| 摘 要： | 提出一种在传统插值图像基础上,对高分辨率图像进行边缘检测算法.该算法处理RGB彩色图像时,先进行色融合,再检测;然后根据边缘多方向梯度特征,对边缘邻接像素点作优化处理.在多倍插值放大时,采用小步长倍率递进方式.实验结果表明,算法模型简单易于实现,消除了传统图像插值算法边缘锯齿和模糊,保持了图像边缘细节和纹理特征,对彩色图像视觉效果更为明显. |

| Abstract: | Based on the conventional interpolation image,high-resolution image's edges were obtain using edge detector method.If the image was combined by RGB,color fusion should be processed first.Then optimized the edge's neighbors based on max-gradient character of the edge's multi-direction.Multi-time magnification uses small step-up ratio method.Ex- perimental results demonstrate that this algorithm model is terse and realizable easily,the blur and jaggy of image detail are avoided.The visual quality of the color interpolated images is more prominent. |
| Keywords: | image interpolation magnification edge detection gradient |
