hi sir, can I know how to use bwareaopen for RGB image. after I convert the rgb image to binary, do I need to put uint8 and [] when displaying the binary images?

hi sir, may I know how to assign the conversion of rgb to binary. for instance,, I've used this coding but the output is all black,why is that:
%%Binary
im=uint(im)
figure;imshow(im,[])
%%remove pxls less than 100
pixels=100;
detectObject=uint8(bwareaopen,pixels)
figure;imahow(detectObject,[])

That doesn't make sense. You don't use bwareaopen for RGB AND binary. You use it just for binary images.
You do not need to cast binary (logical) images to uint8 or use [] in imshow() for binary images.
Try
binaryImage = im < someThresholdValue;
detectObject = bwareaopen(binaryImage, pixels);
imshow(detectObject);

Are you asking us to give advice on your image without showing us your image? How successful do you think we can be in that situation?

bwareaopen() is a function call that you need to apply to your data. You are instead calling it with no parameters, so it would be returning the empty matrix.
