Enabling more accurate bounding boxes for deep learning-based real-time human detection

Abstract

While human detection has been significantly recognized and widely used in many areas, the importance of human detection for behavioral analysis in medical research has been rarely reported. Recently, however, efforts have been actively made to recognize behavior diseases by measuring gait variability using pattern analysis of human detection results from videos taken by cameras. For this purpose, it is very crucial to establish robust human detection algorithms. In this work, we modified deep learning models by changing multi-detection into human detection. Also, we improved the localization of human detection by adjusting the input image according to the ratio of objects in an image and improving the results of several bounding boxes by interpolation. Experimental results demonstrated that by adopting the proposals, the accuracy of human detection could be increased significantly.
