ABSTRACT:
In a figure recognition apparatus, a direction of a vector starting from a sample point most recently stored in a position data memory and terminating at an attention point is compared to an average value of directions of sample point vectors stored in the position data memory. The result of the comparison is used for deciding whether to discard the attention point.
