How to get the coordinates of each room in a floor plan image through object identification method?

One approach is to close all of the doors morphologically:

 

load('Walls')

e=ones(1,105);

A=imclose(imclose(~Image,e),e.');
B=imfill(A,'holes')&~A;

imshow(B)

Now, you can simply use regionprops to get all of the pixel coordinates in each room,

>> Rooms=regionprops(B,'PixelList')

Rooms = 

  3×1 struct array with fields:

    PixelList
