Grow homogeneous regions in an image, where the homogeneity is based on the region average. Click on the image to enter region seeds and fill values.

Region Seeds—Element numbers of pixels in the input image. These values are used as seed points for growing individual regions in the image.

Edit Value—Edit a selected value in the Region Seeds list.

Fill Values—Values to used to fill the regions grown. Fill values must be greater than 0 and less than 255. Default: 1, ..., n_regions where n_regions is the number of elements in the Region Seeds list.

Edit Value—Edit a selected value in the Fill Values list.

Delete Selected Item—Delete the selected value.

Clear List—Clears the Region Seeds and Fill Values list boxes.

Redraw—Redraws the selected seed points on the displayed image.

Max Iterations—The maximum number of iterations to be used in growing a region. A region is grown until either it converges (no more pixels can be added to the region) or Max Iterations is reached. (Default: 1000).

Threshold—A floating point scalar value that is the threshold around the region average used in determining whether or not a pixel belongs to a given region. A pixel is added to a region if adding it does not alter region average more than plus/minus the threshold value. (Default: 0.1)

Fill with Region Mean—If selected, each region is filled with the mean of the image pixels in the region.

Create New Image—Select this option to store the result in a new image variable.

Overwrite Image—Select this option to overwrite the original image with the result.

Variable Suffix—If the Create New Image option is selected, enter a suffix for the new image variable name. This suffix is added to the original variable name.

OK—Grow regions and exit the dialog box.

Apply—Grow regions, but do not exit the dialog box.

Cancel—Dismiss the dialog box without taking any action.

Help—Display online Help on the dialog box.
