摘要
图像处理中对于图像放大常使用双线性插值算法,其运行的快慢直接关系到实时图像处理的速度.文中在多核计算机上设计了双线性插值并行程序,实现了图像放大的快速处理.充分利用多核技术提升多核处理器的资源利用率,缩短执行时间,发挥多核系统的优异性能.实验结果可看出,文中算法对于大规模图像放大呈现出良好的加速处理能力,表明了双线性插值多核并行算法在实时放大图像的应用中是有效及可行的.
Image processing often used bilinear interpolation algorithm to zoom images, its speed directly related to the real--time image processing speed. In multicore computer designed a bilinear interpolation parallel program, achieved to high speed process of image zooming. Full use of multicore technology to enhance the resource utilization of multicore processors, shorten the execution time and played superior performance of multicore system. Through experiment results, it can he seen that this algorithm showed a good ability in accelerate large image processing, indicate the bilinear interpolation multieore parallel algorithm in application of real--time image zooming is effective and feasible.
