General software features

This software implements a fast computing method for openings/closings by large linear morphological structuring element with an arbitrary angle. This method can be adapted to fast granulometry computations on the GPU and CPU. The results are obtained in stream with a single pass over the image, with a minimum of memory used. It is particularly suited to images of high resolution (HD).

Context in which the software is used

This software was used to obtain and validate the results published in the article [1].
