Abstract

Manual inspection of locally made earthen ceramic pots suffers from inconsistency and subjectivity, creating problems for quality control in traditional pottery production. This research examines how denoising affects feature extraction in SVM-based ceramic pot classification. The study compares three deep learning denoising architectures: the Denoising Autoencoder with Convolutional Autoencoder (DAE-CAE), Denoising Convolutional Neural Network (DnCNN), and a Generative Adversarial Network (GAN). PSNR, SSIM, and RMSE as metrics were used for performance evaluation. Results show that the DAE-CAE Model outperforms the other architectures, achieving a PSNR of 23.2087, SSIM of 0.4828, and RMSE of 0.0713, while DnCNN reaches 23.0786 PSNR, 0.4742 SSIM, and 0.0725 RMSE, and GAN achieves 23.1815 PSNR, 0.4784 SSIM, and 0.0719 RMSE. Features extracted from DAE-CAE-denoised images are used to train classifiers, and SVM achieves 93.23% accuracy. This exceeds both Random Forest at 90.73% and CNN at 90.20%. The results indicate that denoising improves classification generalizability, precision, and reliability. The DAE-CAE-enhanced SVM framework proves most effective for this task. Combining deep learning denoising with SVM provides a practical automated alternative to manual inspection, offering both improved accuracy and potential for scaling quality assessment in traditional ceramic production.
