<div>Hi all!,</div>
<div> </div>
<div>what is the generic motion detector you are using Mathieu? I use pdp...</div>
<div> </div>
<div>Best Regards</div>

<div>> Nevertheless, if I have a picture of size (240 320 3), I can make groups of</div>
<div>> rows and columns, for example I [#redim (15 16 20 16 3)], which turns a</div>
<div>> picture into a 5-dimensional grid, and then if I [#transpose 1 2], I will</div>
<div>> have a 5-dimensional grid that is a 2-dimensional grid of 16x16 icons. After</div>
<div>> that, many effects and analyses that GF can do on pictures will also work on</div>
<div>> such groups of pictures without any change.</div>
<div>></div>
<div>> But more simply, if I want an average of each 16x16 icon, I don't need to go</div>
<div>> 5-dimensional, I can just do [#downscale_by 16 smoothly] and that's all.</div>

<div>> I'd like to know what it takes for you to call something «essential». Do you</div>
<div>> mean that there is no other way to do it with Pd, or just no other way to do</div>
<div>> with with PDP ?</div>

<div>> There's [#in~], which is rather experimental. It uses [#to~].</div>
