Noise removal in IR (Infra Red) images is very popular in recent years, however the same approach is utilized as for vision images, with no or minor changes. In this work we wanted to show the results of noise removal for selected filters. We focused on investigation of some filters normally used for image processing and their influence to IR image quality. In IR imaging the choice of filter depends mainly on the purpose of the processing, e.g. detection of small objects in complex images, edge and contour detection or removal of non-uniformity of the detector array. The performance of the selected noise reduction filters was evaluated using PSNR (Peak Signal-to-Noise Ratio) and MAE (Mean Absolute Error) quality measure, greater value of the PSNR and lower value of the MAE indicate better noise reduction. The results are shown only for few images from our database which contain over 2000 of IR images.
