To eliminate the influence of temperature on the alignment precision of chips and substrates in the process of thermosonic flip-chip bonding,the image dithering caused by heating must be controlled in sub-pixel scope.

By collecting a large number of images at different temperatures and adopting many different image movement computing methods with different accuracy levels, the image distortion and the image dithering rule under the influence of turbulence were analyzed.

A new video segmentation algorithm for data captured with possible camera vibrations was proposed.
