Macro Definition Documentation

AV_DETECTION_BBOX_LABEL_NAME_MAX_SIZE

#define AV_DETECTION_BBOX_LABEL_NAME_MAX_SIZE   64

Definition at line 36 of file detection_bbox.h.

AV_NUM_DETECTION_BBOX_CLASSIFY

#define AV_NUM_DETECTION_BBOX_CLASSIFY   4

At most 4 classifications based on the detected bounding box.

For example, we can get max 4 different attributes with 4 different DNN models on one bounding box. classify_count is zero if no classification.

av_detection_bbox_alloc()

AVDetectionBBoxHeader* av_detection_bbox_alloc	(	uint32_t	nb_bboxes,
		size_t *	out_size
	)

Allocates memory for AVDetectionBBoxHeader, plus an array of.

nb_bboxes 

AVDetectionBBox, and initializes the variables. Can be freed with a normal av_free() call.

Parameters

out_size

if non-NULL, the size in bytes of the resulting data array is written here.

av_detection_bbox_create_side_data()

AVDetectionBBoxHeader* av_detection_bbox_create_side_data	(	AVFrame *	frame,
		uint32_t	nb_bboxes
	)

Allocates memory for AVDetectionBBoxHeader, plus an array of.

nb_bboxes 

AVDetectionBBox, in the given AVFrame

frame 

as AVFrameSideData of type AV_FRAME_DATA_DETECTION_BBOXES and initializes the variables.
