Template Matching for Eye Localization

Template matching image recognition can be applied to eye localization, character matching, machine part identification, etc. It constitutes a fundamental processing method in the image processing field suitable for various industrial environments. The core technology involves spatially aligning multiple images of the same scene captured under different conditions and searching for predefined patterns using correlation-based algorithms. Implementation typically involves sliding-window approaches with similarity metrics like cross-correlation or sum of squared differences (SSD) calculations.
