Abstract

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.

Dependent claims

A reconfigurable module comprising:

an operational block including at least one adder/subtracter, at least one logic block, five inputs and three outputs,
the first output of the operational block being capable of delivering the following results:
the result of the addition of the first and second inputs of the operational block, or the result of the subtraction of the second input from the first input of the operational block, or the minimum of the first and second inputs of the operational block, or the maximum of the first and second inputs of the operational block,
the second output of the operational block being capable of delivering the following results:
the result of the addition of the fourth and fifth inputs of the operational block, or the result of the subtraction of the fifth input from the fourth input of the operational block, or the minimum of the fourth and fifth inputs of the operational block, or the maximum of the fourth and fifth inputs of the operational block, or the minimum of the first, second and fourth inputs of the operational block, or the maximum of the first, second and fourth inputs of the operational block,
the third output of the operational block being capable of delivering the following results:
the result of the addition of the first output and the third input of the operational block, or the result of the subtraction of the third input from the first output of the operational block
the result delivered by any of the first, second and third outputs depending on the type of operation performed by said at least one adder/subtracter and on the links established between the inputs and the outputs of said at least one logic block.
