Hi all, I wonder if the following image manipulation operations are available to execute in the Myriad X "side": Image cropping Image resizing Image thresholding Image erosion Those operations would improve the effectiveness of the model Thank you

Hello jnebrera Image cropping: yes, using ImageManip node . Example here , which crops large frames into 2 smaller frames (tiling). Resizing: yes, using ImageManip node. Example here 720x720 to 300x300. Regarding thresholding/erosion, we don't support in the firmware, but you can develop your own CV algorithms that are run on the device. For erosion, there might be a Kornia function that does that already. I hope this helps! King regards, Erik

OAK image manipulation operations

Hi all,

I wonder if the following image manipulation operations are available to execute in the Myriad X "side":

Image cropping
Image resizing
Image thresholding
Image erosion

Those operations would improve the effectiveness of the model

Thank you

Hi Erik,

Thank you for the reply. We will take a look to kornia library

In my case, the main concern is we use an OAK-D-IoT-75 camera, thus the "host" is extremely limited, and all the functions have to run in the Myriad X VPU to make any sense

jnebrera That makes sense, so I would say either Kornia or custom CV model would be the way to go - as ESP32 doesn't have much processing power🙂
Thanks, Erik

Ok, thank you
