<p>Before starting any coding, I wanted to set up my remote git repositories. I had already decided I wanted the project mirrored over two remote git repositories from different providers as a safety precaution. My intial plan was to use the university’s GitLab instance but as it’s recently been moved behind the firewall it would have made mirroring quite difficult. Instead, I decided to use my personal
|
|
<a href="https://git.oscar.blue">Gitea instance</a> and mirror it to my personal account on the official
|
|
<a href="https://gitlab.com/oscarpocock">GitLab instance</a>.</p>
|
|
<p>
|
|
<a href="https://git.oscar.blue/noble/mmp-osp1">Gitea</a> →
|
|
<a href="https://gitlab.com/oscarpocock/mmp-osp1">GitLab</a></p>
|
|
<p>Gitea will periodically push to GitLab.</p>

<p>Towards the end of the week I put together some simple code to reduce the frame set. I used the OpenCV Python module to export the frames of a given video to an <code>output/</code> folder. The path of this folder is also stored in the <code>outputfolder</code> variable we see used on line 7.</p>
|
|
<p>Although this code is a first step at reducing the frames set - it doesn’t give us much feedback about the frames that have been deleted or kept.</p>
