    Long time ago, I did sth similar, i.e. made a screenshot every few seconds, with the purpose to automatically extract information from it, e.g. how long I was using some app.

    I wrote a PNG DB to split PNG images into many blocks and have each block stored in a DB. If there are several equal blocks, it is only stored once. Via a hash table, the lookup for such blocks is made fast. With this PNG DB, I have a compression rate of about 400-500%. https://github.com/albertz/png-db

    Some of the scripts I used to analyze the screenshots are here, but in the end, it was not really so successful and reliable: https://github.com/albertz/screenshooting

    In the end, that lead to another project, where I just was storing that information more directly, i.e. what application was in the foreground, what file was open. https://github.com/albertz/timecapture
