about real-time edge detection

[Danee-wawawa]

Hello, thank you very much for your summary and sharing.
Is there any recommendation for an open source algorithm for real-time edge detection during video shooting?
Looking forward for your answer.

Depending on your computing devices.

If you deploy edge detectors on GPU, even 3 or 4 years ago released cards like Nvidia 1060, 1070 can do the job in real-time, The SOTA methods (HED, RCF, LPCB) would run real fast. HED and RCF operate faster because they have lighter decoders.

If you tend to deploy models on edge devices, you need to replace the backbones of the above methods with lightweight ones and develop effective and efficient decoders.

Ok, thank you for these suggestions.
