ABSTRACT -- This paper presents a method for extract skeleton vector from Thai print characters base on continuous sampling on character lines. The major techniques for skeleton vector is calculate point's direction on character lines [1]. But the recognition is not good enough because it still keep noises to be the feature. We correct this problem with continuously sampling on character line with junctions and then delete sample points that is not essential (not represent the sharp curve or sharp angle of line) after that calculate the direction of vectors. Data structure support multi objects character.
