Color Matching Output As Grayscale Image Indicates if the color image is converted to grey-scale after the color filters are applied. Region of Interest (ROI) The region of interest is the area in which the tool carries out its process. Most tool position parameters can be set through the region of interest section of the tool interface. The fol- lowing parameters define the tool region of interest. Offset Offset is the center of the ROI, defined by: Relative To Relative To specifies the tool that will provide the input to this tool. The tool can be dragged from the Tree structure and dropped into this field. Search Area Search Area is the size of the region of interest is defined by:
ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 461 Object Definition Custom Custom Sampling Step lets you set a sampling step value other than the default. To select a cus- tom sampling step, Enable must be checked. Increasing the sampling step value reduces l the tool accuracy and decreases the exe- cution time. Reducing the sampling step can increase l the tool accuracy but will also increase the execution time.
