title: Image in Image Algorithm
body: <p>I need an algorithm written in any language to find an image inside of an image, including at different scales. Does anyone know a starting point to solving a problem like this?</p>
  
  <p>For example:</p>
  
  <p>I have an image of 800x600 and in that image is a yellow ball measuring 180 pixels in circumference. I need to be able to find this image with a search pattern of a yellow ball having a circumference of 15 pixels. </p>
  
  <p>Thanks </p>
