Abstract:
1. A system that extracts information which characterized text lines in an image, comprising: an input component for receiving a bitmap of an input image that includes text lines; and a parameterizing engine that determines a base-line for at least one text line in the image by finding a parametric curve that maximizes a fitness function that depends on values of pixels through which the parametric curve passes and pixels below the parametric curve, wherein the base-line corresponds to the parametric curve for which the fitness function is maximized, wherein the fitness function is defined as fitness(baseline) and is equal to where: x and y are horizontal and vertical pixel coordinates respectively; img[y, x] is a pixel value of the bitmap at location (y, x); width is a width of bitmap input image; and baseline[x] is a y-coordinate of the base-line at position x.
