GIS 4035: Module 6 - Spatial Enchancement

This week's lab assignment was centered on working within ERDAS Imagine and utilizing the Fourier Analysis tools, the Convolution tool, and the Focal Statistics tool (found in ArcMap).  The project required us to work with a Landsat image that has bands running horizontally across.  The tools named above were required in order to minimize the banding to the greatest extent possible without losing too much detail in the image. The assignment was built for us to experiment with the different tools in ERDAS, as well as learn how to use them in getting better results.  

In performing this exercise, I used all types of combinations using the tools previously listed in an attempt to remove the strips in the image.  The image shown below is the result of using the Fourier Transformation Editor tool and the Convolution of a 3x3 Low Pass kernel. I made sure to finish by adjusting the histogram of the image for better visualization.  My results aren't 100% perfect, since the bands are still visible from the left side of the imagery. However, the right side looks pretty good.  If I had more time, I would definitely experiment with the different tools in an attempt to get the final result to balance out.  Overall, I enjoyed this assignment.  It was definitely challenging, but I feel as if I've learned some new things along the way.
