Functions
cv::Rect	jsk_recognition_utils::boundingRectOfMaskImage (const cv::Mat &image)
	compute bounding rectangle of mask image.
bool	jsk_recognition_utils::compareHistogramWithRangeBin (const jsk_recognition_msgs::HistogramWithRangeBin &left, const jsk_recognition_msgs::HistogramWithRangeBin &right)
	return true if left.count is larger than right.count.
cv::MatND	jsk_recognition_utils::computeHistogram (const cv::Mat &input_image, int bin_size, float min_value, float max_value, const cv::Mat &mask_image)
	simple wrapper for cv::calcHist.
std::vector < jsk_recognition_msgs::HistogramWithRangeBin >	jsk_recognition_utils::cvMatNDToHistogramWithRangeBinArray (const cv::MatND &cv_hist, float min_value, float max_value)
	convert cv::MatND to jsk_recognition_msgs::HistogramimageWithRangeBin array

	draw bin to cv::Mat
cv::MatND	jsk_recognition_utils::HistogramWithRangeBinArrayTocvMatND (const std::vector< jsk_recognition_msgs::HistogramWithRangeBin > &histogram)
	convert jsk_recognition_msgs::HistogramimageWithRangeBin array to cv::MatND
bool	jsk_recognition_utils::isBGR (const std::string &encoding)

bool	jsk_recognition_utils::isRGB (const std::string &encoding)
bool	jsk_recognition_utils::isRGBA (const std::string &encoding)
void	jsk_recognition_utils::labelToRGB (const cv::Mat src, cv::Mat &dst)
	convert label image to rgb one.
void	jsk_recognition_utils::sortHistogramWithRangeBinArray (std::vector< jsk_recognition_msgs::HistogramWithRangeBin > &bins)
	sort std::vector<jsk_recognition_msgs::HistogramWithRangeBin>. largest value will be at the first element.
