title: How to add effects to image
body: <p>I am new to the image processing.I want to know that how i can add the effects to the image using EmguCV or any other technique.Just like Microsoft LifeCam.(ex. showing hat on the head,showing name on the head etc.)</p>
  
  <p>Please help,thanks in advance.</p>
  
  <p><strong>Update</strong>::I am now working with the code </p>
  
  <blockquote>
    <p>face recognition x86</p>
  </blockquote>
  
  <p>in that i am using the function currentFrame.Draw(...) to drow the image.
  now i want to add the new bitmap image with the current image but it showing me the exception.</p>
  
  <pre><code>OpenCV: The operation is neither 'array op array' (where arrays have the same size and the same number of channels), nor 'array op scalar', nor 'scalar op array'
  </code></pre>
  
  <p>So anything which i will do with the Image myimg.Add()</p>
