Detailed Description

Preprocessor object for YOLOv8 serials model.

Member Function Documentation

bool fastdeploy::vision::detection::YOLOv8Preprocessor::Run	(	std::vector< FDMat > *	images,
		std::vector< FDTensor > *	outputs,
		std::vector< std::map< std::string, std::array< float, 2 >>> *	ims_info
	)

Process the input image and prepare input tensors for runtime.

Parameters

[in]	images	The input image data list, all the elements are returned by cv::imread()
[in]	outputs	The output tensors which will feed in runtime
[in]	ims_info	The shape info list, record input_shape and output_shape

void fastdeploy::vision::detection::YOLOv8Preprocessor::SetMiniPad ( bool is_mini_pad )

inline

Set is_mini_pad, pad to the minimum rectange which height and width is times of stride

void fastdeploy::vision::detection::YOLOv8Preprocessor::SetScaleUp ( bool is_scale_up )

inline

Set is_scale_up, if is_scale_up is false, the input image only can be zoom out, the maximum resize scale cannot exceed 1.0, default true
