Hi Premnath

PSNR increase has the visual quality of image increases. So there isn't any problem.

14 Mar 2014 Noise Level Estimation from a Single Image It can precisely estimate noise level from a single image. Author: Masayuki Tanaka

Hi Masayuki

Yeah I saw that code but I've tried to get it done by toeplitz matrix only for Directional Derivative operator to calculate threshold and results are coming satisfactorily but takes time longer as compared to yours code.

Once it seems to be final I'll be uploading it.

Thanks for your reply....

AS mentioned in your paper at section III, equation no. 7, where by Dh and Dv are toeplitz matrix of N^2XN^2 but that not the case. For default patch size of 7 it should return 49X49 its return 35X49.

What the reason for this...

Thanks

Hello Masayuki Tanaka

Could you please mention some details about the function

T = my_convmtx2(H, m, n)

And if not possible here in, please refer me to some pointer

Thanks

What about the beta value? Why you have not included in xls field. And also the MSE of filtered image is greater than that of Noisy Image and the SNR & PSNR of the filtered image is lesser than that of Noisy Image.

hie...i am a new user of matlab and am stuck with the part [FilePath PathStr FileName Ext Index] = GetFilePath();

can anyone please explain how to read the input image in this program with an example.....Thanx!

Hi Ashish, many thanks for uploading. Please add some references. I also need enthalpy data of another solution e.g. MgCl2.

Ain't sure why ain't able to rotate EARTH and MOON on its own axis as mentioned on line 182 and 193...
Please any one can help me on it...
