C++ (Cpp) Descriptor::getDescriptorVector Examples

Example #1

File: Metric.cpp Project: rodschulz/CC5204_T2

double Metric::ManhattanMetric(const Descriptor &_desc1, const Descriptor &_desc2)
{
	vector<double> d1 = _desc1.getDescriptorVector();
	vector<double> d2 = _desc2.getDescriptorVector();

	double result = 0;
	size_t length = d1.size();
	for (size_t i = 0; i < length; i++)
	{
		result += fabs(d1[i] - d2[i]);
	}

	return result;
}

Example #2

File: Metric.cpp Project: rodschulz/CC5204_T2

double Metric::MaxMetric(const Descriptor &_desc1, const Descriptor &_desc2)
{
	vector<double> d1 = _desc1.getDescriptorVector();
	vector<double> d2 = _desc2.getDescriptorVector();

	double result = 0;
	size_t length = d1.size();
	for (size_t i = 0; i < length; i++)
	{
		double delta = fabs(d1[i] - d2[i]);
		if (result < delta)
			result = delta;
	}

	return result;
}

Example #3

{
	vector<double> d1 = _desc1.getDescriptorVector();
	vector<double> d2 = _desc2.getDescriptorVector();

	double result = 0;
	size_t length = d1.size();
	for (size_t i = 0; i < length; i++)
	{
		double a = d1[i];
		double b = d2[i];
		result += ((a - b) * (a - b));
	}
