Enhancing an image is more than a process, it's like art by mouse movements. Too quick, it blurs, too slow, it's black, just right, well it's nearly ok. This image is a Landsat 7 which needed work. The original was a stripped thing which is not very pleasing. The results of this exercise are acceptable but could still use a little work, but for the learning of it, well, ok.
It's through ERDAS>raster>Fourier>Fourier Transform Editor, then with the "wedge", next the LowPass (which either worked ok or didn't), next came Convolution filtering 3x3 sharp. Upon all of these, I took the image through a statistics filter with a 4.0 multiplier then adjust the histogram a bit. What a recipe!
Great work on Image Enhancement
