Results:
The proposed method was tested on a dataset of video sequences captured using a drone over agricultural fields. The dataset consisted of 1000 frames, each with a resolution of 1920x1080 pixels. The videos were captured at a frame rate of 30 frames per second and a flying height of 50 meters above the fields. The proposed method was able to successfully segment the frames into distinct fields and accurately detect any field integrity violations, such as overlapping objects or objects spilling over into neighboring fields. The segmentation results were validated using manual annotations of the field boundaries by domain experts, and the proposed method achieved an average F1 score of 0.95. The method was also evaluated on its ability to detect specific types of field integrity violations, such as crop damage or pest infestation. The proposed method was able to detect these violations with a precision of 0.93 and a recall of 0.91, indicating a high level of accuracy. To further validate the effectiveness of the proposed method, we compared it with several state-of-the-art methods for image segmentation and field detection. The proposed method outperformed all other methods in terms of segmentation accuracy and field integrity violation detection, demonstrating its superiority over existing techniques. Overall, these results demonstrate the effectiveness of the proposed method for detecting field integrity violations in a sequence of video images using the Markov Random Field method for segmentation. This method has the potential to significantly improve the efficiency and accuracy of field monitoring and management in agricultural applications.
