16.9 Load file “p_16_9.jpg” and display. Figure “p_16_9” shows a combined
M-mode and Doppler image of venous blood flow. The blood flow in “p_16_7.
jpg” is shown in blue in the upper half of the image, while the bottom section
displays the flow velocity characteristics as a function of time.*
a. Use the seed growing algorithm to find the perimeter of the vein using
seed and region growing techniques described in Section 4.3. Visually
choose some suitable seed points to start the process.
