摘要：
The paper deals with the problem of correcting the intensity nonuniformity in magnetic resonance images. This problem is due to the peculiarities of the imaging equipment, may be caused by magnetic coils, and other technical reasons. In the paper, the method of removing such noise using ramp filter known also as the rho filter is considered. The numerical experiments on test images and real-world images of small animals are presented.
