Labview Image Processing

Algorithm given to me is like this.

Step 1: Capture image from a system
Step 2: Extract the region of interest.
Step 3: Select a row approximately in the middle of the membrane area.
Step 4: Determine the intensities at all the points across the membrane.
Step 5: Plot a graph of the intensities across the row (the line profile).
Step 6: Observe the minimum and maximum intensities along the row.

I need to construct the block diagram for this in labview. Please help me to do this. 

I am alresdy extracted the image and roi. how to do the remaining things?

Are you the same user  aradhrockzz@gm…  or differnt user logging from same PC?

-Post the vi/snippet which you developed and stuck with.

-What you are extracting?(Membrane area?)

-If the ROI has the membrane area then from the ROI bounding box(left, Top, Right, Bottom) which is rectangle you can caluclaute the middle row line points.

- Did you check the line profile example http://www.ni.com/example/30560/en/ ?

- ROI Profile gives the statistcis you want as min, max in the ROI : https://zone.ni.com/reference/en-XX/help/370281M-01/imaqvision/imaq_roiprofile/

Hope you have to try something by your own and get help in forum, else go through the examples/tutorials suggested by other users .

Its not good to expect a end solution based on your Flowchart, which wont help you to learn and even makes you lazySmiley Happy

That is not code at all. Just an image.
-You need to attach VI(.vi)
- Or LabVIEW snippet( how to create snippet http://www.ni.com/tutorial/9330/en/)
Thanks
