The working group in Medical Image and Signal Processing (MISP) research center has set one of its goals to develop a reference medical image and signal database for image and signal processing research and development. The main aim of this collection is providing reliable datasets for researchers to compare their algorithms on common framework and to be able to interpret and compare the performance of their newly developed methods. The collected databases are devised to be in accordance with patient privacy and copyright issues. The ground truth is provided for datasets based on evaluation of one, two or three experts. Some datasets are collected from different modalities or from diverse anatomical structures of one patient. Most of the mentioned datasets are available with a published paper in famous journals to demonstrate possible application of the dataset.
