The paper presents a novel method for suppression of the orthotropic stripe artifacts typical for sensitive opticaldetector arrays. The algorithm is based on the guided filtering technique where the guidance image is constructed fromthe input frame in a way that removes artifacts from local contrast structures while disregarding the low-frequencydistortions. The artifact suppression procedure was applied to the images of human faces taken with the IR -- THzcamera in the diagnosis of psycho-emotional states. In this case, the presence of orthotropic artifacts prevents digitalimage stabilization. We also demonstrated that adaptation of the algorithm to X-ray tomographic projections leads tosignificant suppression of ring artifacts in the reconstructed images.
