MosaicViewer

What is MosaicViewer?

MosaicViewer is a software that allows you to visualize large-scale photomosaics of the ocean floor.

If you want to use MosaicViewer to build a photo-mosaic you should first generate a GMML file using the following Matlab code: (download the code either in rar or zip compression).

This page includes both the viewer software, and a set of Matlab files to generate a GMML file.

What is a GMML file?

It is an ASCII file that describes a mosaic using XML.

MosaicViewer needs a GMML file to generate a new mosaic (mosaics have the ".zxf" extension).

What do you need to generate a GMML file?

You will need a navigation file, including:


• the image names

• their UTM coordinates

• the altitude (distance from the camera to the ocean floor)

• yaw of the vehicle

• (optionally) roll and pitch of the vehicle

Download MosaicViewer

The Windows XP executable of the viewer software can be downloaded from one of the following links: MosaicViewer.rar (2.1 Mb), MosaicViewer.zip (2.6 Mb) or MosaicViewer.exe (5.5 Mb)

To uncompress the files, you will need either WinRAR or a compatible uncompressor (e.g. ZipGenius freeware).

In order to learn how to use MosaicViewer, you can shortly look at the Getting Started manual

The Linux binaries of the viewer software can be downloaded from one of the following links: mosaicviewer.rar (3.5 Mb), mosaicviewer.zip (4.5 Mb)

The Vista version of MosaicViewer can be downloaded from one of the following links: mosaicviewer.rar (2 Mb), mosaicviewer.zip (2.6 Mb) or mosaicviewer.exe (5.4 Mb)
(Note that WinXP binaries do not run under Vista, but the Vista version of the viewer can also be executed under WinXP).

The MacOS-X version of MosaicViewer is under development. A beta version (8Mb) is available.

Sample data for MosaicViewer

You can play with MosaicViewer by using the file gmml_sample.zip to build your first photo-mosaic. Later you will be able to build your own GMMLs.

Download Matlab code to generate a GMML from your navigation data

An example on how to generate a navigation file, and how to use the Matlab functions to create a GMML file can be found here: navfile2mosaic_sample.rar (7.7 Mb), navfile2mosaic_sample.zip (7.7 Mb).

Mosaics from the LUSTRE'96 cruise (by WHOI)

Data is available at the Marine Geoscience Data System, including:


• Original images from the LUSTRE'96 cruise

• A photo-mosaic with all images

• A photo-mosaic with images that show at ~5% overlap
