hi_s32 hi_mpi_vpc_median_blur(hi_vpc_chn chn, const hi_median_blur_param* median_blur_param, hi_u32 *task_id, hi_s32 milli_sec)

Python Function

task_id, ret = acl.himpi.vpc_median_blur(chn, median_blur_param, milli_sec)

Parameters

Parameter	Description
chn	Int, channel ID for image processing. For the Atlas 350 accelerator card, the value range is [0, 256). The maximum number of channels is 256.
median_blur_param	Dict, median filtering information dictionary. For details, see hi_median_blur_param.
milli_sec	Int, timeout interval, in milliseconds.

Parameter

Description

chn

Int, channel ID for image processing.

For the Atlas 350 accelerator card, the value range is [0, 256). The maximum number of channels is 256.

median_blur_param

Dict, median filtering information dictionary. For details, see hi_median_blur_param.

milli_sec

Int, timeout interval, in milliseconds.

Return Value

Return Value	Description
task_id	Int, task ID, used to identify a task.
ret	Int, error code. 0 indicates success. Other values indicate failure. For details, see VPC Return Codes.

Restrictions

The resolution of the input and output images ranges from 10 x 6 to 4096 x 8192. The resolution of the input image is the same as that of the output image.

The following input image formats are supported (the output image format is the same as the input image format):

HI_PIXEL_FORMAT_YUV_400 = 0,               // YUV400 8bit
HI_PIXEL_FORMAT_YUV_SEMIPLANAR_420 = 1,    // YUV420SP NV12 8bit   
HI_PIXEL_FORMAT_YVU_SEMIPLANAR_420 = 2,    // YUV420SP NV21 8bit 
HI_PIXEL_FORMAT_YUV_SEMIPLANAR_422 = 3,    // YUV422SP 8bit
HI_PIXEL_FORMAT_YVU_SEMIPLANAR_422 = 4,    // YVU422SP 8bit
HI_PIXEL_FORMAT_YUYV_PACKED_422 = 7,       // YUV422Packed YUYV 8bit
HI_PIXEL_FORMAT_YVYU_PACKED_422 = 9,       // YUV422Packed YVYU 8bit
HI_PIXEL_FORMAT_YUV_PACKED_444 = 11,      // YUV444 Package  8bit
HI_PIXEL_FORMAT_RGB_888 = 12,             // RGB888
HI_PIXEL_FORMAT_BGR_888 = 13,             // BGR888
HI_PIXEL_FORMAT_YVU_PACKED_444 = 58,       // YVU444 Package 8bit
HI_PIXEL_FORMAT_RGB_888_PLANAR = 69,       // RGB888 Planar
HI_PIXEL_FORMAT_BGR_888_PLANAR = 70,       // BGR888 Planar
