Hi, I want to draw two lines on image automatically. For your reference I have drawn those lines manually marked with green and violet colors using imline function as shown in matlab. Can anyone help me in this. Any help is much appreciated!!

Thank you @Image Analyst for your response.

No I don't want anything user to manually draw a line and return the endpoints so you can draw a line. I want to get the end points to draw line automatically. I have drawn those violet and green lines using imline function only. And drawline(), or improfile() won't solve my problem.

Yes I don't want the user to manually draw anything, that is why I want help or some ideas what can be taken into considereation from that defect part to draw lines. Like if there is any method or way I can get the coordinates of the image as my defect part is on white background. Is there any way that code will give coordinates where it will find value except 255.

The purple line drawn there and not at a location shifted 20 pixels downward because I am working on the industrial project of the automated inspection of the panel images. And the defect was present on the green data lines which will lead to short circuit. So, our task is basically to seperate the defect present on the green data lines. Therefore I need to draw lines only on green part so that i will generate a path for the laser cutting.

Here I have attached the original panel image, defect seperated from the panel image and I have already posted above the image where i have manually drawn the violet and red lines which should be done automatically rather than any user interaction.
