| 摘 要： | 图像放大是 RIP软件中十分重要的环节,其所用插值算法的优劣直接关系着输出图像的质量与速度.利用 Canny算法提取的边缘信息将低分辨率图像分为平坦区域与边缘区域,对非边缘区域采用双线性插值算法,对边缘区域使用沿4相邻降采样点确定的方向进行插值的特殊算法.经实验证明,与经典插值算法相比,放大图像边缘效果更好,且处理速度更快,可实际用于对图像质量与处理效率要求高的 RIP软件

| Abstract: | Image magnification is one of the very important steps in the RIP soft,rare,while the performance of the interpolation algorithm used in image magnification is directly related to the quality and speed of output image, According to the edge information detected by Canny method, the low-resolution image is divided into fiat areas and edge related areas in this algorithm, Then the riot oreas are processed by bilinear interpolation.. And the edge related areas is processed by special interpolation along the edge direction decided by four down-sampled neighbors. Experimental results demonstrate that compared with the classic interpolation algorithm,this algorithm not only improves the visual quality of the edge,but also increases the processing speed,actually useful in the RIP softwere rextuired high quality and high efficiency. |
