hi_mpi_vpc_crop_resize

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

The Atlas Training Series Product does not support this API.

Description

Crops one or more ROIs from an image and resizes them to a specified size. This API is asynchronous.

Prototype

hi_s32 hi_mpi_vpc_crop_resize(hi_vpc_chn chn, const hi_vpc_pic_info *source_pic, hi_vpc_crop_resize_region crop_resize_info[], hi_u32 count, hi_u32 *task_id, hi_s32 milli_sec)

Parameters

Parameter

Input/Output

Description

chn

Input

Channel ID for image processing.

source_pic

Input

Pointer to the source image information.

crop_resize_info

Input

Image cropping and resizing information array. The array length is the same as that of the count value.

count

Input

Number of crop and resize ROIs. Must be in the range of [1, 256].

task_id

Output

Pointer to the task ID, used to identify a task.

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.
