Project Group Name: open.dpg

Project Type:
    ADSP-BF533 [ ]
    ADSP-BF537 [ ]
    ADSP-BF561 [X]

Hardware Used:
    ADSP-BF561 EZ-Kit
    VisualDSP++ Emulator

System Services Components Used:
    None


OVERVIEW
========
The open function performs open operation  on the input binary image.
This is performed  by doing an erosion function, followed by a dilation
function. Temporary results after the erosion operation are stored on the
stack, and later used as input for the dilation operation.

For this function to work properly, the number of columns in the input
image must be an even number, aligned to a word or half word boundary.
The input image must not be stored in the same memory bank with the
structured elements.  The same structured elements are used for both
erosion and dilation operation.   The structured elements are stored
as shown below.

           | h00  h01  h02 |
           | h10  h11  h12 |
           | h20  h21  h22 |

Prototype:
    void open(unsigned char* in, int row, int col, short * SE, unsigned char *out );

Arguments:
     in   - pointer to the input image.
     row  - number of rows of input image.
     col  - number of columns of input image.
     SE   - pointer to 3x3 structured element.
     out  - pointer the output buffer.

Registers used : R0-R7, P0-P5.




RUNNING THE APPLICATION (on the ADSP-BF561 EZ-KIT Lite)
===========================================================

1) Load project group "open.dpg".

2) Select "Project->Rebuild Project"
