Use this function to remove or extract objects from the multiphase images based on a selected geometrical parameter. The function works by performing blob measurements on each object. If a computed parameter's value for a given object lies within the selected range, the object is identified as scrap and removed from the image. An alternative mode of the function extracts such objects and removes all other objects.

If you choose this command, the following options will become available:

Input

Displays the input image frame number. If you want to process another image, type or select the corresponding value.

Output

Displays the number of the frame in which the output image will be created. Depending on the Preferences. ImageWarp will set it either to the first available value or to the Input frame number. Type or select another value if you want the output image to be created in a different frame.

Preview

Select this check box to watch the Preview of the output image.

Parameter

Lets you choose one of the following parameters:

AngleMajor the angle between the major axis of the object and X-axis Pixels the number of pixels in an object Area the area of an object in calibrated units AreaBox the area of the bounding box of an object in calibrated units DCircle the diameter of the equivalent circle in caliblrated units AxisMajor the major axis of the equivalent ellipse in calibrated units AxisMinor the minor axis of the equivalent ellipse in calibrated units Perim the perimeter of an object in the calibrated units StartX the X-coordinate of the starting point of an object in pixels StartY the Y-coordinate of the starting point of an object in pixels EndX the X-coordinate of the endpoint of an object in pixels EndY the Y-coordinate of the endpoint of an object in pixels CenterX the X-coordinate of object's centroid in calibrated units CenterY the Y-coordinate of object's centroid in calibrated units Aspect the aspect ratio of the major axis divided by the minor axis Circularity the circular form-factor of an object Ellipticity the elliptical form-factor of an object Class the class ID of an object Count the ordinal number of a curve feature in the current session FeretX the length of the horizontal projection of an object in calibrated units FeretY the length of the vertical projection of an object in calibrated units MaxX the maximum X coordinate of an object in calibrated units MinX the minimum X coordinate of an object in calibrated units MaxY the maximum Y coordinate of an object in calibrated units MinY the minimum Y coordinate of an object in calibrated units YatMaxX the associated Y-value at the maximum X coordinate of an object YatMinX the associated Y-value at the minimum X coordinate of an object XatMaxY the associated X-value at the maximum Y coordinate of an object XatMinY the associated X-value at the minimum Y coordinate of an object

Min

Lets you choose the minimum value of the selected Parameter for an object to be identified as scrap.

Max

Lets you choose the maximum value of the selected Parameter for an object to be identified as scrap.

Mode

Allows you to choose the mode for the operation:

Click Remove to erase the objects identified as scrap from the image.

Click Select to extract the objects identified as scrap from the image.
