The homework and the project of D.I.P

Quantization and Scaling
- 使用双线性插值对灰度图像进行放缩
- 对输入的灰度图像进行量化
Histogram equalization and Spatial filtering
- 不允许直接调用现成的直方图均衡化接口，对灰度图做直方图均衡化
- 实现一个对灰度图进行空间滤波的函数
Frequency filtering
- 不用现成函数实现傅里叶变换和反变换
- 对灰度图像进行频率域滤波
Image restoration and Color image processing
- 给灰度图像添加噪声并且用各种滤波器进行去噪
- 对彩色图像进行直方图均衡化处理
Image super-resolution
- 计算图像的峰值信噪比PSNR和结构相似性指标 SSIM
- 不用现成函数实现图像的双三次插值
- 根据论文Fast Direct Super-Resolution by Simple 实现图像超分辨
