Color, Skin, and Finger Detection in Images

Source Image	Skin Detection

Note: Skin Detection with HSV color space filtering might not work for all skin tones

Install requirements

With poetry (Recommended):

poetry install

With venv:

python -m venv venv; source venv/bin/activate
pip install -r requirements.txt

Webcam fingertip detection

# runs finger detection on the webcam, Press z when fingers are visible in the 9 squares
python skin_and_finger_detection/video_fingertip_detection.py

Webcam skin detection based on YCrCb Color Space

# displays the original webcam screen and the skin detection result screen
python skin_and_finger_detection/video_skin_detection.py

Choose a HSV color space filter threshold on an image

# move sliders to find the optimal threshold for detecting different colors in image
python color_detection/image_hsv_threshold_picker.py -i <IMAGE_PATH>

Filter colors in video using HSV color space filters

python color_detection/video_color_detection.py -v <VIDEO_PATH>
