With the continuous progress of society and the development of economy, the packaging design has also become a fierce competition for eye-catching products and because of the situation of more and more fierce competition of similar products, it prompted more and more designers to start a new Examining of their own national traditional ink art, which hope to absorb nutrients from traditional cultural elements, so as to enhance the cultural connotation and unique personality of the product, and this traditional ink art is the emotion with a long history accumulated in the hearts of the public. It has guided the public's lifestyle and aesthetic trends for a long time. The inheritance and transcendence of traditional ink art has become the only way to explore and develop national characteristic packaging design. Starting from the processing of ink image primitives, this paper analyses the pixel colour segmentation algorithm of ink image, extracts various elements and length and width parameters of ink image for line rendering based on packaging design, and calculates the vectorisation of ink image through bilinear difference algorithm. The latter design parameters are used to highlight the artistic design effect of the ink-wash style packaging.
In order to increase the image quality of visual communication posters and to solve the problems of uneven pixel distribution, distortion, and poor visual effect caused by the lighting environment, an image filtering method, with features based on wavelet and block homomorphic, is proposed on the basis of homomorphic filtering. According to the component change defect of red, green, and blue (RGB) color space, the image color space that needs to be processed is converted into HSV form and then processed in blocks. At that moment, the wavelet transform method is applied to replace the traditional Fourier transform in the block homomorphic filtering to decompose the luminance component. Furthermore, subimages that are decomposed by the wavelet are divided into blocks and then subjected to high-pass filtering so as to obtain a clear image. The investigational outcomes express that the proposed algorithm has an obvious enhancement effect on the visual communication poster image under the variable illumination situation. Furthermore, the suggested technique effectively rectifies the overall brightness of the image and significantly advances the detail contrast of the visual communication poster image. The signal-to-noise (SNR) ratio of our algorithm at different bit rates is higher than that of the LICE and CIE methods. Similarly, the enhancement impact demonstrates that the image statistical parameters of our algorithm are substantially better than those of the LICIE and CIE methods.
In today’s era, sensing technology has been very developed in the fields of machinery, medicine, safety monitoring, and so on. In order to be applicable to more fields, new sensing technologies are also evolving. Tactile and sensory states are two important indicators of human induction to external things. Based on the contact force information between fiber Bragg grating tactile sensor and human body, this paper uses a new fiber Bragg grating tactile sensing system to study the artistic elements of ink painting in modern graphic design. Subsequently, the structure and specific performances of the sensor experimental data are analyzed. With its small volume, low cost, high sensitivity, and good compatibility with the observed body, the new fiber Bragg grating tactile sensor will not be affected by external electromagnetic interference, various noise signals, complex integration, and other problems. According to the data observed by ink painters in this paper, the new tactile sensing technology of fiber Bragg grating can well control the external interference factors. In general, the technology is of great social and practical value.
