recognizer.addFaces gives "Process finished with exit code -529697949"

[ArnabBanerji]

I am creating an array of ImageRGB and I have a unique name to be added.

const fr = require('face-recognition');
const fs = require('fs');
const recognizer = fr.FaceRecognizer();
const fileDataFaceMapped = require('./fileDataFaceMapped.json'); //Contains Data

Same :(

[ArnabBanerji]

I was getting the same error. I tried something and it worked (kind of). The thing is that if your face image files are less than 100x100 (min width 100, min height 100), it throws this error. I devised a way to avoid faces that are less than these specs. Do let me know if this worked!

[justadudewhohacks]

Ahh yes, the smallest size I was able to use were 105x105 sized images. Everything below that size seems to crash the application.

Tks ArnabBanerji . It worked.
