Improved YOLOv4 approach: A real time occluded vehicle detection
Open accessAbstract
A major challenge in computer vision is detecting and tracking vehicles in real-time.However, existing algorithms fail to detect vehicles at high speed and accuracy.Therefore, an algorithm that detects vehicles with higher accuracy is required for surveillance in traffic scenarios.This paper proposed an improved algorithm for vehicle detection based on YOLO (You Only Look Once) Version 4 through Convolution Neural Network (CNN) and Hard Negative Example Mining (HNEM) dataset in the training process to improve the accuracy of the vehicle detection.In the end, videos are used to detect vehicles using a deep learning technique called You Only Look Once (YOLO).The test results indicate good real-time performance and high detection accuracy of the proposed algorithm.Several parameters such as accuracy, precision, recognition recall, F1, and mAP have been used to measure the proposed algorithm's performance.The experiments have proved that the proposed algorithm achieved satisfactory performance in real-time due to occlusion and change in viewpoint.Finally, our proposed algorithm achieves improved precision, recall and mAP compared to the existing algorithms for occluded vehicle detection.

Kumar et al.'s YOLO-Kalman filter system was not efficient in real-time detection and tracking due to speed constraints.
“Kumar et al. [20] integrated the YOLO model with the Kalman filter to track the objects for counting.However, this system was not efficient in real-time detection and tracking due to the constraints in speed.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
