The algorithm was used cross-correlation method to obtain initial results for optical-flow processing. Optical-flow was applied to obtain refined results and the resolution of the image reached to unit of pixel. The hybrid algorithm was then applied for systematic images generated by in-house code. The results showed that the algorithm could overcome disadvantage of cross-correlation and optical-flow methods, which indicated by high resoultion and high accurate velocity fields.
