Long Description

This application performs binary morphological operations on a mono band image or a channel of the input.

Parameters

• Input Image (in): The input image to be filtered.

• Output Image (out): Output image

• Selected Channel (channel): The selected channel index

• Available RAM (Mb) (ram): Available memory for processing (in MB)

• Type of structuring element (structype): Choice of the structuring element type

  • Ball (ball):

    • Structuring element X radius (structype.ball.xradius): The structuring element radius along the X axis.

    • Structuring element Y radiuss (structype.ball.yradius): The structuring element radius along the y axis.

  • Cross (cross):



• Morphological Operation (filter): Choice of the morphological operation

  • Dilate (dilate):

    • Foreground value (filter.dilate.foreval): Set the foreground value, default is 1.0.

    • Background value (filter.dilate.backval): Set the background value, default is 0.0.

  • Erode (erode):

    • Foreground value (filter.erode.foreval): Set the foreground value, default is 1.0.

    • Background value (filter.erode.backval): Set the background value, default is 0.0.
