#include <image_ops.h> Ekstrak informasi bentuk gambar berkode JPEG.
Ringkasan
Operasi ini hanya mem-parsing header gambar, jadi jauh lebih cepat daripada DecodeJpeg .
Argumen:
- ruang lingkup: Objek Lingkup
- isi: 0-D. Gambar berkode JPEG.
Atribut opsional (lihat Attrs ):
- output_type: (Opsional) Jenis keluaran operasi (int32 atau int64). Defaultnya adalah int32.
Pengembalian:
-
Output : 1-D. Bentuk gambar dengan format [tinggi, lebar, saluran].
