<p>Extracts a subset of points from a point cloud based on specified indices. </p>
<p>This function filters the input point cloud by extracting the points corresponding to the provided set of indices. The <code>negative</code> parameter determines whether to extract the points listed in the indices (if <code>negative</code> is false) or to exclude the points listed in the indices (if <code>negative</code> is true).</p>
<p>The function uses PCL's <code>ExtractIndices</code> to perform the extraction and returns the resulting set of indices as a shared pointer to a vector of integers.</p>

<dl class="section note"><dt>Note</dt><dd>This function uses PCL's <code>ExtractIndices</code> filter to extract or remove the points based on the provided indices. </dd>
