Faster R-CNN Deep Learning Model for Pedestrian Detection from Drone Images

Abstract

Pedestrian detection from a drone-based images has many potential applications such as searching for missing persons, surveillance of illegal immigrants, and monitoring of critical infrastructure. However, it is considered as a very challenge computer vision problem due to the variations in camera point of view, distance from pedestrian, changes in illuminations and weather conditions, variation in the surrounding objects, as well as present of human-like objects. Recently, deep learningbased models are getting more attention, and they have proven a great success in many object detection problems such as the detection of faces, breast masses, and vehicles. As such, this work aims to develop a deep learning-based model that will be applied for the problem of pedestrian detection from a drone-based images. Particularly, faster region-based convolutional neural network (Faster R-CNN) will be used to search for the present of a pedestrian inside the captured drone-based images. To assess the performances, a total of 1500 images were collected by S30W drone and these images were captured at different places, with various views and weather conditions, and at daytime and night-time. Results show that Faster R-CNN was able to achieve a promising result with 98% precision, 99% recall, and 98% F1 measure. Further analysis has been conducted by comparing the outcomes of Faster R-CNN with YOLO deep model on UAV123 publicly available dataset. The reported results indicated that both detection models almost reported very similar results.

“…For energy conservation and pollution reduction, the solution of blast furnace slag smelting problem is more inclined to use the theoretical model to predict the melting behavior in the blast furnace slag. Convolutional neural network (CNN) [31]- [34], region convolutional neural network (R-CNN) [35]- [37], fast R-CNN and support vector machine (SVM) [38], [39] have become popular in the field of target tracking and positioning [40], [41]. CNN and other methods have been used to extract the depth features and adaptively fuse them [42].…”

“…This section includes the use of different techniques and deep learning models for the detection of different objects, among which one research by [17] focuses on the smoke produced by Gunfire to detect the location of the fired Gun. Other research work done by [18] includes using the Faster-RCNN model to detect objects and pedestrians. Support vector machine (SVM) was used by [19] to do real-time clothing recognition from surveillance videos.…”
