Advanced AI techniques for video classification: a comprehensive framework using multiple feature extraction and classification methods

Abstract

The increasing popularity of multimedia applications, such as video classification, has underscored the need for efficient methods to manage and categorize vast video datasets. Video classification simplifies video categorization, enhancing searchability and retrieval by leveraging distinctive features extracted from textual, audio, and visual components. This paper introduces an automated video recognition system that classifies video content based on motion types (low, medium, and high) derived from visual component characteristics. The proposed system utilizes advanced artificial intelligence techniques with four feature extraction methods; MFCC alone, (2) MFCC after applying DWT, (3) denoised MFCC, and (4) MFCC after applying denoised DWT. And seven classification algorithms to optimize accuracy. A novel aspect of this study is the application of Mel Frequency Cepstral Coefficients (MFCC) to extract features from the video domain rather than their traditional use in audio processing, demonstrating the effectiveness of MFCC for video classification. Seven classification techniques, including K-Nearest Neighbors (KNN), Radial Basis Function Support Vector Machines (SVM-RBF), Parzen Window Method, Neighborhood Components Analysis (NCA), Multinomial Logistic Regression (ML), Linear Support Vector Machines (SVM Linear), and Decision Trees (DT), are evaluated to establish a robust classification framework. Experimental results indicate that this denoising-enhanced system significantly improves classification accuracy, providing a comprehensive framework for future applications in multimedia management and other fields.
