DecodeGif
Zadbaj o dobrą organizację dzięki kolekcji
Zapisuj i kategoryzuj treści zgodnie ze swoimi preferencjami.
Dekoduj klatki obrazu zakodowanego w formacie GIF do tensora uint8.
Obrazy GIF z kompresją ramki lub przezroczystości nie są obsługiwane. W systemach Linux i MacOS przekonwertuj animowane pliki GIF ze skompresowanych na nieskompresowane, uruchamiając:
konwertuj $src.gif -coalesce $dst.gif
Ta opcja obsługuje także dekodowanie plików JPEG i PNG, choć wygodniej jest używać tf.io.decode_image .

Metody publiczne
publiczne wyjście < TUint8 > asOutput ()
Zwraca symboliczny uchwyt tensora.
Dane wejściowe operacji TensorFlow są wynikami innej operacji TensorFlow. Ta metoda służy do uzyskania symbolicznego uchwytu reprezentującego obliczenia danych wejściowych.
Metoda fabryczna służąca do tworzenia klasy opakowującej nową operację DecodeGif.
