Abstract


Sublimation image editing Jacquard CAD software, based on the vector image editing Jacquard Jacquard CAD software image editing operation for bitmap-based vector jacquard image editing is the vector of operation. Vector-based image editing software Jacquard computer graphics and image processing technology, combined with a practical software platform jacquard image process requirements, and to optimize the operation of human-computer interaction. Vector's move, zoom, rotate, copy, change properties are easy to operate, and vector graphics, whether to enlarge, shrink, or rotate without distortion. Vector-based jacquard image editing software provides quick graphical editing tool for image reconstruction and image zoom operation more flexible image editing operations. Based vector jacquard image editing software, image input, image preprocessing, image vectorization, vector editing and image input of five modules. In this paper, a more reasonable algorithm in jacquard image vectorization process. 1 jacquard image pre-processing, including image color quantization and noise processing. In color quantization part with a palette-based color quantization method to improve the computing speed. Noise for a true color image processing, using a new filter - noise pixel detection-based adaptive vector filter, have a good effect. Jacquard image the regular algorithm: the image regularity algorithm for image Jacquard Jacquard eliminate the eight-connected image. Avoid jacquard weaving process, the image exists more eight-connected points, and thus yarns prone interleaving, staggered excessive condition. In addition, the algorithm improves the the boundary extraction efficiency. 3 the the boundary inflection point of the outline of the image, Hough improved algorithm to outline boundary inflection point determination, improved Hough transform algorithm parameter space can be divided into the more detailed, the inflection point is more accurate, stable. Image contour control points, selection of fitting a straight line and cubic B-spline curve is the combination of the to reverse control points. Weave the smoothness of the image boundary, and to improve the image quality. Image editing part, this paper structure modes in the combined mode, \Store data using a doubly linked list implementation, a series of variables defined in the head of the list node makes the vectorized image editing more flexible.
