The scope of the "Eye Detection Using MATLAB" project involves developing robust algorithms
for accurately detecting eyes in images, considering various factors such as lighting conditions,
facial expressions, and occlusions. The project encompasses algorithm development,
performance evaluation, optimization for computational efficiency, exploration of real-world
applications in fields like facial recognition and driver monitoring systems, thorough
documentation, scalability, and ethical considerations. Through comprehensive exploration
and implementation of these aspects, the project aims to deliver a reliable and versatile eye
detection system that can be applied in diverse scenarios while adhering to ethical principles
and ensuring privacy and fairness.
