Image Sharpness Configuration ACEUser's Guide, 3.6.x, 18316-000 Rev A Page 529 Object Definition Properties Show Results Graphics Specifies if the graphics are drawn in the Vision Window. Tool Links Image Source Defines the image source used for processing by this vision tool. Region of Interest (ROI) Offset Specifies the center and rotation of the ROI. X, Y, Degrees. Relative To Specifies the tool that will provide the input to this tool. The tool can be dragged from the Folder pane and dropped into this field. Search Area Defines the height and width of the region of interest.
Advanced Properties Bilinear Interpolation Enabled Specifies if bilinear interpolation is used to sample the input image. By default, bilinear interpolation is enabled because it improves accuracy. Custom Candidate Points Sets the maximum number of points that can be used by the tool to calculate the image sharpness. Custom Sampling Step When enabled, the tool uses the user-defined sampling step, instead of the default optimal sampling step, to sample the region of interest from the input image. Kernel Size Sets the size of the kernel of the operator for the sharpness process. The default setting of 5 (a 5x5 kernel) is generally sufficient for most cases.
Results Display Position Location of Image Sharpness Average in the dis- play pane. Standard Deviation Threshold Sets the minimum allowable Standard Deviation for a candidate point to be accepted as a meas- urement point.
