Labview Image Processing

[aradhrockzz@gmail.com]

I need to develope a program for extracting ROI of an image? How to do that?

Steps: Capture image from a system, Extract the region of interest,Select a row approximately in the middle of the membrane area of the image,Determine the intensities at all the points across the membrane, Plot a graph of the intensities across the row (the line profile). Please help me to do this. I am new in image processing. I am attaching front panel view of this.. I am not sure about whether this is correct or not. What is the block diagram for this system?

what do u want you want to achieve?

whats your input ?

what kind of image?

Is your ROI is fixed or you will select during run time?

Find the attached example

My input is an image (actually image path). It is an image taken by monochrome camera. From this image I need to select a row approximately in the middle of the membrane area. From that determine the intensities at all the points across the membrane. Then plot a graph of the intensities across the row(the line profile). I will select the ROI durng the run time. it is not fixed

If Possible share the source code you tried and the sample image.

- You can check the inbuilt examples: This example shows how to use the display tools to draw a line on the window that displays an image and get the pixel values of the image along that line (line profile).

- To navigate to examples: open LabVIEW and navigate to Help » Find Examples... » Toolkits and Modules.
