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);

Parameter	Input/Output	Description
chn	Input	Channel ID for image processing.
filter_2d_param	Input	2D convolutional filtering information. The input and output image information and convolutional filtering parameters are configured in the hi_filter_2d_param structure.
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.
