Light Compensation-Based Face Detection

In this light compensation-based face detection technology, we first perform illumination compensation on the image to enhance detection accuracy and stability. Light compensation is a common image enhancement technique that improves image quality by adjusting brightness and contrast levels, typically implemented through histogram equalization or gamma correction algorithms.

Following illumination correction, we integrate skin tone and hair color information using color space transformations (such as converting RGB to YCbCr or HSV) to extract characteristic ranges for facial features. By leveraging these color-based features, we can more accurately locate and identify facial regions through morphological operations and connected component analysis.

This methodology demonstrates wide application potential in image processing domains, including facial recognition systems, expression analysis algorithms, and facial beautification applications. The implementation typically involves OpenCV functions for histogram manipulation and color thresholding, combined with region proposal networks for precise facial boundary detection.
