How to use meanshift functionality from FastCV

fastcv_meanshift.cpp

#include "fastcv.h"
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
	// Image dimensions
	uint32_t srcWidth = 100;
	uint32_t srcHeight = 100;
	uint32_t srcStride = srcWidth;

	// OpenCV - Create source image
	Mat imageSrc = Mat( srcHeight, srcWidth, CV_8U);
	imageSrc.setTo(0);
	Rect r = Rect(40,40,50,50);
	imageSrc(r).setTo(255);

	// OpenCV - Display source image
	imshow( "Source Image", imageSrc );
	waitKey(0);

	// FastCV - Source data preparation
	const uint8_t *__restrict src = imageSrc.data;

	fcvRectangleInt window;
	window.x = window.y = 1;
	window.width = window.height = 50;

	fcvTermCriteria criteria;
	criteria.epsilon = 1;
	criteria.max_iter = 100;

	uint32_t output = 
	fcvMeanShiftu8	( src, srcWidth, srcHeight, srcStride, &window, criteria);

	cout << "Iterations : " << output << endl;
	cout << "Rect : " << window.x << "," << window.y << "," << window.width << "," << window.height << endl;

	return 0;
