I&amp;#x27;m casually familiar with Video Amplification (the approach at SIGGRAPH a decade ago IIRC), but have never implemented it myself.  A really cool result, using the changes in the phase of the basis vectors over time to infer motion, without having to do dense optic flow.&lt;p&gt;I&amp;#x27;m curious how you would combine acoustic localization in 3 space with motion amplification.  I unreservedly agree that they are both &amp;quot;super cool&amp;quot;, but don&amp;#x27;t see how they tie together to make something greater than the sum of their parts.&lt;p&gt;The only thing I thought of is, if two data channels (video, audio) are registered accurately enough, one could maybe combine the spatially limited frequency information from both channels for higher accuracy?&lt;p&gt;For example:  voxel 10,10,10 is determined (by the audio system) to have a high amount of coherent sound with a fundamental frequency of 2khz.   Can that 2khz + 10,10,10 be passed to the video system to do something.... cool?  useful?   If we know that sound of a certain spectral profile is coming from a specific region, is it useful to amplify (or deaden) video motion with a same frequency?</text><parent_chain><item><author>davidb_</author><text>Combining this with Motion Amplification&amp;#x2F;Video Magnification [1] could result in some very interesting visuals and applications for factory equipment.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=rEoc0YoALt0&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.youtube.com&amp;#x2F;watch?v=rEoc0YoALt0&lt;/a&gt; Explainer Youtube video about Motion Amplification</text></item></parent_chain></comment><story><title>DIY Acoustic Camera</title><url>https://navat.substack.com/p/diy-acoustic-camera-using-uma-16</url></story>
