gomosaic is an mosaic image generator written entirely in Go. In short: It manages an image database and given a query image returns the image composed or "approximated" of images from the database. The methods implemented are mostly based on "On the use of CBIR in image mosaic generation" by Yue Zhang, 2002, University of Alberta. For more information see the Wiki.
The project originate from a Golang introduction course where I was looking for a project for the participants. Over time I became more and more interested and started working on this project.
Orignal image (Kybfelsen by Freiburg, photo by me) transformed into a mosaic with 70x50 tiles:
For more examples check the Wiki's example page.
If you are a developer and want to play around / use this library just run go get -u github.com/FabianWe/gomosaic.
If you just want to use the software please check the release page for downloads. Currently binaries are uploaded for linux and windows with am64, if you need something else please contact me or compile for yourself. You should rename the file to plan gomosaic or gomosaic.exe (instead of for example mosaic mosaicamd64.exe).
For usage instructions see here. Currently it can only run in command line mode, I'm planning to write a GUI though.
There are probably bugs in this software, though it worked fine for "useful" inputs. Please open an issue on github or send an email to fabianwen#posteo.eu (replace # with @).
Implement color coherence vectors as mentioned in Yue Zhang, 2002. Also the same image gets selected again and again for a query image, especially with big areas of nearly the same color. Implement a mechanism that prevents this.
