It's an application of &quot;eigenimages&quot; that use principal component analysis to pictures of human faces. In the process it generates an image that is an &quot;average&quot; image when each image of the set contributes the same amount to the final image. That can be used to recognize faces or morph faces.<br />The quality depends solely on the image set. The more faces are not aligned the &quot;blurrier&quot; it is and the more nightmarish it becomes.<br /><a href="https://upload.wikimedia.org/wikipedia/commons/6/67/Eigenfaces.png" title="https://upload.wikimedia.org/wikipedia/commons/6/67/Eigenfaces.png" class="attachment" id="attachment-874312" rel="nofollow external">https://upload.wikimedia.org/wikipedia/commons/6/67/Eigenfaces.png</a>
