Design of a new biometric system based on hand geometry images using deep learning methods

Dorsal hand vein patterns are unique to each individual, making them a promising tool for accurate identity recognition. This thesis focuses on biometric analysis of human identification. The tecnocampus hand image dataset is used to validate feature extraction methods on dorsal hand images. The study compares and analyzes three Convolutional Neural Network CNN architectures: ResNet-50, GoogleNet, and SqueezeNet, which offer distinct approaches to feature extraction. It evaluates the performance of each method by applying them to a dataset. Based on the analysis, the most effective features are selected from the respective architectures. By leveraging the robustness of assessed CNN architectures and harnessing the power of Euclidean distance, the proposed approach achieves remarkable outcomes in the realm of image recognition. It uses feature vectors to measure similarity between dorsal images, and uses Euclidean distance to measure the similarity between feature vectors. This allows the algorithm to accurately identify and match hand vein patterns with high accuracy. With an overall accuracy of 97.32%, this research has significant implications for the field of biometric identification and could serve as a valuable foundation for future advancements in this area.
