Enhanced Classification System for Real-Time Embedded Vision Applications

Abstract

Embedded computer vision systems are increasingly being adopted across various domains, playing a pivotal role in enabling advanced technologies such as autonomous vehicles and industrial automation. Their cost-effectiveness, compact size, and portability make them particularly well-suited for diverse implementations and operations. In real-time scenarios, these systems must process visual data with minimal latency, which is crucial for immediate decision-making. However, these solutions continue to face significant challenges related to computational efficiency, memory usage, and accuracy. This research addresses these challenges by enhancing classification methodologies, specifically in Gray Level Co-occurrence Matrix (GLCM) feature extraction and Support Vector Machine (SVM) classifiers. To maintain a high level of accuracy while preserving performance, a smaller feature set is selected following a comprehensive complexity analysis and is further refined through Correlation-based Feature Selection (CFS). The proposed method achieves an overall classification accuracy of 84.76% with a feature set reduced by 79.2%, resulting in a 72.45% decrease in processing time, a 50% reduction in storage requirements, and up to a 77.8% decrease in memory demand during prediction. These improvements demonstrate the effectiveness of the proposed approach in improving the adaptability and capabilities of embedded vision systems (EVS), optimizing their performance under the constraints of real-time limited-resource environments.
