This paper introduces a novel image stylization method with the wireframe structure. Firstly, we divide the input image into multiple square cells of uniform size. The position of the highest and lowest points within each cell is determined and recorded by modeling the relationship between the cell height and grayscale values. Secondly, for each row of cells in the image, the highest and lowest points are sequentially connected with the highest and lower points of adjacent cells, respectively, forming an irregular wireframe envelope structure. Finally, black is filled within the envelope, producing a stylized grayscale image characterized by pronounced grayscale variations. Moreover, this method can be extended to color image stylization through color selection and filling techniques. Experimental results across various images demonstrate the effectiveness and practicality of this approach. The method is simple, efficient, and capable of producing high-quality results automatically in a short time. It offers a fresh perspective on image stylization and has potential applications in areas such as 3D printing, illustration design, and blind creation.
