Remove Noise from Image
显示 更早的评论
I have this RGB image.
I cropped the image into 4 equal size and then When I convert these images to binary images using im2bw. I get noisy image.
I have applied different filters but none of them worked. Can anyone suggest which filter or pre-processing technique should I use?

Try using a tophat or bottomhat filter, imtophat() or imbothat(). Or else use adapthisteq().

to add to what he has said, try to convert your RGB to LAB format, then do it on the L layer, then convert back to RGB. BTW, were you able to get good result without cropping the image?
