Module Description

The SimpleFilters module provides a simple interface to hundreds of basic and advanced filters from ITK.

The algorithms available include binary morphology, grayscale morphology, denoising, thresholding, image intensity manipulation, region growing, FFT, and many advanced algorithms.


Panels and their use

Panel for SimpleFilters

The panned for SimpleFilters is modeled after the Command Line Modules.

At the top the Filters section enable the selection of one of the hundred of filters available. The Search text box is use quickly find a filter based on it's name.

The top of the Parameters section dynamically changes based of the Filter selected above, it presents a list of input filter and parameters which the filter needs. Along with the output image for the filter. The behavior of the output is modeled after the CLIs.

At the bottom it features an Apply to run the filter, an Abort button to cancel a actively running filter, and a Restore Defaults to revert the parameters to their initial settings. Above that is the status and progress if a filter is active.


Tips

The output image for the filter can be a gray scale image or a label map. The "LabelMap" check box should be selected to ensure the image is displayed correctly with in Slicer.

Most filters which take more than one image as input expect that the filters be the same pixel type, and the images occupy the same physical space.



Use Cases

There are a large number of filters available in the SimpleFilters module. The following is a table of the filter name, a brief description, and a link to the underlaying ITK filter. The ITK link contains additional detail about using the filter.

to Edge Detection"(IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol. PAMI-8, No.6, November 1986), there are four major steps used in the edge-detection scheme: (1) Smooth the input image with Gaussian filter. (2) Calculate the second directional derivatives of the smoothed image. (3) Non-Maximum Suppression: the zero-crossings of 2nd derivative are found, and the sign of third derivative is used to find the correct extrema. (4) The hysteresis thresholding is applied to the gradient magnitude (multiplied with zero-crossings) of the smoothed image to find and link edges.
