Abstract
A line thinning algorithm (LTA) for a grayscale input image, wherein the LTA is a separable algorithm that performs on each row of input grayscale image sequentially from top to bottom and subsequently on each column from left to right, independently. The LTA is very robust to the noise and is capable of thinning lines even in noisy image areas. The level of thinning is fully adaptive to the transition range and dynamic range locally in each line segment. Furthermore, the LTA for a black line can be easily generalized for a white line counterpart by simply switching the sign of one parameter DELTA from positive to negative without changing other aspects of the LTA.
