Problem with HSV

Need some help, i am not able to find the desired contour

Input: image description

After applying binary filter: image description

After applying HSV filter: image description

Output: image description

However, the desired output should have been: image description

Need some help, this is my code for hsv:

include "opencv2/core/core.hpp"

include "opencv2/highgui/highgui.hpp"

include "opencv2/imgproc/imgproc.hpp"

include "iostream"

using namespace cv; using namespace std;

int main() {

Mat image;
image = imread("C:/Proj/Denoised.jpg", CV_LOAD_IMAGE_COLOR);

if (!image.data)
{
    cout << "Could not open the denoised image" << std::endl;
    return -1;
}

// Create a new matrix to hold the hsv image
Mat HSV;

// convert RGB image to hsv image
cvtColor(image, HSV, CV_BGR2HSV);

namedWindow("Display RGB image", CV_WINDOW_AUTOSIZE);
imshow("Display RGB image", image);

//DISPLAY image
namedWindow("Result : HSV image", CV_WINDOW_AUTOSIZE);
imshow("Result : HSV image", HSV);

//save the HSV image
imwrite("C:/Proj/HSVimage.jpg", HSV);

waitKey(0);
