Bitmap amplification, the author of this paper, based on the PM - MF puts forward a new kind of magnification method, and applied to the bitmap amplifier, improved amplifies the effect of a bitmap. New bitmap amplification method combined with P - M model, add the median filtering, formed the PM - MF model, on the basis of this model innovation proposed the fuzzy image processing. Got a magnified the bitmap algorithm, makes the image more clear, amplification effect is better. Based on the MATLAB software programming to achieve the three classical model: the nearest neighbor interpolation, the bilinear interpolation and bicubic interpolation on the amplification bitmap processing, has realized the P - M model, PM - MF model to enlarge the bitmap handle. And we design the new way also implements the bitmap bitmap handle amplification processing. And he passed the test. 目录 目录 问题重述……………………………………………………………………………2 1.1知识背景……………………………………………………………………….2 1.2问题的提出…………………………………………………………………….2 二、问题分析……………………………………………………………………………2 2.1将位图进行放大……………………………………………………………….2 2.2放大后的图像质量…………………………………………………………….2 三、模型的假设…………………………………………………………………………2 四、符号说明…………………………………………………………………………....3 五、模型的建立与求解…………………………………………………………………3 5.1线性算法分析………………………………………………………………….4 5.1.1最近邻插值…………………………………………………………….4 5.1.2双线性插值…………………………………………………………….5 5.1.3双立方插值…………………………………………………………….5 5.1.4线性偏微分方程算法分析…………………………………………….6 5.2非线性偏微分图像放大方法………………………………………………….7 5.3放大图像中的阶梯和噪音处理……………………………………………….10 5.4放大图像边缘处理………………
