问题描述
这是我的script.js：
$(document).ready(function(){
start()
})
const mtcnnParams = {
// number of scaled versions of the input image passed through the CNN
// of the first stage,lower numbers will result in lower inference time,// but will also be less accurate
maxNumScales: 10,// scale factor used to calculate the scale steps of the image
// pyramid used in stage 1
scaleFactor: 0.709,// the score threshold values used to filter the bounding
// boxes of stage 1,2 and 3
scoreThresholds: [0.6,0.7,0.7],// mininum face size to expect,the higher the faster processing will be,// but smaller faces won't be detected
minFaceSize: 20
}
async function start() {
// load the models
await faceapi.loadMtcnnModel('/models')
await faceapi.loadFaceRecognitionModel('/models')
const videoEl = document.getElementById('inputVideo')
navigator.getUserMedia(
{ video: {} },stream => videoEl.srcObject = stream,err => console.error(err)
)
const mtcnnResults = await faceapi.mtcnn(document.getElementById('inputVideo'),mtcnnForwardParams)
// faceapi.drawDetection('overlay',mtcnnResults.map(res => res.faceDetection),{ withScore: false })
// faceapi.drawLandmarks('overlay',mtcnnResults.map(res => res.faceLandmarks),{ lineWidth: 4,color: 'red' })
const options = new faceapi.MtcnnOptions(mtcnnParams)
const input = document.getElementById('inputVideo')
const fullFaceDescriptions = await faceapi.detectAllFaces(input,options).withFaceLandmarks().withFaceDescriptors()
const labels = ['arif']
const labeledFaceDescriptors = await Promise.all(
labels.map(async label=>{
const img = await faceapi.fetchImage(
'https://github.com/ahmedarifhasan/adasd/blob/master/Test.jpg'
)
const fullFaceDescription = await faceapi.detectAllFaces(img).withFaceLandmarks().withFaceDescriptors()
if (!fullFaceDescription) {
throw new Error(`no faces detected for ${label}`)
}
return new faceapi.LabeledFaceDescriptors(label,fullFaceDescription)
})
)
const maxDescriptorDistance = 0.6
const faceMatcher = new faceapi.FaceMatcher(labeledFaceDescriptors,maxDescriptorDistance)
const results = fullFaceDescription.map(fd => faceMatcher.findBestMatch(fd.descriptor))
results.forEach((bestMatch,i) => {
const box = fullFaceDescriptions[i].detection.box
const text = bestMatch.toString()
const drawBox = new faceapi.draw.DrawBox(box,{ label: text })
drawBox.draw(canvas)
})
}
async function onPlay(videoEl){
start()
setTimeout(()=>onPlay(videoEl))
}
const mtcnnForwardParams = {
// number of scaled versions of the input image passed through the CNN
// of the first stage,// but smaller faces won't be detected
minFaceSize: 20
}

我对此并不陌生，必须识别网络摄像头中该人的面孔。非常感谢您的帮助。
另外，在我看来，face-api.js比其他软件包要强一些，因此在回答时请保持礼貌。 我已将图片上传到Github，并使用该链接进行识别。
