Reconfigurable module and method of implementing this reconfigurable module for performing morphological operations

摘要

The invention provides a reconfigurable module allowing morphological operations to be carried out for image processing. The module includes an operational block having five inputs, three outputs, three adders/subtracters and four logic blocks. The logic blocks provide various routings between the three adders/subtracters to enable the outputs to deliver the result of basic operations carried out on the five inputs. The reconfigurable module has a reduced number of components while at the same time allowing various morphological operations to be performed whose parameters can be modified. Furthermore, the reconfigurable module is serially combined to carry out more complex morphological operations. The invention also provides a method for implementing the reconfigurable module allowing an integral image, an eroded image, an expanded image, a distance image or projections along the rows and columns of the original image to be determined starting from an original image.
