Re: easy way to recognize handwritten character

hi,

Here is a method for breaking a complex chracter into simple ones for
an offline character.

It is based on the flow in the multiple direction.

I will just cut of a snippet of the algorithm here, but if any body
interested I can mail them the paper.


Method
-------
The method is to find the multiple flows and break then there.
------------------------------------------------------------------------
Take a recursive algorithm which moves over the character and break
the character where  every there is more than two options for the
flow.


Algorithm

WalkThoroughCharacter( currentpixel )
{

Remove currentpixel from the character; //this is necessary else the
recursive algorithm
                                                                   
will never end
        hasMoreThanOneFlow=false;

        If there is a pixel left of currentpixel
                Then
                        hasMoreThanOneFlow=true;

        WalkThoroughCharacter( pixel left of currentpixel )

        end if

        if there is a pixel right of currentpixel
                Then
                        If hasMoreThanOneFlow is true
    Then it is point of interesection where character has to be broken
Else
     hasMoreThanOneFlow=true;           
                        end if
        WalkThoroughCharacter( pixel right of currentpixel )

        end if
                if there is a pixel top of currentpixel
                Then
                        If hasMoreThanOneFlow is true
    Then it is point of interesection where character has to be broken
Else
     hasMoreThanOneFlow=true;           
end if

        WalkThoroughCharacter( pixel top of currentpixel )

        end if
        if there is a pixel down of currentpixel
                Then
                        If hasMoreThanOneFlow is true
    Then it is point of interesection where character has to be broken
Else
     hasMoreThanOneFlow=true;   
end if

        WalkThoroughCharacter( pixel down of currentpixel )
                
        end if
                
        
}


since the segments are also in sequence, and looking at these segments
this are just simple digits structures ,  and recognition of  simple
digits is easy. So we can recognize complex characters too in a simple
way.
