Improved Iteration Centroid Algorithm Based on Linear CCD Light-spot Location

摘要：

In order to increase the linear CCD light-spot location accuracy and strengthen the ant-noise ability of centroid algorithm, an improved algorithm is presented. According to the symmetry distribution and high gray value of the object region, squared weight method and linear interpolation are used to enhance the effect of object region. Meanwhile, linear interpolation and iteration algorithm are utilized to improve the resolution and accuracy on signal segmentation. The simulation result shows that it is more accurate and stable than other sub-pixel algorithm, and the satisfying result is obtained
