Enhancing The Accuracy of Image Classification Using Deep Learning and Preprocessing Methods

Deep learning is one of many methods in Artificial Intelligence (AI) that computers can use to process information like text, images, and audio. This manuscript will be focusing on image preprocessing, one of the many different techniques that are used to modify the neural network model training process, and how it affects the training speed and accuracy of the neural network. Six different image preprocessing techniques were picked for use in this study: Grayscale, Smoothing, Unmask Sharpening, Laplacian and Equalization, and Random Cropping and Rotation all of which were implemented using Python and the libraries NumPy, OpenCV, and PyTorch. For the dataset, a batch of 10000 images from the CIFAR10 dataset were used to train the model. This study explored the impact of preprocessing techniques on a deep learning model, employing the RESNET50 architecture. Notable improvements in model accuracy were observed, particularly with normalization and random cropping accompanied by rotation. The efficiency gains attributed to preprocessing were highlighted, leading to a more rapid training process and significant resource savings. This research underscores the importance of thoughtful preprocessing in enhancing the performance of deep learning models, offering valuable insights for practitioners in imageclassification tasks.
