i am tryin to make a code for script identification of from any handwritten indian document. this includes extraction of features of all the scripts. Urdu script has the feature of having a water reservoir.

i found this technique in a paper but cant work out the code. it said: scan the component from left to right (starting from top) to find the run of 1s whose upper pixels (north neighbor in the 4-neighbourhood sense ) are 0 – candidate run. Check whether it is possible to reach from an end point of a candidate run to its associated point by traversing the contour of the component. If one can reach from one end point of a candidate run to its associated point without passing any pixel lying above the rows of the current candidate run during traverse then a top reservoir is obtained from this end point.
