acl.himpi.vpc_lut_remap

C Prototype	*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)**
Python Function	task_id, ret = acl.himpi.vpc_lut_remap(chn, transform_param, remap_lut, milli_sec)
Function Usage	Remaps an image based on the input pixel position remapping LUT. This API is asynchronous. The Atlas 200/300/500 Inference Product does not support this API. The Atlas Training Series Product does not support this API.
Input Description	chn: int, image processing channel ID. transform_param: dict, remapping transformation parameter dictionary. For details, see hi_warp_transform_param. remap_lut: information about the pixel position remapping LUT. For details, see hi_remap_lut. Call acl.himpi.vpc_get_affine_lut, acl.himpi.vpc_get_perspective_lut, or acl.himpi.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: int, 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.
Return Value	ret: int, error code. 0 indicates success. Other values: failure. For details, see VPC Return Codes. task_id: task ID, used to identify a task.
