Hi,

I have a general idea however I dont know how to start.

I have large data set of images that each image includes many objects in it (some unusual items that I can find in google) that I dont know what are they.

I would like Matlab to categorize the objects from the images and then once they are categorized I will classify them and use the classified images to train the network for future images.

Any suggestions would be appriciated.

I understood that there is an ootion to perform a classification even without knowing whats in the image by just finding equal features between the objects in the image where the features are pretty general as color,shape.

Then, I will go on ech group that it classified and determine what each group is.

You can seperate objects by color or shape, true. For example you could use https://de.mathworks.com/help/images/ref/imfindcircles.html to find circles (like coins) and extract them. If you know the general shapes and/or colors your objects have then you can use the simple image processing variants to extract them.

Those links might help you with that task:
