Remarks

Despeckle is the process of removing random specks of noise from an image. This method examines the current image to find objects meeting the current criteria for specks and then removes them. If no parameters are provided, the defaults are used.

Output

If no errors occur, ImagXpress despeckles the current image. If the despeckle operation is not performed for any reason, the current image is not modified.
