If you only have one figure to process, use edge() to detect the edge of the figure, then manually find the edge and use linear regression. If you have many figures to process, a line detection algorithm(such as hough transform) may be helpful.

Thank You for the suggestion, I have a folder of images to process hence will use the line detection algorithm.
