ee.Image.unmix
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
使用指定端成員取消混合每個像素，方法是計算偽反矩陣，然後將每個像素乘以該矩陣。傳回雙精度浮點數的圖片，頻帶數量與端元相同。
| 用量 | 傳回 |
|---|
Image.unmix(endmembers, sumToOne, nonNegative) | 圖片 |
| 引數 | 類型 | 詳細資料 |
|---|
這個：image | 圖片 | 輸入圖片。 |
endmembers | 清單 | 要取消混合的端部成員。 |
sumToOne | 布林值，預設值為 false | 將輸出內容限制為總和為一。 |
nonNegative | 布林值，預設值為 false | 將輸出內容限制為非負數。 |
