摘　　要：为了轻松实现利用Windows自带绘图程序绘制图形的操作,本文主要利用MATLAB编程对图形进行任意缩放,再利用灰度阀值对图形进行去噪,并把该去噪方法与其他去噪方法进行对比分析。对比结果表明,该方法明显优于其他去噪方法。In order to easily achieve the use of Windows built-in drawing program to draw the graphics noise and zoom, so as to quickly achieve the goal of beautifying illustrations and saving space, this paper mainly uses programming, the graphics Arbitrary Zoom, then the gray threshold is used to denoise the image, and the method is compared with other denoising methods. The comparison results show that this method is obviously superior to other denoising methods.

关 键 词：缩放 去噪 灰度 阀值
