Abstract: Gastrointestinal (GI) diseases, including cancers and bleeding disorders, pose significant health risks worldwide, necessitating early and accurate diagnosis for effective treatment. Traditional diagnostic methods such as endoscopy and colonoscopy are time-consuming, require expert interpretation, and are prone to human errors. To address these challenges, this research proposes a novel deep learning-based framework for automated GI disease classification using Wavelet Enhanced Res-Google Feature Fusion Net (WERG-FFN) and Optimized Hybrid Serial-Paralleled Fusion (OHSP-Fusion). The proposed approach integrates Discrete Wavelet Transform (DWT) for enhanced feature extraction, combines ResNet50 and GoogleNet for deep feature representation, and employs Optimized Grey Sail Fish Optimization (OGSF) Algorithm for optimal feature selection. Finally, for the disease classification, a Linear Kernel Support Vector Machine (LK-SVM) is used which ensures robust and efficient disease categorization. Experimentation has been carried out by using the Kvasir-v1 containing images segregated into lower GI diseases such as polyps, dyed-lifted polyps, normal cecum, normal pylorus, and ulcerative colitis. The suggested technique attains accuracy rate of 99.79%.
