  <abstract>Coffee, a globally traded agricultural commodity and one of the most consumed beverages  worldwide, plays a significant role in generating millions of jobs and income. The expansion of  the coffee industry driven by increased consumption and demand for specialty coffee necessitates  innovative methods for accurately identifying and classifying coffee plant varieties. Traditional  approaches based on physical characteristics and chemometric techniques face challenges as the  number of coffee varieties grows. The study aims to investigate the viability of utilizing images  captured by unmanned aerial vehicles (UAVs) with high-resolution sensors for images processing  techniques. This involves the collection, processing, and analysis of real-time drone imagery to  identify different coffee plant varieties. Moreover, the research focuses on the development and  optimization of deep learning algorithms, particularly Convolutional Neural Networks (CNNs),  tailored specifically for discerning unique features of various coffee plant varieties. CNNs belong  to deep neural networks that have proven highly effective in various computer vision tasks, such  as object detection, image classification and image segmentation. By integrating advanced  technologies such as UAVs and CNNs, the study seeks to enhance the efficiency and accuracy of  coffee variety classification, offering potential advancements for the coffee cultivation sector. The  CNNs model achieved an 89.1% training accuracy, 67.8% validation accuracy, and an overall  predictive accuracy of 67.06%. These results demonstrate the effectiveness of employing advanced  computer vision techniques for coffee variety classification using drone-captured imagery. This  study offers a promising decision support algorithm for the classification of coffee plant varieties,  contributing to the enhancement of the coffee cultivation sector. By revolutionizing the coffee  industry through technologically advanced and efficient solutions, this research addresses the  challenges associated with the growing diversity of coffee varieties. </abstract>
