memverifikasi kelayakan nonkomersial untuk mempertahankan akses Earth Engine.
ee.Image.unmix
Tetap teratur dengan koleksi
Simpan dan kategorikan konten berdasarkan preferensi Anda.
Pisahkan setiap piksel dengan endmember yang diberikan, dengan menghitung pseudo-invers dan mengalikannya melalui setiap piksel. Menampilkan gambar ganda dengan jumlah band yang sama dengan endmember.
| Penggunaan | Hasil |

| Argumen | Jenis | Detail |
|---|
ini: image | Gambar | Gambar input. |
endmembers | Daftar | Anggota akhir untuk memisahkan. |
sumToOne | Boolean, default: false | Batasi output agar berjumlah satu. |
nonNegative | Boolean, default: false | Batasi output agar tidak negatif. |
