基于虚拟现实的多媒体图像重构

Multimedia image reconstruction based on virtual reality

为解决传统图像重构方法存在的质量差、速度慢、耗费时间长等问题,提出基于虚拟现实的多媒体图像重构方法。分析图像网格数据表示情况,引入小波技术对虚拟现实中的多媒体图像进行分解,量化编码图像,将视觉点与图像间距离作为度量,选取阈值,对图像进行压缩,获取不同质量的多媒体图像资源,根据虚拟现实场景度量对不同资源进行分类,完成多媒体图像重构。实验结果表明,相同情况下重构50张图像,所提方法耗时150s,相较于传统方法耗时缩短了100s,其重构速率平均达到70%,清晰度也有极大的改善,可得出该方法重构质量高、速度快、清晰度高。

In order to solve the problems of poor quality, slow speed and long time consuming in traditional image reconstruction methods, a new method of multimedia image reconstruction based on virtual reality is proposed. Analysis of grid image data representation, multimedia image in virtual reality technology using wavelet decomposition, image encoding, visual point and image distance as a metric, threshold selection, image compression, image quality of differ- ent multimedia resources, according to the virtual reality scene measurement to classify the different resources, multi- media image reconstruction complete. The experimental results show that under the same condition and reconstruction of 50 images, the proposed method takes 150s, compared with the traditional method of time shortened 100s, the re- construction rate reached 70% on average, clarity is also greatly improved, it is concluded that the method of recon- struction of high quality, high speed, high resolution.
