I received the same error and cannot get around it. Seems like 3D structuring elements are not supported by gpuArray. If you discover anything in the future, please share.

Excellent catch. Your simplification is ~1.2x faster. The code is now updated.

Thanks for the function. Good code to have in your image processing toolbox.

great functions
thanks for the update

Very useful code. But when I tried to use it with the GPU array I encountered this hurdle:

'gpuarrayIM must be a gpuArray of type uint8 or logical. When used with a gpuarray, the structuring element must be flat and two-dimensional.'

Any idea if there is a way to sneak a 3D strel onto the gpu?
