![]() ![]() Then you need to specify diff command for images like this (in git config file): Īs well I have created diff-image alias: ĭiff-image = "!f() f" This can be done in root but then specify this in your root git config file like this: gitattributes files like this: *.jpeg diff=image So first you need to set supported image types in. git-diff-image was my inspiration to write minimal and faster image diffing tool. ![]() I have spent a little bit too much time on this so I think it is worth to share my experience. OK, obviously it wouldn't look like that, but I think the last image outlines my purpose here. Maybe the output would look something like this on the more recent (2015) photo. It would be really neat if I could run some process that would highlight the areas that have changed dramatically, such that the new houses, in this case, would be easily identifiable. Here's an example of two satellite photos, the first taken in May 2013, the other taken in January 2015. I know satellite photos can vary greatly due to weather, photo exposure variations, seasonal changes, etcetera so my plan is to run some photoshop filters on satellite photos to try and normalize the imagery, then run some kind of "diff" process to highlight where changes have occurred. Currently, I'm doing it manually which is very slow. One thing thats interesting is you can determine new construction. In Google Earth, you can roll back the clock on satellite imagery, for whatever reason, and determine what has changed over the years. I'm trying to figure out a way to more rapidly determine where new construction is happening by comparing annual satellite imagery. ![]()
