SSIMWave’s Video QoE Monitor
The backbone of SQM is the novel SSIMplus family of algorithms, co-invented by Dr. Zhou Wang, the primary inventor of SSIM and a Primetime Emmy winner, and his team after more than fifteen years of world-leading research.
SQM models behaviors of the human visual system to accurately predict video QoE. The solution provides straightforward predictions on what an average consumer would say about the quality of delivered video content on a scale of 0-100 and categorizes the quality as either bad, poor, fair, good, or excellent. The video QoE monitoring engine outperforms leading video quality assessment methods from Industry and Academia by a huge margin.
Our deep understanding of perceptual video quality assessment and human visual system enables us to design and develop accurate and fast video QoE measurement algorithms. SQM performs QoE of a 4k video at more than 100 fps on a GPU and a 1080p video at more than 60 fps on a multi-core processor.
The properties of a display device have a major impact on the perceived video QoE. SQM provides precise QoE predictions adapted to user devices.
Human visual system has the remarkable ability to adapt to varying luminance conditions. SQM has the unique capability to perform accurate HDR and standard dynamic range video QoE measurement.
SQM provides the exclusive ability to measure the impact of video properties such as resolution, dynamic range, and frame rate on perceived video QoE. As a result, the software provides accurate QoE of a test video with reference to the higher resolution, dynamic range, and frame rate source video.
SQM accomplishes a remarkable degree of accurate localization, deep to pixel level, and empowers its users to perform precise and in-depth evaluation, comparison, design, and optimization of their video acquisition, processing, compression, storage, reproduction, delivery, and display systems.
SQM has gone through numerous detailed testing, validation and comparison using in-house and publicly available subject-rated video quality assessment databases.
SQM is available with a user-friendly graphical user interface, for Windows, capable of performing batch jobs. SQM is also available as Windows and Linux SDKs and CLIs for real-time, accurate, and device-adaptive video QoE measurement. The libraries support both CPUs and GPUs depending on the availability of hardware
