Abstract: Image data enhancement is a vital method in the field of deep learning for enhancing model performance and generalization capabilities.This thesis explores various image data augmentation methods and their effectiveness in improving the performance of deep learning neural networks.The study begins with an overview of image data augmentation techniques, including rotation, flipping, scaling, cropping, translation, brightness adjustment, contrast adjustment, and Gaussian noise addition.Each augmentation method is examined in detail, discussing its impact on the variety and richness of the training collection.Following the theoretical overview, a series of experiments are conducted using widely used deep learning models such as Convolutional Neural Networks (CNNs), VGG, and MobileNet.These experiments aim to evaluate the performance of different augmentation methods in terms of model accuracy, robustness, and generalization on benchmark datasets.The results of the experiments demonstrate the effectiveness of certain augmentation techniques in improving model performance, while also highlighting potential trade-offs and considerations for real-world applications.Additionally, the study investigates the impact of augmentation parameters such as magnitude, probability, and combination strategies on model training dynamics and convergence.This thesis provides valuable insights into the role of image data augmentation in deep learning and offers practical guidance for selecting and implementing augmentation methods to enhance the effectiveness of neural networks across various computer vision assignments.
