hi_stitching_mean_param

Description

Converts the hi_stitching_gain_param.calulate_gain_callback.hist_config field into the hi_stitching_mean_param structure in the callback function used for gain compensation. For details, see Conversion Sample Code.

Prototype

typedef struct {
    hi_u32 pic_index;
    hi_u32 overlap_pic_index;
    hi_u32 mean_y_or_r;
    hi_u32 mean_u_or_g;
    hi_u32 mean_v_or_b;
    hi_u32 reserved[4];
} hi_stitching_mean_param;

Members

Member	Description
pic_index	Input image ID.
overlap_pic_index	When hi_stitching_histogram_type is set to OVERLAP_MEAN_VALUE, the overlap_pic_index parameter indicates the ID of the image that overlaps the input image.
mean_y_or_r	Average value of the Y or R component.
mean_u_or_g	Average value of the U or G component.
mean_v_or_b	Average value of the V or B component.
reserved	Reserved. To ensure compatibility in later versions, use the memset structure for resetting and initialization. Do not explicitly access the reserved field in the code.

Conversion Sample Code

hi_stitching_mean_param *hisData = (hi_stitching_mean_param *)hist_config;
