Hallo zusammen.
Ich werde auch heute weiterhin interessante KI-Projekte mit Ihnen teilen.
Das letzte Mal haben wir die Verwendung von GAN (Generative Adversarial Network)um statische Bilder zu bewegenveröffentlicht.
Heute zeigen wir Ihnen, wie Sie die Bildverbesserungstechnologie von NoGAN verwenden, um alte Fotos einzufärben. Der Effekt ist wie folgt:

Nach dem Färben #🎜 🎜#
NoGAN ist eine neue Art von GAN, bei der das GAN-Training am wenigsten Zeit in Anspruch nimmt. Das heute geteilte Projekt ist bereits ein Open-Source-Projekt auf GitHub. Lassen Sie es uns ausführen. 1. VorbereitungVerwenden Sie zunächst den Befehl „git clone“, um den Quellcode herunterzuladen.git clone https<span style="color: rgb(89, 89, 89); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">:</span><span style="color: rgb(215, 58, 73); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">//</span>github<span style="color: rgb(0, 92, 197); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">.com</span><span style="color: rgb(215, 58, 73); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">/</span>jantic<span style="color: rgb(215, 58, 73); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">/</span>DeOldify<span style="color: rgb(0, 92, 197); margin: 0px; padding: 0px; background: none 0% 0% / auto repeat scroll padding-box border-box rgba(0, 0, 0, 0);">.git</span>

Verwenden Sie cv2, um alte Fotos zu lesen, und verwenden Sie das PIL.Image-Modul, um die Bilder in das für die Modelleingabe erforderliche Format zu konvertieren. und senden Sie sie. Importieren Sie das Modell zum Ausmalen und speichern Sie es, wenn Sie fertig sind.
Der obige Code wird aus dem Quellcode des Projekts extrahiert. Wie Sie sehen, ist die Ausführung des Codes sehr einfach.
Das obige ist der detaillierte Inhalt vonPython+AI koloriert alte Fotos. Für weitere Informationen folgen Sie bitte anderen verwandten Artikeln auf der PHP chinesischen Website!
