Die Background Remover API ermöglicht die Integration KI-gestützter Hintergrundentfernung in Ihre Anwendungen. Entfernen Sie Hintergründe aus Bildern und Videos programmatisch mit einfachen REST-API-Aufrufen.

Um loszulegen, registrieren Sie sich für einen API-Schlüssel unter Entwicklerportal

API-Parameterreferenz

Folgende Parameter können in Ihre API-Anfragen aufgenommen werden. Alle Datei-Uploads unterstützen große Dateien ohne praktische Größenbeschränkung.

Bildverarbeitungsparameter

ParameterTypStandardBeschreibung
convert_tostringerforderlichAuf „Bild-Hintergrundentferner“ einstellen
modelstringu2netKI-Modell: u2net (allgemeine Objekte/Menschen/Dinge), u2net_human_seg (optimiert für Menschen), u2netp (schnell/leichtgewichtig)
alpha_mattingbooleanfalseAktivieren Sie die Alpha-Matte für schärfere Kanten bei Haaren und feinen Details.
alpha_fgint240Vordergrundschwelle (0–255). Höherer Wert = strengere Vordergrunderkennung
alpha_bgint10Hintergrundschwellenwert (0–255). Niedrigerer Wert = strengere Hintergrunderkennung
alpha_erodeint10Größe der Kantenerosion (1-25). Steuert die Kantenschärfe
alpha_base_sizeint1000Basisgröße für die Alpha-Matting-Verarbeitung. Höher = bessere Qualität, aber langsamer.
only_maskbooleanfalseSchwarze/weiße Maske anstelle des transparenten Bildes zurückgeben
bg_typestringtransparentHintergrundtyp: transparent, farbig oder Bild
bg_color_valuestring#ffffffHintergrundfarbe im Hexadezimalformat (wenn bg_type=color)

Videoverarbeitungsparameter

ParameterTypStandardBeschreibung
convert_tostringerforderlichAuf Video-Hintergrundentferner einstellen
modelstringu2netKI-Modell: u2net (allgemein), u2net_human_seg (Menschen), u2netp (schnell)
video_formatstringmovAusgabeformat: mov (transparent), mattekey (mp4-Matte), gif (animiert), Video über Bild, Video über Video, gif mit Hintergrund, mp4 mit Farbe
alpha_mattingbooleanfalseAktivieren Sie die Alpha-Maskierung für schärfere Kanten.
alpha_fgint240Vordergrundschwelle (0-255)
alpha_bgint10Hintergrundschwelle (0-255)
alpha_erodeint10Randerosionsgröße (1-25)
alpha_base_sizeint1000Basisgröße für die Alpha-Matting-Verarbeitung
video_bg_color_enabledbooleanfalseEinfarbigen Hintergrund aktivieren (für das Format mp4_with_color)
video_bg_colorstring#00ff00Hintergrundfarbe im Hexadezimalformat
framerateintautoBenutzerdefinierte Ausgabebildrate (1–60 FPS). Lassen Sie dieses Feld leer, um die Bildrate an das Eingangsvideo anzupassen.
frame_limitintnoneDie Verarbeitung ist auf die ersten N Frames beschränkt. Nützlich zum Testen oder Erstellen von Clips.
