The Successive Abandonment Method for fast PIV analysis is improved both in speed and reliability. The improvement is achieved through following three points : selecting characteristic pixels prior to the successive abandonment analysis, calculation order optimization in accumulating absolute differences, estimation method of displacement. Accordingly, the performance of the new algorithm shows at least 50% reduction in analysis time, and erroneous vectors becomes fewer comparatively.
