A Method of Character Feature Extraction of Scrap Paper Image Mosaics
Wang Ron · Science Technology and Engineering · 2014
Feature extraction is the key of scrap paper image mosaics including character,which affecting the effect of mosaics.A method of character feature extraction of scrap paper image is proposed.Firstly,the original scrap paper images are preprocessed to get the character binary image and the scrap paper background binary image respectively.Secondly,the single pixel edges of character and scrap paper background are extracted by using edge detection operator.Finally,the crossing point of character and the edge of scrap paper background is detected by using structure operator,and the direction feature of character edge is also extracted according to the crossing point information.The simulating experimental results show that the character feature extraction method proposed in this paper is reasonable,which can extract the character feature of scrap paper image quickly and correctly,laying a foundation for the subsequent image mosaics.
