confocal endoscopy

For comparing the performance of IQA methods, a database of confocal endoscopy image obtained in practical imaging conditions is proposed. There are 642 grayscale images with authentic distortion of 1024 × 1024 pixels in the database. Quality of the images were rated by 8 experienced researchers in operation and image processing of confocal endoscopy by the range of 1-5, where 1 denotes the lowest quality and 5 denotes the highest quality. Finally, the MOS of the images was computed by averaging the scores of the researchers.
