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
