Opencv facedetect lena.jpg on IMX6Q : detection time = 2506.65 ms

[hjpark71]

Hi NXP,

I run Opencv "samples/c/facedetect lena.jpg" on Linaro-alip what is running on imx6q 800MHz.

it works well but the speed is so slow..

it is message from facedetect..

detection time = 2506.65 ms

do you think  2506.65 ms is normal on imx6q ?

or, Is there any way to improve the speed of opencv on imx6q?

Thanks and Best regards,

HJ

Hi hj

2506ms for Facedetection is too much!, Please make sure that you are y using Opencv on ubuntu hardfloat rootfs.
