一种用于高效多媒体IoT数据压缩的深度学习方案

A Deep Learning Scheme for Efficient Multimedia IoT Data Compression

Hassan N. Noura, Ola Salman, Raphaël Couturier

摘要:

考虑到多媒体感测数据的大量性质,多媒体物联网(MIoT)设备和网络将在功率和通信开销方面存在若干限制。应对大尺寸数据挑战的一种传统解决方案是使用有损压缩。然而,当前的有损压缩方案需要低压缩率来保证可接受的感知图像质量,这导致传送的数据大小的低减少,并且因此导致能量和带宽消耗的低减少。因此,需要有效的压缩解决方案来在数据大小(以及因此通信开销)和视觉降级之间取得良好的平衡。在本文中,深度学习(DL)超分辨率模型被应用于恢复高质量图像(在应用服务器端),作为具有高压缩比(在发送端)的输入退化图像。实验分析表明,该方法在提高压缩图像的视觉质量方面是有效的。因此,所提出的解决方案减少了有限MIoT设备的总体通信开销和功耗。

英文摘要:

Given the voluminous nature of the multimedia sensed data, the Multimedia Internet of Things (MIoT) devices and networks will present several limitations in terms of power and communication overhead. One traditional solution to cope with the large-size data challenge is to use lossy compression. However, current lossy compression schemes require low compression rate to guarantee acceptable perceived image quality, which results in a low reduction of the communicated data size and consequently a low reduction in the energy and bandwidth consumption. Thus, an efficient compression solution is required for striking a good balance between data size (and consequently communication overhead) and visual degradation. In this paper, a Deep-Learning (DL) super-resolution model is applied to recuperate high quality images (at the application server side) given as input degraded images with a high compression ratio (at the sender side). The experimental analysis shows the effectiveness of the proposed solution in enhancing the visual quality of the compressed and down-scaled images. Consequently, the proposed solution reduces the overall communication overhead and power consumption of limited MIoT devices.
