ee.Image.unmix
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
通过计算伪逆并将其乘以每个像素，使用给定的端元对每个像素进行解混。返回一个双精度型图片，其波段数与端元数相同。
| 用法 | 返回 |
|---|
Image.unmix(endmembers, sumToOne, nonNegative) | 图片 |
| 参数 | 类型 | 详细信息 |
|---|
此：image | 图片 | 输入图片。 |
endmembers | 列表 | 要进行非混合的端元。 |
sumToOne | 布尔值，默认值：false | 将输出限制为总和为 1。 |
nonNegative | 布尔值，默认值：false | 将输出限制为非负数。 |
