%X In the digital image correlation method,the first step to obtain the displacements of each point in the images taken before and after deformation was to confirm its integer pixel displacement,then to compute its sub-pixel displacement using the correlation coefficient of the integer pixel.A new computing method about the integer pixel was developed,which was by using weighted window to compute the integer pixel displacement of each point.The numerical simulation results show that it can improve the displacement accuracy.
