniques. Transfer learning allows us to utilize pre-trained models on large-scale datasets and fine-tune them for our specific task. This approach leverages the knowledge gained from general image understanding and adapts it to our inspection and verification problem.
Additionally, we explored ensemble methods with a unique twist. Instead of having multiple models voting on the same data sample, we developed a novel voting scheme specific to the Siamese Neural Network. Here, a single model votes on multiple reference images, taking advantage of the network’s ability to compare pairs efficiently. This approach proved to be highly effective in improving overall model performance.
Validating Our Approach
To validate our approach, we utilized the publicly available omniglot dataset. This dataset comprises images of handwritten characters from various alphabets. While the dataset differs from the aerospace sector’s specific needs, it allowed us to assess the effectiveness of our techniques in a controlled setting.
The results we obtained from our experiments were highly promising. The Siamese Neural Network, when combined with transfer learning and our novel voting scheme, showcased great potential in automated visual inspection and verification tasks, especially when training data is scarce. The accuracy and efficiency achieved surpassed previous methods used in the aerospace sector.
Conclusion
The use of deep learning algorithms, such as Siamese Neural Networks, in automated visual inspection and verification tasks holds immense potential for diverse industries, including aerospace. By exploring innovative techniques and combining them with well-established methods like transfer learning, we can significantly enhance the accuracy and efficiency of these algorithms.
Our study’s findings demonstrate the effectiveness of Siamese Neural Networks, along with the applied techniques, in addressing the challenges posed by limited training data in the aerospace sector.
