- 将一幅512×512的原始灰度图像，采用3×3的平均窗口对它作滤波运算（原图像外围的像素的灰度值视为128）；对滤波后图像隔行、隔列丢弃一半像素形成一幅256×256的小图像；对此小图像分别采用最邻近内插、双线性内插的方法将它放大为512×512的大图像。对照原图像，计算两种放大图像各自的PSNR。-A grayscale original image of 512 × 512, using a 3 × 3 window average (gradation values R
High-Frequency-Emphasis-Filtering
- 此代码是关于高频强调滤波。利用高通滤波器削弱傅里叶变换的低频而保持高频相对不变点，这样会突出图像的边缘和细节，使得图像边缘更加清晰。但是由于高通滤波器偏离了直流分分量，从而把图像的平均值降低到了0,。一种补偿方法是给高通滤波器加上一个偏移量。通过算法达到目的。-High-Frequency Emphasis Filtering.High-pass filers zero out the DC term (the value at the center of a high-pass filter

Gaussian
- 高斯滤波是一种线性平滑滤波，适用于消除高斯噪声，广泛应用于图像处理的减噪过程。通俗的讲，高斯滤波就是对整幅图像进行加权平均的过程，每一个像素点的值，都由其本身和邻域内的其他像素值经过加权平均后得到。高斯滤波的具体操作是：用一个模板（或称卷积、掩模）扫描图像中的每一个像素，用模板确定的邻域内像素的加权平均灰度值去替代模板中心像素点的值。-Gaussian smoothing filter is a linear filter for the elimination of Gaussian nois
