[Hasa]

I have posted this question long time ago but no reaction is seen so far, if you have any idea about it, I will appreciate your response:

Convert (or copy) cuda simple array to VPIImage

I have checked all the sample codes of VPI and in all of them, the image is read using opencv, converted to grayscale and then wrapped by a VPI array. However, for my application, I have my images as Cuda allocated “unsigned char*” on the device memory (no opencv, no cpu array) and they are color images, so my question is how should I transfer the data from my gpu array to VPIImage? Here is the code I am seeking: unsigned char * inp_img; cudaMalloc((void**)&inp_img, array_size* sizeof(unsigned…
