Gaussian
打开24位彩色bmp文件, 显示该图像
将图像内容顺时针旋转90度后显示出来
将图像分成等大小的4块,将第1和第3块像素互换后保存
将旋转后的图像转换成灰度图像显示,并保存
对灰度图像求Sobel边缘图,显示出来,并保存
对灰度图像进行Gaussian平滑,并保存(需要体会平滑的作用)
对灰度图像进行2值化(Open 24-bit color bmp files, displays the image will rotate clockwise image content displayed image is divided into four equal-sized 90 degrees, the first and three pixels after swap to save the rotated image conversion ashes of the image display, and save images to grayscale seeking Sobel edge map is displayed, and save the gray image Gaussian smoothing, and save (experience required smoothing effect) grayscale image binarized)

说明: :建立了碳钢渗硫表面和非渗硫表面的多球凸峰面接触模型,模型中,凸峰高度按高斯函数分布.用塑性流线
理论分析了渗硫层的摩擦系数.计算结果表明:摩擦系数随载荷的增加而增加;相同粗糙度下,磨削加工的摩擦系
数比车削加工的摩擦系数大;摩擦系数随着渗层厚度的增大而增大.从减小摩擦系数的角度来考虑,渗硫层并非
越厚越好.
(the multi-asperity sphere-shape model for surface contact between sulphurized layer and unsulphurized
layer is established.in which the height of sphere-shape asperities follows the Gaussian distribution.1he
frictional coeficients of sulphurized layers are analyzed by using plastic flown line theory.1he results show that
the frictional coeficient increases with the load.the frictional coeficient of ground surface is higher than that
of tumed surface in case of the same roughness.1he thicker the sulphuri[ed layer is.the higher the frictional
coeficient is.From the viewpoint of reducing frictional coeficient,the thickness of sulphurized layer should
be smaller.)

说明: 傅立叶变换在图像处理中的重要作用:
(A) 图像增强与图像去噪
绝大部分噪音都是图像的高频分量,通过低通滤波器来滤除高频噪声;边缘也是图像的高频分量,可以通过添加高频分量来增强原始图像的边缘;
(B) 图像分割与边缘检测
提取图像高频分量
(C) 图像特征提取
形状特征:傅里叶描述子
纹理特征:直接通过傅里叶系数来计算纹理特征
其他特征:将提取的特征值进行傅里叶变换来使特征具有平移、伸缩、旋转不变性
(D ) 图像压缩
可以直接通过傅里叶系数来压缩数据;常用的离散余弦变换是傅立叶变换的实变换;
(Fourier transform in the important role of image processing:
(A) image enhancement and image denoising
Most of all images of high frequency noise by low pass filter to filter out high frequency noise edge is the image of the high frequency components can be enhanced by adding high frequency components to the edge of the original image
(B) Image segmentation and edge detection
High frequency components extracted image
(C) image feature extraction
Shape features: Fourier descriptors
Texture: directly through the Fourier coefficients to calculate the texture features
Other features: The characteristic value extracted by Fourier transform to the characteristics of translation, scaling, rotation invariance
(D) image compression
Fourier coefficients can be directly compressed data commonly used discrete cosine transform is the Fourier transform of the real transformation
