From Image to Pixel

Hi!
I have a binary image that represents the map of a building. The white part represents the walkable area, while the black area represents the walls and non-walkable parts. Also in the white area I have 38 small points which represent some location inside the building. Given this image I would like to get the position in the binary matrix of these points(The pixel coordinates). Does anyone have an idea on how to do it in an efficient way? I am not really expert in handling images.
Thanks, Giovanni

How do you distinguish the "points" and the "walls/non-walkable area"? If your image is binary, both are black - correct?
Then the "points" have only one pixel, but no connection to another black pixel? Or are the "points" allowed to touch a wall on a side or diagonal?
I assume IMERODE can help you - if you have the image processing toolbox.
Inother words: Please explain the problem with more details.
