Individual Leopard Identification Using Black Spot Patterns

Leopards are critical apex predators within their ecosystems, and the precise identification of individual leopards is essential for effective conservation and management efforts. Traditional methods such as radio-collaring and physical marking are often cumbersome, time-consuming, and intrusive. To address this challenge, a novel approach involving a combination of Convolutional Neural Networks (CNNs) and image processing techniques has been employed in this research to individually identify leopards based on their distinctive black spot patterns. The research relies on a dataset consisting of high-resolution photographs of leopards taken in diverse locations, specifically chosen to encompass a range of individuals with unique spot patterns. Image processing algorithms, including Scale-Invariant Feature Transform (SIFT), were used to extract and analyze the black spot patterns on the leopards' coats. The YOLO Algorithm, integrated into the CNN, was employed to accurately segment and isolate the leopards within input images. The research has resulted in the development of a software system that offers a user-friendly web interface for uploading leopard images and conducting individual identification analyses. Field researchers and enthusiasts can submit photographs of leopards they encounter, and the system cross-references these images with an existing database to determine each leopard's identity. Impressively, the system consistently achieves an accuracy rate of approximately 92% in correctly identifying individual leopards based on their black spot patterns. The newly developed software system provides an effective, non-intrusive, and automated tool for enhancing wildlife management and conservation endeavors. This technology streamlines the process of monitoring and tracking leopards, enabling a deeper understanding of their behavior, geographic range, and population dynamics. Ultimately, this system plays a pivotal role in the formulation of precise and tailored conservation strategies.
