Abstract [eng] |
Nowadays, the engineering application of vehicle detection from aerial images is a challenging task due to the particularity of perspective, the small size of the objects, and the complex background. This research aim is to investigate low-resolution aerial images of vehicles that can be utilized for vehicle detection using machine learning models. The research work was conducted using one-stage deep learning-based object detection algorithms YOLOv5, YOLOv7, and YOLOv8 on the two datasets (COWC and VEDAI) that addressed the task of small vehicle detection. For the training of the models, available pre-trained weights were used as a starting point, and then each model was trained by utilizing transfer learning. The obtained results of the study demonstrated that by reducing the image pixel ratio every 5 cm per pixel from 12.5x12.5 to 27.5x27.5 cm per pixel, the accuracy of the object detection models decreases by an average of 3.51%. When the pixel ratio varies from 30x30 to 32.5x32.5 cm per pixel, the accuracy of the models drops by an average of 2.33% on the COWC dataset and 42.4% on the VEDAI dataset. |
