The increase in melanoma incidence has recently prompted the development of computer-aided diagnostic systems for dermatoscopic image classification. The PH² dataset was developed for research and benchmarking purposes to facilitate comparative studies of segmentation and classification algorithms for dermatoscopic images. PH² is a database of dermatoscopic images obtained from the Dermatology Service at Pedro Hispano Hospital in Matosinhos, Portugal. This dataset contains 200 dermatoscopic images along with corresponding annotation images, all stored in PNG format. Analysis and evaluation of the PH² dataset can help researchers understand and verify the performance of proposed systems in real-world dermatological scenarios, providing a foundation for further research and innovation in the field of skin disease diagnosis.

The PH² dataset consists of two main directories: images
and masks
. The images
directory contains the original images, and the masks
directory contains the corresponding segmentation annotation images.
