Checkerboard Pattern Examples with Grid Analysis #1529200 (License: Personal Use)

The image displays three distinct checkerboard configurations: a full 5×5 blue-and-white pattern, a similar pattern with a central white square removed, and a large empty grid for comparison. Each uses consistent square sizing and alignment to demonstrate geometric principles such as periodicity, symmetry, and modular tiling. The grids emphasize structural relationships useful in graphic design, computer vision, and educational contexts.

Used in educational materials on geometry, pattern recognition, or UI/UX design tutorials; supports explanations of tessellation, pixel grids, or calibration targets (e.g., chessboard calibration in OpenCV).
