Member Function Documentation

void cv::gpu::FAST_GPU::operator()	(	const GpuMat &	image,
		const GpuMat &	mask,
		GpuMat &	keypoints
	)

finds the keypoints using FAST detector supports only CV_8UC1 images

		const GpuMat &	mask,
		std::vector< KeyPoint > &	keypoints
	)

void cv::gpu::FAST_GPU::downloadKeypoints	(	const GpuMat &	d_keypoints,
		std::vector< KeyPoint > &	keypoints
	)

download keypoints from device to host memory

void cv::gpu::FAST_GPU::convertKeypoints	(	const Mat &	h_keypoints,
		std::vector< KeyPoint > &	keypoints
	)

convert keypoints to KeyPoint vector

void cv::gpu::FAST_GPU::release

(

)

release temporary buffer's memory

int cv::gpu::FAST_GPU::calcKeyPointsLocation	(	const GpuMat &	image,
		const GpuMat &	mask
	)

find keypoints and compute it's response if nonmaxSupression is true return count of detected keypoints

int cv::gpu::FAST_GPU::getKeyPoints

(

GpuMat &

keypoints

)

get final array of keypoints performs nonmax supression if needed return final count of keypoints
