Abstract:
To obtain a scene im ag e o f w ide v iew, a v ideo m osa ic ing m ethod based on affine op tica l flow fie ld is put forward. The object function on the a ffine transform param e ters betw een v ideo fram es is bu ilt acco rd ing to optica l constra int equa tion. Then the a ffine transform param eters a re ca lculated bym in im iz ing the object func tion. Acco rd ing to the ca lcu la ted a ffine transform param ete rs, reg ister ing im ages are rea lized. Im age b lend ing is pu t up to im plem ent video mo sa ic ing w ith these affine transfo rm param eters. Expe rim en tal results using v ideo sequence w ith rea l scene have demonstra ted that the m ethod can e ffective ly avo id inaccu rate m osa icing and obtain betterm osa icing im age.
