Abstract: According to Image Quilting for texture synthesis algorithm characteristic that the new and old texture pieces spliced,a parallel programming model that creating multi-task realized the texture pieces to cut and splice was studied to Image Quilting for texture synthesis algorithm.A functional module named iq() was designed for the calculation of suture path in the overlapping area,subtasks assigned to each worker executed parallel computing by using of the scheduler of MATLAB multi-core clusters.The experimental results indicated that this algorithm can achieve a better speed-up ratio and enhance the available efficiency of multi-core CPU and promote the utilization rate of multi-core computer resources effectively.
