Recognizing the wrong person

Issue Description
Hi,

After several tests and I managed to capture the evidence.

As you can see, people are different and yet the model puts a similarity of 0.74.
I tested on other sites and models and even the facejs version below your lib doesn't match the two photos.

I am attaching the two photos, for reasons of privacy for both people, could I not leave the images public?

Steps to Reproduce

compare the similarity between the two images

Expected Behavior

Environment
humanConfig = {
debug: false,
modelBasePath: '../assets/models/',
filter: { enabled: true, equalization: true, flip: false, width: 0 },
face: {
enabled: true,
detector: { rotation: true, maxDetected: 1, minConfidence: 0.6, return: true, mask: false, skipFrames: 1, iouThreshold: 0.5 },
iris: { enabled: true },
description: { enabled: true, minConfidence: 0.6, skipFrames: 1 }, // default model for face descriptor extraction is faceres

  //insightface: { enabled: true, modelPath: '../assets/models/insightface-mobilenet-swish.json' }, // alternative model
  mesh: { enabled: true },
  emotion: { enabled: false },
  antispoof: { enabled: false },
  liveness: { enabled: false },
  skipFrames: 1
},
body: { enabled: false },
hand: { enabled: false },
object: { enabled: false },
gesture: { enabled: true },
segmentation: { enabled: false },
async: false

};

• Framework (if any) (e.g. React, NextJS, etc.)? Angular

Diagnostics

• Check out any applicable diagnostic steps

Additional

• For installation or startup issues include your package.json
• For usage issues, it is recommended to post your code as gist
• For general questions, create a discussion topic

this topic has been discussed many times:

• search for more detailed descriptions/conversations - there have been a lot.
• default model for face intentification is choosen because its fast and lightweight,
  not because its precise. use a different model, human supports several just via config change
• tune other params as needed

and other than those 3 large topics, i really don't have much to add so i'm closing the issue for now.
