I am going to implement the laplace pyramid with VPI,this will base on the guassian pyramid ,how to do image add/substract operation on vpi image class?
Thanks

Hi,

We don’t support pixel-wise operation currently.
If you create the VPI image with a pre-allocated buffer, you can apply the addition on the buffer directly.

Thanks.

the addition operation will be executed on GPU or CPU?
The pipeline for my project ,I 've tried my best to do the heavy compution on device,if the addition operation switched to CPU,it will pull the all pipeline performance
And the addition operation is a very basic and nessary operation in CV field(like in opencv),could you please support it ?
Thanks.

Hi,

Use GPU will have a better performance if you implement it in parallel.

However, you can try the unified memory if you prefer a CPU implementation.
It can save non-wanted memory copy.

Thanks.
