摘要：The Tangut script was a logographic writing
system used for the extinct Tangut language of the Western Xia
Dynasty spanned 1038 to 1227. To implement Tangut character
machine recognition is a research issue claiming practical value.
It is proposed in this paper to recognize Tangut character
based on 4 corners code, and Hough Transform is suggested in
the process of detecting the strokes of the character. Hough
Transform is one of the most used procedures in morphology
image processing, while for the purpose of character
recognition, revised measure is needed. Hough Transform with
Guidance of Endpoints (HTGE) was proposed in this paper to
accommodate the character recognition. Improvements of
HTGE: (1) Take advantage of endpoints to reduce the
computational burden of Hough transform. (2) Detect the
strokes with tolerance for the non-strictly straight line. (3)
Judge the straight line with consideration of length of the line
to avoid neglecting the short lines. Experiments results were
presented to verify the improvement of the HTGE.
