Acceleration of Image Segmentation Algorithm for (Breast) Mammogram Images Using High-Performance Reconfigurable Dataflow Computers

Algorithm 2

Pectoral muscle removal algorithm.

Step 1.  Start with the first row;

Step 2. Scan from left to right side;

Step 3. While pixel value is less than the threshold value go to the

   next pixel;

Step 4.  If the pixel belongs to the first tenth part of the

   mammogram then the pixel value is greater than or equal to

   the threshold value set the current pixel value to black and

   go to the next pixel and repeat Step , otherwise go to Step

   ;

   If the pixel does not belong to the first tenth part of the

   mammogram anymore go to Step ;

Step 5.  If the pixel value is greater than or equal to the threshold

   value and the above pixel is black then set the current pixel

   value to black and go to the next pixel and repeat Step ,

   otherwise go to Step ;

Step 6.  Repeat Steps to for the next row.
