| 摘 要： | 介绍了一种新型的自适应图像缩放算法.该算法对图像像素块进行分析,能有效识别出图像的边缘特征.然后对内容为边缘的图像部分实行有向滤波,而对其它图像部分实行双线性滤波,从而克服一般图像缩放算法在缩放图像时将边缘模糊化的问题.对该图像缩放算法进行硬件设计,以Verilog实现该算法并在通过前仿验证.

| Abstract: | In this paper,a new kind of adaptive image scaling algorithms is presented.The algorithms analyze the block pattern of an image and thus detect the edge information.The image parts which contain the edge information will be applied the directional interpolation,while other parts will be applied bilinear interpolation.Hardware architecture which implements the algorithms is also described. |

| Keywords: | edge detection adaptive bilinear interpolation picture zooming |
