Hi, Basically, i want to detect an object (table) in the image and i'm using edge detection to detect the edge of the object. However, when i'm using edge detection, it produce a lot unwanted regions (produce a lot of points) other than the object itself. How to remove the unwanted regions, so that only the object of interest is appear?
