Selecting Objects in a Binary Image
You can use the
bwselect function to select individual objects in a binary image. You specify pixels in the input image, and
bwselect returns a binary image that includes only those objects from the input image that contain one of the specified pixels.
You can specify the pixels either noninteractively or with a mouse. For example, suppose you want to select objects in the image displayed in the current axes. You type
The cursor changes to crosshairs when it is over the image. Click the objects you want to select;
bwselect displays a small star over each pixel you click. When you are done, press Return.
bwselect returns a binary image consisting of the objects you selected, and removes the stars.
See the reference page for
bwselect for more information.
