hi_mpi_vpc_lut_remap

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Remaps an image based on the input pixel position remapping LUT. This API is asynchronous.

hi_s32 hi_mpi_vpc_lut_remap(hi_vpc_chn chn, hi_warp_transform_param *transform_param, hi_remap_lut *remap_lut, hi_u32 *task_id, hi_s32 milli_sec)

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing.
transform_param	Input	Remapping parameter.
remap_lut	Input	Information about the pixel position remapping LUT. Call hi_mpi_vpc_get_affine_lut, hi_mpi_vpc_get_perspective_lut, or hi_mpi_vpc_get_remap_lut to obtain the pixel position remapping LUT in advance. However, the resizing algorithm of this API must be the same as that of the get API. Otherwise, the remapping result may not meet the expectation.
milli_sec	Input	Timeout interval (ms). -1: blocking mode. 0: non-blocking mode. > 0: timeout interval (timeout mode). The timeout interval varies with the operating system. The deviation is generally within a time slice of an operating system. For example, if the time slice of an operating system is 4 ms and the value of milli_sec is set to 1, the actual timeout interval ranges from 1 ms to 5 ms. When the CPU load is high, the timeout interval may fluctuate.
task_id	Output	Pointer to the task ID, which is used to identify a task.
