Already I had answered in your previous question, asked for measurement of the ankle (L and W), which also required to localized the most distance markers

As the color of ROIs is quite clear, you can try to get a range of red pixels with different color models. Please note, the definition of colors is quite subjective, there may be a possibility of representing the same color in different ways. Some cases what you have seen may not be same for a computer or vice versa.
Here one ways, modify as requirements (Different Color Models and Pixel Values in dominant plane)
rgbImage=imread('image_preeti.jpeg');
ycbrImage=rgb2ycbcr(rgbImage);
[r,c]=find(ycbrImage(:,:,3)>180);
%......
rgbImage(r,c,1:3)=255;
imshow(rgbImage);
