FasterRcnn训练数据集参数配置

<div class="blogpost-body" id="cnblogs_post_body">
<p>说明：本博文假设你已经做好了自己的数据集，该数据集格式和VOC2007相同。做好数据集后，我们开始训练，下面是训练前的一些修改。<br>本文来自：http://www.lai18.com/content/2526443.html</p>
<h2> </h2>
<h2><strong>1 、VOCdevkit2007\VOCcode\VOCinit.m的修改</strong></h2>
<h3><strong>（1）路径的修改</strong></h3>
<div class="dp-highlighter bg_plain">

<strong>[plain]</strong>
<a class="ViewSource" href="http://www.lai18.com/content/2526443.html#" title="view plain">view plain</a>
<a class="CopyToClipboard" href="http://www.lai18.com/content/2526443.html#" title="copy">copy</a>
<div>

</div>
</div>
  </div>
  <ol start="1"><li class="alt">VOCopts.annopath=[VOCopts.datadir VOCopts.dataset '/Annotations/%s.xml'];  </li><li>VOCopts.imgpath=[VOCopts.datadir VOCopts.dataset '/JPEGImages/%s.jpg'];  </li><li class="alt">VOCopts.imgsetpath=[VOCopts.datadir VOCopts.dataset '/ImageSets/Main/%s.txt'];  </li><li>VOCopts.clsimgsetpath=[VOCopts.datadir VOCopts.dataset '/ImageSets/Main/%s_%s.txt'];  </li><li class="alt">VOCopts.clsrespath=[VOCopts.resdir 'Main/%s_cls_' VOCopts.testset '_%s.txt'];  </li><li>VOCopts.detrespath=[VOCopts.resdir 'Main/%s_det_' VOCopts.testset '_%s.txt'];  </li></ol>
</div>
<p> <br>上面这些路径要正确，第一个是xml标签路径；第二个是图片的路径；第三个是放train.txt、val.txt、test.txt和trainval.txt的路径；第四、五、六个不需要；一般来说这些路径不用修改，你做的数据集格式和VOC2007相同就行。</p>
<h3><strong>（2）训练集文件夹修改</strong></h3>

<a class="CopyToClipboard" href="http://www.lai18.com/content/2526443.html#" title="copy">copy</a>
<div>

</div>
</div>
  </div>
  <ol start="1"><li class="alt">VOCopts.dataset = '你的文件夹名';  </li></ol>
</div>
<p> <br><br>然后将VOC2007路径注释掉，上面“你的文件夹名”是你放Annotations、ImageSets、JPEGImages文件夹的文件夹名。</p>
<h3><strong>（3）标签的修改</strong></h3>
<div class="dp-highlighter bg_plain">

<strong>[plain]</strong>
<a class="ViewSource" href="http://www.lai18.com/content/2526443.html#" title="view plain">view plain</a>
<a class="CopyToClipboard" href="http://www.lai18.com/content/2526443.html#" title="copy">copy</a>
<div>

</div>
</div>
  </div>
  <ol start="1"><li class="alt">VOCopts.classes={...  </li><li> '你的标签1'  </li><li class="alt"> '你的标签2'  </li><li> '你的标签3'  </li><li class="alt"> '你的标签4'};  </li></ol>
</div>
<p> 将其改为你的标签。<br><br></p>
<h2>2 、VOCdevkit2007\results</h2>
<p> results下需要新建一个文件夹，名字和xml中的<folder>***</folder>对应。***文件夹下新建一个Main文件夹。</p>
<h2><strong>3 、VOCdevkit2007\local</strong></h2>
<p> local下需要新建一个文件夹，名字和xml中的<folder>***</folder>对应。<br><br></p>
<h2><strong>4 、function\fast_rcnn\fast_rcnn_train.m</strong></h2>
<div class="dp-highlighter bg_plain">
  <div class="bar">
<div class="tools">
<strong>[plain]</strong>
<a class="ViewSource" href="http://www.lai18.com/content/2526443.html#" title="view plain">view plain</a>
<a class="CopyToClipboard" href="http://www.lai18.com/content/2526443.html#" title="copy">copy</a>
<div>

</div>
</div>
  </div>
  <ol start="1"><li class="alt">ip.addParamValue('val_iters',    500,          @isscalar); </li><li>ip.addParamValue('val_interval', 2000,          @isscalar);  </li></ol>
</div>
<p> <br>可能在randperm(N,k)出现错误，可以将500改小点，比如200.<br><br></p>
<h2><strong>5、function\rpn\proposal_train.m</strong></h2>
<p> 这里的问题和fast_rcnn_train.m一样。</p>
<h2><strong>6.imdb\imdb_eval_voc.m</strong></h2>

</div>
<p> 注释掉</p>
