Application of image processing technology in the digital media era in the design of integrated materials painting in installation art

In response to the problems of lack of intelligence, low recognition, loss of brightness, and unclear design objects in the comprehensive material painting of installation art, when materials enter the field of artistic creation, they can assist in artistic creation, but constantly updating materials is also a challenge for artists. This article utilized image processing technology in the digital media era to develop a comprehensive material painting design system for installation art. The aim was to use image processing technology to intelligently restore brightness balance, enhance restoration, and denoise paintings in integrated material painting, thereby improving the problems in installation art integrated material painting. In order to demonstrate the effectiveness of the designed installation art comprehensive material painting design system based on image processing technology, this article conducted relevant tests on the design system. The test results showed that the brightness of the 5 sample paintings without image processing technology was relatively dim. The brightness of character painting was the brightest compared to the 5 sample paintings, at 47.13%; the landscape painting had the lowest brightness, at 36.61%. The brightness of the five sample paintings processed by image processing technology significantly improved, and the brightness of all sample paintings reached over 70%. From this, it can be seen that the design system can effectively improve the quality of integrated material painting in installation art, and can also enhance the brightness of integrated material painting in installation art. Moreover, it can ensure a certain degree of recognition and clarity, and the design system has a high level of intelligence. This article hoped that the application of image processing technology in the digital media era in the comprehensive material painting design of installation art can effectively promote the improvement and upgrading of installation art comprehensive material painting design, and inject technological strength into the application of installation art in the comprehensive material painting design. This article can provide reference value for the design and development of installation art and comprehensive material painting.
