acl.himpi.vpc_filter2d

C Prototype	*hi_s32 hi_mpi_vpc_filter2d(hi_vpc_chn chn, const hi_filter_2d_param filter_2d_param, hi_u32 task_id, hi_s32 milli_sec)*
Python Function	task_id, ret = acl.himpi.vpc_filter2d(chn, filter_2d_param, milli_sec)
Function Usage	Performs 2D convolutional filtering on the input image. 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. filter_2d_param: dict, 2D convolutional filtering information dictionary. For details, see hi_filter_2d_param. 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.
