Abstract:The calculation of weighted corner saturation gets the wrong location in text when the corners are over crowding, or the corners are insufficient. This paper solves the overcrowding of non-text corner by using the aspect ratio data (the ratio of exernal rectangular height and width), area ratio data (the ratio of white area and external rectangular area) of the candidate block as the eigenvalue.This text location equation is put forward with the combination of Binary linear regression. Using the numerical of regional block ratio area of high to width ratio of the text region is usually appear the poles distribution, it employs constant C1 in the locationequation to locate the text. Then, it adds constant C2 when value between the poles to locate the non-text. The experimental results show that this algorithm has achieved better effect than the method of calculating weighted corner saturation.
