Research on Scalable Image Display Technology

分级图像显示是指利用单一信道传输可分级的多媒体信息的一种创新型显示技术,允许用单一版本的图像满足不同显示设备的显示需求。提出一种针对非数字图像的分级图像显示技术,主要思路是利用离散小波变换实现在灰度图像中嵌入不同类型的扩展图像信息,使客户可根据特定需求提取相应信息进行显示。技术框架允许以单一的灰度图像版本重建包括但不限于彩色图像、深度图像、热力图像等不同类型的图像。仿真实验表明,算法能有效重建彩色图像及深度图像,不仅重建的图像质量较高,而且嵌入信息对灰度图像的破坏也较小,算法运行速度快,实时性好。为分级图像显示技术提供了一种具体的解决方案,使分级图像显示成为可能,具有较好的市场应用前景。

Scalable image display is an innovative display technology that transmits scalable multimedia information in a single channel.It allows the use of a single version of the image to meet the display needs of different display devices.This paper proposes a scalable image display technology framework for non-digital images.The main idea is to embed different types of extended image information in gray-scale images by using discrete wavelet transform technology,so that customers can extract the corresponding information for display according to specific needs.This technical framework allows the reconstruction of different types of images including but not limited to color images,depth images,thermal images,etc.with a single gray-scale image version.Simulation results show that the algorithm can effectively reconstruct color images and depth images,with high quality and less damage to gray images.And the algorithm runs fast and has good real-time performance.The algorithm in this paper provides a specific solution for the concept of image hierarchical display,which makes image hierarchical display possible and has a good market prospect in application.
