检测置信度 [英] detect confidence level

问题描述

您好，

关于以下文档：

DetecFaces方法中的pFaces参数应返回[0,1中的值] ]。

the pFaces argument in the DetecFaces method should return a value in [0, 1].

当我使用这种方法时，我得到的值超出了这个间隔。应该导致什么？如何在[0,1]中对它们进行标准化？

When I am using this method, I am getting values beyond this interval. What should be causing it? How can I normalize them in [0, 1]?

下面的代码片段如下：

// Do face tracking
        if (SUCCEEDED(hrCopy))
        {
            FT_SENSOR_DATA sensorData(m_colorImage, m_depthImage, m_pKinectSensor->GetZoomFactor(), m_pKinectSensor->GetViewOffSet());

            FT_VECTOR3D* hint = NULL;
            if (SUCCEEDED(m_pKinectSensor->GetClosestHint(m_hint3D)))
            {
                hint = m_hint3D;
            }
            if (m_LastTrackSucceeded)
            {
                hrFT = m_pFaceTracker->ContinueTracking(&sensorData, hint, m_pFTResult);
            }
            else
            {
                hrFT = m_pFaceTracker->StartTracking(&sensorData, NULL, hint, m_pFTResult);
            }

			RECT roi;
			HRESULT hr = m_pFTResult->GetFaceRect(&roi);
			bool  hasFoundFace = (SUCCEEDED(hr) && (roi.bottom != roi.top && roi.left != roi.right));
			FT_WEIGHTED_RECT* faceConfidence = new FT_WEIGHTED_RECT();
			UINT pFaceCount = 1;
			hr = m_pFaceTracker->DetectFaces(&sensorData, hasFoundFace ? &roi : NULL, faceConfidence, &pFaceCount);
			if (SUCCEEDED(hr) && hasFoundFace)
			{
				m_faceConfidence = faceConfidence->Weight;
			}
			delete faceConfidence;
        }

推荐答案

你在检查m_pFTResult是成功？

Are you checking that the m_pFTResult was successful?

if(SUCCEEDED(hrFT) && SUCCEEDED(m_pFTResult->GetStatus()))
{
    // detect code
}
