Facial Recognition with Siamese Network

Computer vision and deep learning

One-Shot Face Recognition

A CNN-based Siamese Network for one-shot facial recognition, trained with contrastive learning and optimized data pipelines using TensorFlow, OpenCV, NumPy, and Matplotlib.

98%Recognition accuracy achieved in project evaluation.
17%Reduction in training time through data pipeline optimization.
13,000+Faces available in the Labeled Faces in the Wild dataset.
One-shotDesigned to compare identity similarity with limited examples.

Problem

Face recognition often has limited examples per person

Traditional classification models need many labeled examples per identity. A Siamese Network learns similarity instead, making it useful for verification tasks where only one or a few reference images are available.

Pairwise learning

The model learns whether two face images belong to the same identity rather than predicting a fixed class label.

Contrastive signal

Positive and negative image pairs help the network learn a distance space where similar faces stay close.

Practical use cases

The approach fits access control, personal device unlocking, camera systems, and lightweight identity verification flows.

Model

Architecture

The model uses an input size of 105 x 105 x 3, convolution and pooling blocks, an L1 distance layer, and a fully connected prediction head with sigmoid output.
