I have some images that are difficult to detect the edges but I only need some simple selections done. I have written something that I can use ginput to outline the edge I wish to make but looking if there is any way to correct it using an edge detection, kind of line snapping a line to a grid?

This is exactly what active contours, or snakes, were originally designed for. If you have the Image Processing Toolbox, have a look at activecontour.
