19 <meta name="Description" content="ImageMagick® is a software suite to create, edit, and compose bitmap images. It can read, convert and write images in a variety of formats (about 100) including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves. ImageMagick is free software delivered as a ready-to-run binary distribution or as source code that you can freely use, copy, modify, and distribute. Its license is compatible with the GPL. It runs on all major operating systems. The functionality of ImageMagick is typically utilized from the command line or you can use the features from programs written in your favorite programming language. Choose from these interfaces: MagickCore (C), MagickWand (C), ChMagick (Ch), Magick++ (C++), JMagick (Java), L-Magick (Lisp), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface, use ImageMagick to modify or create images automagically and dynamically."/>

167<p>Use the <kbd>compare</kbd> program to mathematically and visually annotate the difference between an image and its reconstruction. See <a href="../www/command-line-processing.html">Command Line Processing</a> for advice on how to structure your <kbd>compare</kbd> command or see below for example usages of the command.</p>
168
169<div style="margin: auto;">
170 <h2><a name="usage"></a>Example Usage</h2>
171</div>
172
173<p>We list a few examples of the <kbd>compare</kbd> command here to illustrate its usefulness and ease of use. To get started, lets compare an image to one thats been sharpened:</p>
174
175<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>convert rose.jpg -sharpen 0x1 reconstruct.jpg</span><span class='crtout'></span><span class="crtprompt"> $magick&gt; </span><span class='crtin'>compare rose.jpg reconstruct.jpg difference.png</span><span class='crtout'></span><span class="crtprompt"> $magick&gt; </span><span class='crtin'>compare -compose src rose.jpg reconstruct.jpg difference.png</span></p>
176<div class="image">
177<p>
178 <a href="../images/rose.jpg"><img src="../images/rose.jpg" width="70" height="46" alt="rose" /></a>
179 <a href="../images/reconstruct.jpg"><img src="../images/reconstruct.jpg" width="70" height="46" alt="rose" /></a>
180 <img style="margin:13px 0;" src="../images/right.gif" width="20" height="20" alt="==>" />
181 <a href="../images/difference.png"><img src="../images/difference.png" width="70" height="46" alt="rose" /></a>
182</p>
183</div>
184
185<p>The red areas of the difference image emphasizes (highlight) pixels that are affected by the image sharpening, whereas white de-emphasizes (lowlight) pixels that are untouched by the sharpening process.</p>
186
187<p>In addition to the visual interpretation of the difference in an image and its reconstruction, we report a mathematical measure of the difference:</p>
188
189<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>compare -verbose -metric mae rose.jpg reconstruct.jpg difference.png</span><span class='crtout'>Image: rose.jpg <br/>
190 Channel distortion: MAE <br/>
191 red: 2282.91 (0.034835) <br/>
192 green: 1853.99 (0.0282901) <br/>
193 blue: 2008.67 (0.0306503) <br/>
194 all: 1536.39 (0.0234439) <br/></span></p><p>Or, if you just want the red channel distortion, use this command:</p>
195
196<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>compare -channel red -metric PSNR rose.jpg reconstruct.jpg difference.png</span><span class='crtout'>19.63</span></p>
197<p>Or, if you just want the overall image distortion, use this command:</p>
198
199<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>compare -metric PSNR rose.jpg reconstruct.jpg difference.png</span><span class='crtout'>28.31</span></p>
200<p>If the reconstructed image is a subimage of the image, the compare program returns the best match offset. In addition, it returns a similarity image such that an exact match location is completely white and if none of the pixels match, black, otherwise some gray level in-between:</p>
201
202<p class='crt'><span class="crtprompt"> $magick&gt; </span><span class='crtin'>compare -metric RMSE logo.png wizard.jpg similarity.gif</span><span class='crtout'>85.05 (0.00129778) @ 353,157</span></p>
203<p>You can find additional examples of using <kbd>compare</kbd> in <a href="http://www-106.ibm.com/developerworks/library/l-graf/?ca=dnt-428">Graphics from the Command Line</a>. Further discussion is available in <a href="http://www-106.ibm.com/developerworks/library/l-graf2/?ca=dgr-lnxw15GraphicsLine">More Graphics from the Command Line</a> and <a href="http://www.imagemagick.org/Usage/">Examples of ImageMagick Usage</a>.</p>
