Ensure the dataset is correctly referenced and dependencies installed.\n\n## Requirements\n```bash\npip install numpy pandas matplotlib scikit-image scikit-learn opencv-python\n```\n\n## Author\n[Your Name]\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fandreaschatzopoulos%2Fface-landmark-detector","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fandreaschatzopoulos%2Fface-landmark-detector","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fandreaschatzopoulos%2Fface-landmark-detector/lists"}
