TSI6223 Software Testing Assignment Report: Biometric Login System Case Study for Basis Path Testing & Testing Principles

Isolate the user’s head region.
Get the user’s face.
Extract facial features.
Compare features with stored library for a match.
If match is > 90%, then identify user.
Else display error message. Restart process.
