Thanks Dr. Jens Koopmann, for appreciation. I hope you enjoyed it.

Hi Premnath

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

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

Ashish,

I like your program. Initially I had problem to get it to run. There is a command called im2double -> I replaced it with double and it worked fine

Thanks for sharing.

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!
