What is the upper limit for feature size in EnhanceOrSup?

I am trying to enhanced features with a maximum pixel size of 250pixels. However, every time I run the pipline with these parameters it crashes at the EnhanceOrSuppressFeatures module. The pipeline runs (although very slowly) when I drop the feature size to 200 and below. Any idea how to get around this problem or am I stuck with this upper limit?

Thanks

Theoretically, there is no upper limit; however, practically speaking, once you get above 50 pixels or so, it does get quite slow.

If you are trying to enhance features that large, might it be better to use the Resize module to downsample your image and then enhance the resized image?
