Parallel Template Matching for Faster Detection in Bioacoustics
摘要
This paper introduces a scalable approach to parallel template matching, designed to enhance detection speed in data-intensive bioacoustic research. While traditional template matching has proven useful due to its straightforward implementation and scalability, its limitations in concurrent large-scale application across numerous audio files demand high processing speed and robust technological infrastructure for timely analysis and results. The automated detection of acoustic events in large-scale audio datasets is crucial for effective biodiversity monitoring, particularly in the context of conservation efforts. By leveraging parallel processing techniques, we demonstrate significant reductions in processing time without compromising accuracy, enabling efficient utilization of existing hardware. This paper explores a computational strategy for applying template matching concurrently to large audio file volumes, evaluating various machine architectures and detailing the performance gains achieved through parallelization. Our findings suggest that the proposed approach not only addresses the challenges of processing vast amounts of data, but also expands the potential for near real-time and long-term monitoring of critical vocally-active species and the detection of other acoustic events of interest. This advancement represents a significant step forward in ecological monitoring and provides valuable computational insights for researchers and conservationists.
