The skew-correction of scanned document image is a necessary step undergone before some processing. For the purpose of practical, robust, real-time of the algorithm, this paper presents a new skew-detection algorithm that based on the gray projection cyclostyle matching of Document Image. The algorithm, which is based on the analysis of gray scale projection curves of horizontal and vertical direction...
This paper presents an improved image retrieval algorithm which based on the gray projection cyclostyle matching to overcome the shortcomings of conventional content-based image retrieval methods. The algorithm based on the analysis that gray scale projection curves of horizontal and vertical direction of the images fully reflects the feature of gray distribution in the corresponding direction, then...
