| Abstract: | Interpolation algorithm plays an important role in image processing.The article describes the principle of bilinear interpolation,analysis of floating-point arithmetic constraints on the efficiency of the algorithm proposed by the pixel value convert floating-point operations to enlarge a certain multiple of the shift operator algorithm to accelerate the program,focused on the design to accelerate the interpolation algorithm.Then comparison test about accelerate the algorithm efficiency and image quality is conducted.It is confirmed that the accelerated algorithm can improve interpolation efficiency and ensure image quality.It can be widely used in real-time system. |
