Description: Briefly with the following code I will try to embed the MSB of the baboon image into the picture of Lena by exploiting the LSB embedding technique. We will try also to add an WGN (white gaussian noise) to the image then after these operations we will write to file the results. The code is heavily commented, so I think that further explanations are not needed.Recover Platform: |

Description: 图像处理作业 用matlab显示直方图 累积分布函数 加高斯噪声 再用平滑降噪 都是自己编的程序-Given the test image "Lenna" 256*256 with 256 gray levels, do the following:
1) Using MATLAB display the test image.
2) Display the intensity histogram of the test image.
3) Using the image histogram and cumulative distribution function, locate the intensity value such that 20 of the output pixels are saturated to 0.
4) Add Gaussian noise(mean 2, variance 4) to the test image and display the noisy image.
5) Apply smoothing and median filtering to the noisy image and display the results.

Description: matlab code
Proposed Algorithm
1. Consider the image to be resized to N x N (Original image I having N value of pixel)
2. Image is to be changed into gray and double for 2-D image.
3. Add noise to image using gaussian white filter.
4. Image de-noising using Isotropic Total variation filter can provide much better result than the LLSURE filter.
Where is the adjoint operator of with respect to standard inner product.
5. The corresponding Euler-Lagrange equation
6. Calculate Mean Square Error and Peak Signal Noise Ratio for de-noise image.
