Removing noise from the image
I guess i have posted this earlier.
I have number of images in a folder. I have to crop those images(without using manual cropping). Now I have changed the images to binary images so that I can perform automatic cropping. Now, when I converted the images to their binary form, I am getting some noise which is preventing me from performing the cropping step. How can I remove the noise from each images? Please Help.
Example:-
I have this original image:-
![](/matlabcentral/answers/uploaded_files/74567/2.jpg)
I have converted the above image image to its binary form for cropping.
![](/matlabcentral/answers/uploaded_files/74569/001bin.jpg)
Now I found that there is a noise present at the bottom left corner of the binary image. How can I remove the noise such that the black colour of noise becomes white in colour.Please help.!
Also, since I have different images in my folder, the shape of the noise portion is also different in different images.How can I remove such noises from those images as well.??? Thanx in advance
