Re: Fast pixel transfer to and from graphic cards in OpenVG ?
Thank you for your reply !
Right. If I work on a single image, step iv will not be used.

Doing all these procedures on ARM-only platform cannot achieve our target frame rate. That's why I approached to GPU.
The image sequences(size 512x512) are typically more than 10 minutes, so it would not be possible to load all of them to GPU side at the initial stage.
Yes, I will try this sampling mode and compare the speed and quality.
