问题
I'm trying to load an OpenCV image (IplImage) into GPU with clCreateImage2D.
Reason of using IplImage is, i want to load any kind of image.(jpg, bmp, png).
I can load image using clCreateImage2D with CL_MEM_READ_ONLY | CL_MEM_COPY_HOST_PTR mem_flags, and CL_RGB and CL_UNORM_SHORT_565 type. But in kernel function read_imagef function is not accept CL_UNORM_SHORT_565 type.
So, how can i send RGB image to OpenCL kernel function?
Edit: I converted the input image to 32bit. Bu tnow what would be the image_channel_order and image_channel_data_type? Order can't be RGBA because it has no alpha channel.
回答1:
24 bit RGB is not supported by OpenCL. So you have to first convert it to 32 bit RGB and then pass it to the OpenCL kernel
