Optimization of speckle pattern based on integer programming method

•A mathematical model for finding the subset with the largest sum of square of subset intensity gradients is established.•The optimized speckle patterns for digital image correlation are produced with the integer programming method.•Both the simulations and experiments show that the proposed optimiz...
