Performance

The heaviest stage of the algorithm is the Video Undistortion. The following metrics come as a result of measuring this stage.

Overall Latency

The RidgeRun Real-Time Video Stabilizer has a latency of the processing time of one single frame, it is important to consider that this is the stabilizer process latency, you need to consider possible additional latency added by: video dequeue, pipelines queues, encoding/decoding process, streaming or another process required by your project.

Qualcomm RB5

This is using a synthetic image running at average conditions on Ubuntu 20.04 during 100 iterations.

Backend Dimensions Processing Time (ms) Average Framerate (fps)
OpenCV 720p 22.28 44.88
1080p 171.6 5.83
4K 781.7 1.28
OpenCL 720p 11.00 91.00
1080p 18.69 53.5
4K 41.65 24.01

It used the concept example for performance measurement. The CPU load should be similar to the Xavier NX, consuming up to 2-3 cores.

NVIDIA Jetson

Xavier NX

This is using a synthetic image running at average conditions on Jetpack 5.1.2 during 100 iterations. It uses the maximum performance power profile and jetson clocks. The capture element is the NvArgusCameraSrc at 30 fps (the estimated fps are derived from the processing time from GstShark). The CPU load is the percentage of a single core usage using perf and the GPU load using tegra stats.

NXP i.MX8 MP

This uses a synthetic image running at average conditions on Yocto Hardnott during 100 iterations. Please, note that the imx8mp is one of the most basic boards.

Backend Dimensions Processing Time (ms) Average Framerate (fps)
OpenCV 720p 84.42 11.85

X86 PC

This uses a synthetic image running at average conditions on Ubuntu 18.04 during 100 iterations.
