Hi Pramod, Anshu,
Thank you very much for supporting on ORB performance estimation.
You provided below.
ORB features computation :
- Descriptor preparation @30fps : 389 [Mcycles]
- Matching @30fps : 60 [Mcycles]
- Total @30fps : 450 [Mcycles]
Input pixels assumed: 131997 pixels (for 4 image regions of resolution 256x540 + 4 image regions of 197x415).
Matching of 512 descriptors list with another 512 descriptor list where each descriptor is 256 bit wide
On above estimation, input image format is assumed as YUV420 ?
(256x540x4 + 197x415x4 x1.5=1319970)
Best regards,
Saito
