The Eyeball Algorithm is a method used in the field of computer vision and image processing to detect and track human eyes in images or video frames. It is particularly useful in applications such as facial recognition, gaze tracking, and human-computer interaction. The algorithm typically involves several key steps:

First, the algorithm preprocesses the input image to enhance features that are relevant to eye detection, such as edges and contrast. This is often achieved through techniques like histogram equalization and Gaussian blurring.

Next, the algorithm applies a feature extraction method to identify potential eye regions. Common techniques include the use of Haar-like features, which are rectangular patterns that can capture the distinctive shape of eyes. These features are then used to train a classifier, such as an AdaBoost or Support Vector Machine (SVM), to distinguish eye regions from other parts of the image.

Once potential eye regions are identified, the algorithm refines these regions using more detailed analysis. This may involve techniques such as template matching, where known eye templates are compared to the detected regions, or more advanced methods like deep learning, where convolutional neural networks (CNNs) are used to classify eye regions with high accuracy.

Finally, the algorithm verifies the detected eye regions to ensure they are indeed eyes and not false positives. This can be done through various methods, such as checking the aspect ratio of the detected regions or using additional contextual information from the surrounding facial features.

The Eyeball Algorithm has been widely adopted in various applications due to its robustness and accuracy. However, it is important to note that the performance of the algorithm can be affected by factors such as lighting conditions, occlusions, and variations in facial expressions. Therefore, ongoing research and development are focused on improving the algorithm's robustness and accuracy in different scenarios.
