I am unsure what exactly you mean by 'segmented' but if you want to classify an image in ERDAS, you can go directly to menu Classification.
You can choose whether to use Supervised Classification or Unsupervised Classification.
If you have a training sample or ground checking area, that would better to guide you to precise result of classification.
