By defaut the first launch will be in French. To turn into English, click on the bottom FR button, it will toggle into EN. Quit the application, and launch inti_mosaic again. The language ill be in English.
The exe file is in the unzipped directory. It may take a dozen af seconds before the user interface appears. Maybe less at second launch
At launch, windows does not recognize the signature so may display a warning to protect your pc from virus and prevent the program to execute. Trust the program and force windows to execute it anyway.

INTI Mosaic references
This work has been inspired by the ENBLEND program used in Hugin, which is a reference for image mosaic.
ENBLED itself is based on the publication : A Multiresolution Spline With Application to Image Mosaics, PETER J. BURT and EDWARD H. ADELSON, 1983
The algorithm code from Greg Marcil github has been largely adapted to fit automatically multiple images.
