The polygon above is got after I shrank a rectangle. However, The meaningless branches are not desired. How can I remove them and split it into polygons that are independent to each other?

For illustration, the data of the polygon and an example figure is shown below, plotted by code:
plot(data(:,1),data(:,2),'bo-');

Well purely speculating, assuming you have a binary image with those lines:
FilledPolygons = imfill(PolygonImage,'holes');
OnlyPolygonsFilled = FilledPolygons - PolygonImage;
OnlyPolygonEdges = edge(OnlyPolygonsFilled);

You will need to clarify a bit more. Maybe show your actual data etc.

An example figure and its relevant data are appended below the question.
