Abstract
Phenotyping plays a vital role in assessing the health traits of a plant. However, the process can become tedious and labour-intensive, especially when applied in a wide range of applications. Hence, an Unmanned Aerial Vehicle or UAV has been utilized due to its user-friendliness, high-resolution capabilities, and cost-effectiveness. Despite their advantages, UAV phenotyping Segmentation faces several challenges that can hinder the segmentation process and negatively impact recognition accuracy. Thus, an Enhanced Threshold-based Segmentation technique has been implemented, normalising image luminosity and improving both segmentation and recognition accuracy. Additionally, template matching was employed during the recognition phase, achieving perfect correlation when the Normalized Cross-Correlation (NCC) equals 1. Following normalization of the images, recognition accuracy improved by 5.25 percent, reaching an impressive 98.07 percent recognition accuracy at a distance of 4 meters. This advancement allows for more precise identification of unhealthy leaves, providing significant benefits to farmers and agriculturists by reducing time, effort, and costs associated with crop management.
