Summary

This view provides an easy interface to quickly compute some features of a whole image or a region of interest.

This document will tell you how to use this view, but it is assumed that you already know how to use MITK in general.

Please see Details for more detailed information on usage and supported filters. If you encounter problems using the view, please have a look at the Troubleshooting page.

Usage

After loading of an image or a binary mask of an image in the datamanager, the Image Statistics view shows some statistical information on the selected image. If a mask is selected, the name of the mask and the name of the image, to which the mask is applied, are shown in the respective combo boxes. For time data the current time step is used for the selected mask and the selected image. If the total number of time steps on the selected mask is less than the current time step, the last time step of the mask is used. If a mask is selected, its used time step will be displayed next to its name like this: (t=0).

Check "Ignore zero-valued voxels" to hide voxels with grayvalue zero.

Below it is the statistics window which displays the calculated statistical features (such as mean, standard deviation...).

Beneath the statistics window is the histogram window, which shows the histogram of the current selection.

At top of the histogram window are two checkboxes, one "Show Subchart" and other is "Use default bins". Below that is #bins spinbox. One can uncheck the "Use default bins" checkbox to change the number of bins.

Use mousewheel to zoom in and out the histogram. With the left mouse button the histogram is pannable in zoomed state.

If the histogram is displayed as a barchart a tooltip is available by hovering over one of the bins. A tooltip is also available, if an intesity profile is created for a path element as mask.

At the bottom of each view is one button. They copy their respective data in csv format to the clipboard.

Troubleshooting

No known problems.

All other problems.
Please report to the MITK mailing list. See http://www.mitk.org/wiki/Mailinglist on how to do this.

Beneath the statistics window is the histogram window, which shows the histogram of the current selection.

Draw a rectangular window with pressed left button to zoom the histogram view in. With a double click in the view area you can zoom out to the default viewport. You can also just pan the view in horizontal or vertical direction by dragging with the left mousebutton in the respective direction.

If the mask is not a closed planar figure or a segmentation an intensity profile is created instead of the histogram.

A tooltip is available by hovering over one of the bins.

At the bottom of each view is one button. They copy their respective data in csv format to the clipboard.
