Study on Intelligent Image Analysis of Bitmap Vectorization Conversion in Graphic Design with Pattern Fusion

This paper takes the intelligent image analysis of the vectorized conversion of bitmaps in graphic design as the main line. Aiming at the situation that it is not easy to make three-dimensional pictures in graphic design, the intelligent image analysis algorithm is used to extract, analyze and classify the features of bitmaps. Based on the Bézier curve-based graphics boundary line extraction, graphic boundary line extraction correction and simple color graphic boundary line extraction models, use Excel for corresponding data processing, and use Photoshop, Matlab and other software to extract the graphic boundary lines. Opencv software the fitted line was tested, and the result showed that the conversion efficiency of bitmap vectorization increased by 9.1%.
