Unsupervised learning from images [closed]

Question

I want to design a model that can detect the different feature in the images, let's consider we have ~100000 images of cows. when I give this images to the model it has to identify different parts of the cow like eyes, feet, udder etc. How can I do this, one way is to label the images and train the model but is there an automatic detection of features from the images.
