<h1>vatic.js A pure Javascript video annotation tool</h1>
<ol>
<li>
<p>This tool can be used to easily annotate a video, without having to install anything.</p>
<p>Optical flow is used to track your annotations, so that have to do as little work as possible ;-)</p>
<p>This tool works best in Chrome, and has also been successfully tested in Firefox.</p>
</li>
<li>
<p>To start a new video annotation, select a video file: <input type="file" id="videoFile" accept="video/*" /></p>
<p>To resume a previous annotation, select a frames zip archive: <input type="file" id="zipFile" accept=".zip" /></p>
<p>Note: Keep the focus on the browser during the entire extraction process, or frames might be skipped.</p>
<p class="output" id="videoDimensions"></p>
<p class="output" id="extractionProgress"></p>
</li>
<li>
<p>Download the extracted frames zip archive: <input type="button" id="downloadFrames" value="Get frames zip archive" disabled="disabled" /></p>
</li>
<li>
<p>Optional: Load an existing <a href="http://web.mit.edu/vondrick/vatic/" target="new">vatic</a>-compatible XML annotation file: <input type="file" id="xmlFile" accept=".xml" disabled="true" /></p>
<p>This is useful for example if:</p>
<ul>
<li>You are resuming a previous annotation.</li>
<li>You already have a first version of your automatic object detector, which you want to improve by manually correcting its errors.</li>
</ul>
<p>Note: Launch your object detector on the extracted frames rather than on the original video to avoid frame/annotation mismatches!</p>
</li>
<li>
<p>Manually annotate the frame sequence:</p>
<p>To create a new bounding box, first click 'n' (for new), and then left click on two locations in the video corresponding to the corners of the box.</p>
<p>Tip: Use the spacebar to play/pause the video, and the left and right arrows to navigate frame by frame.</p>
<p>Tip: The visibility of each object can be toogled with its visiblity checkbox under the video.</p>
<p>Tip: Zoom in with your browser to place the bounding boxes more accurately.</p>
