DetectFacesAsync(SoftwareBitmap, BitmapBounds)	以非同步方式偵測指定搜尋區域內所提供 SoftwareBitmap 中的臉部。

DetectFacesAsync(SoftwareBitmap)

以非同步方式偵測所提供 SoftwareBitmap中的臉部。

public:
 virtual IAsyncOperation<IVector<DetectedFace ^> ^> ^ DetectFacesAsync(SoftwareBitmap ^ image) = DetectFacesAsync;

/// [Windows.Foundation.Metadata.Overload("DetectFacesAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<IVector<DetectedFace>> DetectFacesAsync(SoftwareBitmap const& image);

[Windows.Foundation.Metadata.Overload("DetectFacesAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<IList<DetectedFace>> DetectFacesAsync(SoftwareBitmap image);

function detectFacesAsync(image)

Public Function DetectFacesAsync (image As SoftwareBitmap) As IAsyncOperation(Of IList(Of DetectedFace))

參數

image

SoftwareBitmap

要處理以進行臉部偵測的影像資料。

傳回

IAsyncOperation<IVector<DetectedFace>>

IAsyncOperation<IList<DetectedFace>>

非同步作業，會在成功完成時傳回 DetectedFace 物件的清單。

屬性

OverloadAttribute RemoteAsyncAttribute

備註

提供的 SoftwareBitmap 必須是這個方法及其多載的支援像素格式。 使用 GetSupportedBitmapPixelFormats 擷取目前裝置支援的像素格式清單。 使用 IsBitmapPixelFormatSupported 來測試是否支援指定的像素格式。

/// [Windows.Foundation.Metadata.Overload("DetectFacesWithSearchAreaAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
