Constructor & Destructor Documentation

descriptorExtractor()

cv::cnn_3dobj::descriptorExtractor::descriptorExtractor	(	const String &	device_type,
		int	device_id = 0
	)

Set the device for feature extraction, if the GPU is used, there should be a device_id.

Parameters

device_type	CPU or GPU.
device_id	ID of GPU.

Member Function Documentation

extract()

void cv::cnn_3dobj::descriptorExtractor::extract	(	InputArrayOfArrays	inputimg,
		OutputArray	feature,
		String	feature_blob
	)

Extract features from a single image or from a vector of images. If loadNet was not called before, this method invocation will fail.

Parameters

inputimg	Input images.
feature	Output features.
feature_blob	Layer which the feature is extracted from.

getDeviceId()

int cv::cnn_3dobj::descriptorExtractor::getDeviceId

(

)

Get device ID information for feature extraction.

getDeviceType()

String cv::cnn_3dobj::descriptorExtractor::getDeviceType

(

)

Get device type information for feature extraction.

loadNet()

void cv::cnn_3dobj::descriptorExtractor::loadNet	(	const String &	model_file,
		const String &	trained_file,
		const String &	mean_file = ""
	)

Initiate a classification structure, the net work parameter is stored in model_file, the network structure is stored in trained_file, you can decide whether to use mean images or not.

Parameters

model_file	Path of caffemodel which including all parameters in CNN.
trained_file	Path of prototxt which defining the structure of CNN.
mean_file	Path of mean file(option).

setDeviceId()

void cv::cnn_3dobj::descriptorExtractor::setDeviceId

(

const int &

device_id

)

Set device ID information for feature extraction. Useful to change device without the need to reload the net. Only used for GPU.
