How can we extract objects from a greyscale image?
显示 更早的评论
So, i got a grayscale image of a box, which contains some objects.. I need to identify if/ not the box is empty or not....
I tried using the otsu thresholding, but doesn't work properly. is it possible to convert all the other parts to black except the image of interest?

How do you know which part is of interest before you have done the thresholding ?

I would recommend background subtraction, if you can get a picture of the empty bucket, especially if everything is taken from a fixed viewpoint (if the viewpoint is not fixed then you might need to do image registration before doing the subtraction.)

What about bwareaopen()
I = imread('example_filled2.jpg');
I1 = I < 40;
I2 = bwareaopen(I1,3e3);
imshow(I2)
What i've got
