Automated Eye Localization in Facial Images with Computer Vision Implementation

This system automatically locates human eye positions in given facial images and marks them visually. Through computer vision techniques like Haar cascades or deep learning-based object detection (using libraries such as OpenCV or Dlib), the algorithm identifies eye regions by analyzing facial landmarks or pattern recognition. The coordinates of detected eyes can be extracted using functions like cv2.CascadeClassifier for Haar features or dlib's shape_predictor for facial landmark detection.

Based on the located eye positions, further facial analysis and feature extraction can be performed, including facial expression recognition and gaze direction estimation using geometric calculations of eye corner points and iris centers. Additionally, this technology enables early screening and diagnosis of ocular diseases such as glaucoma and cataracts by analyzing eye shape abnormalities and pupil characteristics through image processing techniques like threshold segmentation and contour analysis.

With broad application prospects in computer vision and medical fields, this technology significantly enhances the accuracy and efficiency of artificial intelligence systems. Implementation typically involves preprocessing steps (resizing, grayscale conversion), followed by eye detection algorithms that return bounding box coordinates, which can be visualized using rectangle drawing functions (cv2.rectangle) for medical imaging systems or security applications.
