Maam your video lectures are up to mark thanks for all this stuff,can you please help me to understand fuzzy rule based filtering for impulse noise removal?
why do we need to apply salt and pepper noise to image... if we do not apply any noise ... then what do median filter do ?? and then if how to check that there is any noise in image .. is there any help with median filter to remove noise without applying by ourselves
Hi, the method was effective but there is a small error turning up like Undefined function or method 'conv2' for input arguments of type 'double' and attributes 'full 3d real'. Error in ==> filter2 at 73 y = conv2(hcol, hrow, x, shape); how to deal with it ??
Nehal Kriti we are corrupting the image to show the use of median filter on an image corrupted with S&P. You can try median filter on an image which has S&P kinda noise
hi maam,i had designed Super resolution using adaptive wiener filter now i want to show how adaptive wiener filter is better than median and average filter how to compare show that in same code.thnx
you could try to use imfilter instead. It has more features. Although it may be slower, the function is certainly easy to use. Here is a link to mathworks on the same: in.mathworks.com/matlabcentral/answers/37199-imfilter-and-filter2

amazing video please make such simple videos more regarding matlab. you can simplify any topic

thanks for video. can you help me about red eye detection in matlab

thelearningsquare.in/2014/09/median-filter-remove-salt-pepper-noise/ try the code by copy paste...if it doesn't work get back to me
hey it's showing that page not found
thank you! by the way, are there any techniques of implementing histeq() as a function in either nlfilter() or colfilt() ?
Rather than using nlfilter or colfilter u can try
fun =@(block_struct) histeq(block_struct.data);
b = blockproc(a,[8,8],fun);
rashi agrawal thanks for the heads up!
Very useful thank you!! :)
Thank you, this one worked got the image
how can I use Adaptive noise reduction filter??
mam....why you take tif format image ...why dont jpg or png ??
Mam please give code on SVM classifier for image classification
what if i dont want to use the predefined matlab function medfilt2 or medfilt, what other functions can be used??
Bashiru Otokiti u can use the theory behind to make a function of ur own.,...will try n make it asap
rashi agrawal can you show us how?
Hi, Ms. Why I got an error said error in filter2 :(
why we need to corrupt the noise at the first place? is it necessary to use salt and pepper before median???
reply asap...

This is the error I am having
Error using conv2
N-D arrays are not supported.
Error in filter2 (line 59)
y = conv2(hcol, hrow, x, shape);

mam, can you mail me this word file
need c++ code :(
not understandable
