hello,
I am developing J2me application in which I want to calculate Shortest path between two locations.
I have used Google Static map api to get an image map.
1.Now I want to highlight path between two points.DO you have any idea how to highlight roads or extract roads between two locations.
2.I filtered road using rgb value of road pixel. As google maps gives image map with labels and street names,I am not getting completly filtered roads.So Is it possible to apply any image processing algorithm on this filtered road.
Please find here with attached filtered image.I need to fill the gaps between two points in the image.
Thank you.....
