Point LocationThe Point Location module provides a quick way to identify specific coordinates within the image based on their location. For example, you may want to know the position of the highest point of any non-black pixel within the image to identify a maximum peak. Note that this module operates on a binary image.
The module is often used after numerous morphological operations that have thresholded the image and changed the image shape.
Note that the north, south, east, and west points are calculated relative to the object's Center of Gravity point.
1. Location - Select each point that you would like to indicate with the image. Note that for each point a variable with a similar name is created with the X and Y coordinates of the point.
2. X,Y - Once Nearest X,Y and/or Furthest X,Y is selected the X and Y coordinate text boxes will be enabled. You can specify the X and Y coordinates of the point that should be used when comparing for furthest and nearest object points to the specified point. Keep in mind that the [expression] notation also applies in the text boxes.
3. Shape - The shape of the marker that indicates where a point has been sampled.
4. Color - The color of the marker that indicates where a point has been sampled.
5. Size - The size of the marker.
