This function is dedicated to reduction of noise in images, more specifically medical images. Images with a great amount of periodic noise in them are better suited to be clarified using this filter.
The number of iterations controls the number of times the filter will be performed on image. The lower the variable is, the faster the filter will perform. Higher iterations typically means clearer results, yet it depends on the maximum length of vectors that can be computed from the image to obtain the best results
The higher the time step variable is, the larger of a range of vectors is used for the next iteration, yet too high a value, will yield out of range results as it will exceed the maximum vectors at some spots
The variable update is very useful when using a large number of iterations on a large image, especially when the results are not known. This variable, updates the image every number Update iterations, thus the progress of the de-noising can be witnessed. If the image has a region, the function will be performed on the region only.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available in the Document and Medical Imaging toolkits.s
