Welcome to Geoff's Webpage
This mostly software I have written. It all comes with no guarantee whatever, but it did work at some time!
For my retirement present I was given a weather station. The readings taken in my garden for the past few years are on the website of my local village.
Another retirement project was scanning all my old colour slides and it turned out that many of the colours had deteriorated over the years. After spending a whole wet afternoon trying to improve them with image processing software it seemed that the best result was using the 'AUTO' button. Since I used to work on image processing (but not this sort) I was sure I could do better than an 'AUTO' button. The result is:
|Deteriorated Original||Restored using my algorithm|
Software for restoring faded photographs. There are plug-ins for the free image processing package GIMP and stand-alone Python programs. The process is automatic and requires no decisions by the user. There is even an android version that will run on a tablet or phone. This version is very slow but could be used to restore a particularly cherished old photo. You can even continue the development work on GitHub
EDSAC2 was an early digital computer, the successor to the EDSAC which is being reconstructed at the National Museum of Computing.. This emulator, written in Python, has a control panel where you can load "paper tapes" into tape readers and operate the switches. There are sample programs including one to compute π to 1000 figures. There is even an Android version. I hope that somewhere in the world a kid will be inspired to learn about computing in the dark ages.
