Face Recognition with PCA

Implemented with modern C++

Build Prerequisite

• C++20 support
• OpenCV library

Example Usage

• For training dataset

./pca_train <dataset_path>
>>
./pca_train ./dataset/train

• For recognition

./recognize <test_path> <eigens_path> <dataset_path>
./recognize <eigens_path> <dataset_path> (using camera)
>>
./recognize ./dataset/test ./eigens ./dataset/train
./recognize ./eigens ./dataset/train

Some Example Results

• Accuracy of the sample test dataset:

Notes

• Images need to be saved in a subfolder in the path to the dataset, assuming the subfolder name is the corresponding subject name
  e.g. subject1 is the subject name of path ./dataset/train/subject1
