Standard images for wake bubble processing method

A new wake bubble processing method based on standard images is developed. The distribution, size, population, movement of bubbles in ship wakes are most important characteristic influencing the sonic, optical, conductive and other signatures of ship wakes as information sources for detecting and tracing moving target in sea. The intuitive and effective method to get the parameters of wake bubbles is optical imaging. Standard bubble images can be one of the means of evaluating the performance of imaging processing method. The standard sequence bubble images are generated which the size, velocity, position of bubbles and the width of laser sheet are known and can be changed. The effectiveness and accuracy of the wake bubble image processing method can be evaluated by standard images.
