WebTop-hat filtering computes the morphological opening of the image (using imopen) and then subtracts the result from the original image. J = imtophat (I,nhood) top-hat filters the image I, where nhood is a matrix of 0 s and 1 s that specifies the structuring element neighborhood. This syntax is equivalent to imtophat (I,strel(nhood)). WebTop Hat Commissioning Filters are typically deployed during the early stages of a gas installation and are designed to prevent system debris from entering the turbine or rotors of a gas meter during start up. The temporary use of a top hat (sometimes referred to as 'witches hat') commissioning filter is a vital way of protecting the internals ...
