title: ZakynthosTurtles Dataset

description: Description:







The ZakynthosTurtles Dataset has been designed to support the development of numerical methods for the recognition and re-identification of individual sea turtles based on their unique scale patterns. Each turtle’s distinct scale arrangement provides a natural identifier, allowing researchers to track and study individuals over time. This dataset contains photographs captured in the wild, emphasizing the importance of non-intrusive wildlife monitoring techniques. The dataset includes 40 individual loggerhead sea turtles, with each turtle represented by four high-resolution photographs—both left and right profiles taken in two different years. This structure offers unique opportunities for investigating the stability and similarity of scale patterns over time and between opposite profiles.
