I have an image with screws and bolts. Property of this image is that the nut is circular in nature and the screws are kind of rectangular. How can I extract them into separate images. Please advise

Segment your image to get a binary image. Then you can use bwpropfilt(). If you don't know the ranges for the two classes of objects, use regionprops() to determine what they are.
