Gaussian noise and Gaussian filter implementation using Matlab

[@rd1abrar924]

The explanation was quite lucid. Thank you!

[@LuhitDas6]

THANK YOU...... ITS HELPING ME A LOT NOW.... :)

[@medjdamima8492]

have you executed the code please ?

[@rd1abrar924]

The screencast disappears at 0:46. It's not much of a problem tho, the code can be seen later.

[@SushrutRajkuwar]

Thanks maam... Helps a lot !!!

Hi i have a question: if we have the frequency spectrum of a signal.. and we identify there the broadband, how can i build the gaussian function with those values? thanks in advance

[@mohammadmaaz31]

u made my day that's what i was looking for

[@salihsahin7585]

thank you rashi :) It has been a very useful work

[@youngresearcher.]

imfilter should be used if you have the IPT and are working with images. Personally, I only use conv2 since I hate the conversion to uint8 and often want (at least temporary) values above 255.

[@abhij2905]

Video helped me alot. I wanted to know how to dind the wiener coefficients . Is it possible to get images per iteration ? As in how the image noise gets reduced using the wiener function ..

[@handokochi5842]

thank you, you helped me so much. :)

[@heartbreakkidmihir]

why did u use conv2 ? cant we use filter2 ?
what is the difference between conv2 and filter2 ?

[@brother_hasnain]

Mam i am getting an error on applying weiner2 filter.
ERROR -> Undefined function or variable 'weiner2'.

[@devilboii96]

How do I do it manually by using for loops?

[@LofiLove049]

can you make a video on making guided filter. if yes then plz reply me.

[@alexandernaif]

the output image is just as a ref image, so what is histsp good for ?

hi rashi mam, iam doing reaseach on image processing so i want to know about local mean estimator using lms algorithm so in this topic i want to find mean of (noise+image) after that i want to find output can u help me mam i have paper with me name is "two dimensional local mean estimator adaptive filter using lms algorithm

[@sunilkale7420]

very useful session mam thank u so much.
how to apply it for gray scale image

[@siyadhams3047]

Great Thanks!

[@swapnilshrivastava2770]

mam how can I save video after adding noise?

[@ravikiranc7659]

Can you develop gaussian high pass filter

[@sarathchandraprasadveluri1574]

Need image sharpening algorithm for 5×5 window or 7×7 window in matlab..please upload.

[@lutfifebrianditabasuki2707]

thanks you

[@sunilkale7420]

how can i use it for matched filter expression
D0=1.5
Dx=((u-(N/2))^2+(v-(N/2))^2)^0.5;
D=Dx*Dx; % FOR SQUARE
%if abs(u)

[@medjdamima8492]

i need this code please
