The depth-based refinement in SegMinD may have limitations in scenarios where the depth information is noisy or inaccurate, leading to suboptimal performance in identifying the central path of the row. To address this in future work, several strategies can be considered:
Improved Depth Sensing: Enhancing the depth sensing capabilities of the camera system by using higher-resolution depth sensors or integrating multiple sensors for redundancy and improved accuracy.
Noise Reduction Techniques: Implementing noise reduction algorithms to filter out erroneous depth measurements and improve the reliability of the depth information used in the segmentation process.
Adaptive Depth Thresholding: Developing adaptive depth thresholding techniques that dynamically adjust the depth threshold based on the specific characteristics of the environment, such as the density of vegetation or the distance to the row.
By addressing these potential limitations, the SegMinD algorithm can achieve better performance and robustness in challenging agricultural environments with dense vegetation.
