top noise

First, I made a multiply layer on top and added some noise with a textured brush.

首先, 我在上面新建了个multiply(正片叠底)图层,在图层上用画笔添加了些纹理.

The background and object are distinguished clearly in the combined action of the background light and the top light. The image noise filtered after binaryzation processing based on the Otsu algorithm is achieved good result.

在背景光源和上光源的共同作用下，背景和目标很分明，采用Otsu算法对滤波后的图像进行二值化处理也取得了很好的效果。

High equipment, low noise and low oil wear, what make it be the first choice of the top grade European vehicles.

高配置、低噪音、低油耗，是欧版高档踏板摩托车的首选动力。

Noise research has been given more and more attention by many workgroups came from different countries and many reports about this new hotspot had been published on the top level journals, such as Science, Nature, JPC, CPL in the recent decade.

近些年来，许多关于噪声的文章发表在Science，Nature，JPC，CPL等国际一流的刊物上，从一个侧面反映了噪声已经成为一个新兴的研究热点。
