In this video tutorial you can learn about image processing through ERDAS Imagine 2015 software and specially I will talk on "How to do spatial subset of an satellite image"...
This step is important as to reduce your data volume so that it can help to easy handling of dataset. By doing this subset operation you can work on your area of interest (AOI) or region of interest (ROI) or study area.
As we all know that there are so many methods to this subset operations like subset by AOI, by using Inquire Box, by Shapefile. In this video I have explained all these methods theoretically as well as in the ERDAS software.

In this tutorial I have used LANDSAT-8 satellite image. It is an geo-corrected and atmospherically corrected image acquired from NASA, USGS Earth Explorer website.
