Modifier et passer en couleurs avec Gimp&lt;/h2&gt;
&lt;p&gt;Un r&#233;sum&#233; en vid&#233;o :&lt;/p&gt;
&lt;div class=&#034;player-container&#034;&gt; &lt;iframe class=&#034;yplayer&#034; id=&#034;player&#034; width=&#034;720&#034; height=&#034;480&#034; type=&#034;text/html&#034; src=&#034;https://www.youtube.com/embed/7ISTwBWqhC8?version=3&amp;enablejsapi=1&amp;playerapiid=ytplayer&amp;wmode=transparent&amp;modestbranding=1&amp;rel=0&amp;fs=1&amp;showinfo=1&#034; frameborder=&#034;0&#034; allowfullscreen webkitallowfullscreen mozallowfullscreen allowscriptaccess=&#034;always&#034; &gt;&lt;/iframe&gt; &lt;/div&gt;&lt;h2 class=&#034;spip&#034;&gt;
Filtres et fonctions de r&#233;f&#233;rence avec Python&lt;/h2&gt;
&lt;p&gt;Voici les trois images issues de 3 filtres diff&#233;rents (apr&#232;s une premi&#232;re retouche) :&lt;/p&gt;
&lt;div class='spip_document_658 spip_document spip_documents spip_document_image spip_documents_center spip_document_center'&gt;
&lt;figure class=&#034;spip_doc_inner&#034;&gt; &lt;img src='https://tableauxmaths.fr/local/cache-vignettes/L500xH296/carene_red_small-f415c.png?1789040840' width='500' height='296' alt='' /&gt;
&lt;/figure&gt;
&lt;/div&gt;&lt;div class='spip_document_663 spip_document spip_documents spip_document_image spip_documents_center spip_document_center'&gt;
&lt;figure class=&#034;spip_doc_inner&#034;&gt; &lt;img src='https://tableauxmaths.fr/local/cache-vignettes/L500xH296/carene_green_small-2ca3e.png?1789040840' width='500' height='296' alt='' /&gt;

&lt;/div&gt;
&lt;p&gt;On peut ensuite appliquer des fonctions filtres (T&#233;l&#233;chargez les 3 images pr&#233;c&#233;dentes et modifiez le chemin et les noms) :&lt;/p&gt; &lt;textarea readonly='readonly' cols='40' rows='102' class='spip_cadre spip_cadre_block' dir='ltr'&gt;import matplotlib.pyplot as plt from PIL import Image import numpy as np #Import de l'image: img = Image.open(&#034;Carene_RED_small.png&#034;) #Cr&#233;ation des nouvelles images vides: img1 = Image.new(&#034;I&#034;, img.size) img2 = Image.new(&#034;I&#034;, img.size) img3 = Image.new(&#034;I&#034;, img.size) img4 = Image.new(&#034;I&#034;, img.size) img5 = Image.new(&#034;I&#034;, img.size) #Numpy 2D array : data = np.array(img.getdata()) #Formatage 0-1 data = data/max(data) #Fonctions filtres: def resserrer(x): return 4*(x-0.5)**3 + 0.5 def racine(x): return np.sqrt(x) def carre(x): return x*x def contraste(x): return x*(-2*x**2 + 3*x) def renverser(x): return 1-x #Modifications: data1 = contraste(data) data2 = resserrer(data) data3 = carre(data) data4 = racine(data) data5 = renverser(data) #Remplissage de l'ancienne image et des nouvelles en 0-255: img.putdata(255*data) img1.putdata(255*data1) img2.putdata(255*data2) img3.putdata(255*data3) img4.putdata(255*data4) img5.putdata(255*data5) #Affichage fig = plt.figure(figsize=(12, 20)) fig.add_subplot(6, 2, 1) plt.imshow(img) plt.title(&#034;Originale&#034;) fig.add_subplot(6, 2, 2) t = np.arange(0., 1., 0.1) plt.plot(t, t, 'r--') plt.axis('square') fig.add_subplot(6, 2, 3) plt.imshow(img1) plt.title(&#034;Contraste&#034;) fig.add_subplot(6, 2, 4) t = np.arange(0., 1., 0.1) plt.plot(t, contraste(t), 'r--', t, t, 'b--') plt.axis('square') fig.add_subplot(6, 2, 5) plt.imshow(img2) plt.title(&#034;Resserrer&#034;) fig.add_subplot(6, 2, 6) t = np.arange(0., 1., 0.1) plt.plot(t, resserrer(t), 'r--', t, t, 'b--') plt.axis('square') fig.add_subplot(6, 2, 7) plt.imshow(img3) plt.title(&#034;Carr&#233;e&#034;) fig.add_subplot(6, 2, 8) t = np.arange(0., 1., 0.1) plt.plot(t, carre(t), 'r--', t, t, 'b--') plt.axis('square') fig.add_subplot(6, 2, 9) plt.imshow(img4) plt.title(&#034;Racine&#034;) fig.add_subplot(6, 2, 10) t = np.arange(0., 1., 0.05) plt.plot(t, racine(t), 'r--', t, t, 'b--') plt.axis('square') fig.add_subplot(6, 2, 11) plt.imshow(img5) plt.title(&#034;Renverser&#034;) fig.add_subplot(6, 2, 12) t = np.arange(0., 1., 0.05) plt.plot(t, renverser(t), 'r--', t, t, 'b--') plt.axis('square') plt.show()&lt;/textarea&gt;&lt;div class='spip_document_661 spip_document spip_documents spip_document_image spip_documents_center spip_document_center spip_document_avec_legende' data-legende-len=&#034;53&#034; data-legende-lenx=&#034;x&#034;
