C&#8217;est d&#8217;ailleurs au d\u00e9tour d&#8217;un chemin que nous sommes tomb\u00e9s en arr\u00eat&#8230; prolong\u00e9 devant un sp\u00e9cimen de cornouiller prodigieux. On a commenc\u00e9 par prendre la photo de l&#8217;\u00e9tiquette en tremblotant mais, pas de chance, impossible de la lire ensuite car tout \u00e9tait flou. <\/p>\n\n\n\n<p>Heureusement j\u2019ai pu appeler mon copain Norbert Wiener \u00e0 la rescousse. Vous ne le connaissez pas ? C\u2019est un expert de la d\u00e9convolution.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/jardinsamoena.be\/wp-content\/uploads\/2019\/05\/DSC_8327-1024x683.jpg\" alt=\"\" class=\"wp-image-720\" srcset=\"https:\/\/jardinsamoena.be\/wp-content\/uploads\/2019\/05\/DSC_8327-1024x683.jpg 1024w, https:\/\/jardinsamoena.be\/wp-content\/uploads\/2019\/05\/DSC_8327-300x200.jpg 300w, https:\/\/jardinsamoena.be\/wp-content\/uploads\/2019\/05\/DSC_8327-768x512.jpg 768w, https:\/\/jardinsamoena.be\/wp-content\/uploads\/2019\/05\/DSC_8327-450x300.jpg 450w, https:\/\/jardinsamoena.be\/wp-content\/uploads\/2019\/05\/DSC_8327.jpg 1620w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Malgr\u00e9 son nom qui pr\u00eate \u00e0 confusion, ce syst\u00e8me ne permet pas d\u2019enrayer la multiplication des imb\u00e9ciles sur la Terre mais presque.<\/p>\n\n\n\n<p>&nbsp;Il s\u2019agit d\u2019une op\u00e9ration math\u00e9matique qui vise \u00e0 \u00e9liminer les bruits dans un signal et donc d\u2019enlever le flou d\u2019une photo par exemple.

Regardez la photo qu\u2019on a prise en tremblant. M\u00eame la mouche \u00e0 caca sur le coin inf\u00e9rieur gauche de la photo\u00a0en a perdu son lustre iris\u00e9 pour s&#8217;harmoniser avec le noir de l&#8217;\u00e9tiquette. Bon, elle est encore un peu floue&#8230; mais c&#8217;est de la d\u00e9convolution.<\/p>\n\n\n\n<p>Voici donc le sp\u00e9cimen Cornus kousa &#8216;John Slocock&#8217; dans toute sa splendeur. Le cultivar est connu pour crouler sous le poids des bract\u00e9es puis des fruits ros\u00e9s de la taille d&#8217;une fraise et adopter de belles couleurs \u00e0 l&#8217;automne.
