Enhanced pedestrian detection using optimized deep convolution neural network for smart building surveillance

Abstract

Pedestrian detection and tracking is a critical task in the area of smart building surveillance. Due to advancements in sensors, the architects concentrate in construction of smart buildings. Pedestrian detection in smart building is greatly challenged by the image noises by various external environmental parameters. Traditional filter-based techniques for image classification like histogram of oriented gradients filters and machine learning algorithms suffer to perform well for huge volume of pedestrian input images. The advancements in deep learning algorithms perform exponentially good in handling the huge volume of image data. The current study proposes a pedestrian detection model based on deep convolution neural network (CNN) for classification of pedestrians from the input images. Proposed optimized version of VGG-16 architecture is evaluated for pedestrian detection on the INRIA benchmarking dataset consisting of 227 × 227 pixel images. The proposed model achieves an accuracy of 98.5%. It was found that proposed model performs better than the other pretrained CNN architectures and other machine learning models. Pedestrians are reasonably detected and the performance of the proposed algorithm is validated.
