Difference between vxAddUseKernel() and vxAddDeviceKernelIntel()

[Deepak_C_R]

What is the difference between vxAddUseKernel() and vxAddDeviceKernelIntel() ?.

The generated code using VAD contains vxAddUseKernel() function to add user kernel function but in the cnn_custom_kernel sample code the function used is vxAddDeviceKernelIntel() for doing the same.

Is the cnn_custom_kernel codes are generated using VAD tool ?.

Hi Deepak, 

 vxAddDeviceKernelIntel adds a device kernel - gpu opencl kernel. This is an ability Intel offers in CV SDK. 
so, vxAddUserKernel is a regular cpu user kernel, while the vxAddDeviceKernelIntel  is an openCL gpu kernel.
vad will also enable to create openCL gpe kernels in the upcoming release.

You can also use the samples user guide that explains these functions.

Stav
