the segmented area.
Choose Segmentation command on a True Color image, select either Red(R),
Green(G), or Blue(B) channel to do the operation.

Binary is a kind of gray level process. If the gray of the pixel is greater than the given
threshold, the pixel's color will be changed into white. Otherwise, the pixel's color will

The curve on the Binary dialog shows the gray distribution of the image.
The line in the dialog indicates the threshold value. Drag the line to change the
