Abstract
As for the problem that image synthesis result is subj ect to color and weight selection,the paper proposes an image synthesis algorithm based on sampling cutout and adaptive color weight by combining the advantages of gradient domain and linear alpha synthesis algorithm.This algorithm in-creases data item constraints and neighborhood restrictions to realize the local iteration correction of alpha matte value obtained through the original cutout method.The synthesis area is divided according to the obtained alpha matte value.Different synthesis strategies are adopted for different synthesis ar-eas.Gradient domain synthesis method is used for seamless docking and color fidelity of borders.Be-sides,an equation is re-created with mean interpolation and then the solution is obtained.Thereby, the solving process is simplified.For the internal area,the adaptive color weight is calculated with the use of brightness contrast factor.Besides,the colors of the internal area are further balanced so as to ensure the perfect integration of source image and target image.The simulation experiment shows that the algorithm achieves more effective color maintenance while creating the seamless border than other synthesis algorithms.关键词
