Introducing the Myriax AM100 aquatic stereo-video measurement system

Posted on Friday, 4 December 2009 | Permalink

Myriax is proud to introduce its popular AM100 aquatic stereo-video measurement system to the scientific research community.

Developed by AQ1 Systems - Myriax Software's sister company which specializes in optical and acoustic sensor systems in aquaculture - the AM100 is well established in the aquaculture industry and is now being adopted by fisheries researchers.

Features and benefits of the AM100

Rapid, non-invasive identification, measurement and counting of any aquatic organism via two super-high-resolution digital GigE video cameras. Images are recorded onto a ruggedized laptop through CAT-5 cable and processed using the AM100 measurement software.
Flexible sizing of objects via the creation of either single or multiple point-to-point measurements. These measurements can be either compared directly or used to model additional morphometric variables such as mass or surface area.
Count objects moving past a fixed point; great for mobile organisms or in ecological time-related density analysis.
Achieve unsurpassed measurement accuracy of 1-2% of measured length up to 8 m from the cameras.
Tailor the system to your needs. Discuss your specific hardware requirements with our engineers, or use the AM100 software in concert with your existing stereo-camera setup.

Applications

The AM100 incorporates world-leading stereo-camera measurement technology in use by aquatic researchers around the world. These include:

While the AM100 was originally developed to help regulatory authorities assess the biomass of Bluefin tuna being transferred into tuna farms, the system is now gaining popularity in a variety of aquatic research projects. These include studies of benthic flora assemblages and studies for fish species identification, abundance and sizes on artificial reefs.

Baited-camera studies and analysis of fish around FADs would be natural extensions for this cutting-edge system.

Eonfusion Update: v2.0 Release

Posted on Tuesday, 20 October 2009 | Permalink

Version 2.0 of Eonfusion was released earlier this month. Amongst the many new features, it contains:

The Add-in development environment (an Application Programming Interface, or API) that allows any user to write operators, data sources and data writers. The API uses the C# programming language and is included with every Eonfusion license. User-developed “add-ins” can be shared with any other Eonfusion user.
Reprojection and general manipulation of raster geometry. This was available for vector data in earlier versions and is now extended to raster data.
A free-viewer mode that allows somebody without an Eonfusion license to explore your Eonfusion scenes.
Support for 3D models in COLLADA/DAE and OBJ formats. Adding 3D models to scenes can greatly increase the communicative power of data visualization.
A transparency option for all visualizers, which adds further visual richness to Eonfusion’s scene environment.
New operators that link neighboring vertices or raster cells together, enabling a huge range of spatial and proximity-based analyses.

Eonfusion V2.0 takes the vision of Eonfusion as a general purpose analysis and visualization tool to a new level of functionality and usability.

Our September newsletter also contained several items that might be of interest. To browse through it and other recent Eonfusion newsletters, go to the Eonfusion Newsletter Archive.

What's new in version 4.80?

Posted on Wednesday, 14 October 2009 | Permalink

Over the past few months, we have been working steadily towards the release of Echoview version 4.80. The full release is now available to download.

> General enhancements
> Variables & Geometry window enhancements
> COM scripting enhancements
> Tweaks and other changes

General enhancements

Automated region classification
You can now automatically apply region classes to regions using rules based on a region's analysis results (attributes). The new Classification tab on the EV File Properties dialog allows you to create and edit the rules that are evaluated in order to assign classes. Classification can be done automatically after schools detection or manually for a specific region or regions within a selection on an echogram, as well as via the Region Manager.

Above is a screenshot of the EV File Properties dialog box, showing two rules that will apply two region classes. One of these is selected and its conditions are editable in the lower list box.

Hydroacoustics User Forum window
Echoview now contains a new dockable window that shows the most recent posts on the new Hydroacoustics User Forum.

Removal of 500 virtual variable limit
You can now have as many virtual variables in an EV file as you want (we've seen some very large data flows!).

Save as Template
You can now save a copy of your EV file as a template or live viewing template easily via new menu commands on the File menu.

TVG curve available on the ping graph for Sv variables
On S_v echograms, you can now show a TVG Curve on your ping graph using the Shortcut menu. This is useful for faster and more visual S_v background noise estimation.

Variables & Geometry window enhancements

Copy and paste virtual variables, virtual lines and editable lines
This is a long-standing user request! You can now copy and paste items on the Variables & Geometry window. Currently, you can copy and paste virtual variables, virtual lines and editable lines. Objects retain their relationships when they are copied together, and combined with drag and drop of operands (below) this allows very easy duplication of portions of your dataflow within the one EV file, or from one EV file to another!

Copying three selected virtual variables

Drag and drop input operands
The input operands for virtual variables and virtual lines can now be set directly on the Variables & Geometry view. A small node appears when your mouse hovers over an object, and it can be dragged with the mouse to create a new arrow that you can drop onto another object on the view. Objects highlight and dim depending on whether the dragged object is a suitable potential operand. You can either drop the arrow straight on an object, or drop it on an existing input operand’s arrow to replace that specific operand.

Drag and drop to replace a virtual variable's input operand in the Variables & Geometry window

This is also useful when pasting virtual variables or lines, as you can easily hook up complex sets of variables and lines after pasting them into an EV file.

Drag tabs to reorder
You can now drag and drop the tabs at the bottom of the Variables & Geometry window to reorder your views.

COM scripting enhancements

Support for the “Inherit calibration settings from” settings on the Calibration page of the Variable Properties dialog box for virtual variables
Support for shifting regions in depth or time
Support for pre-reading data files – handy for generating EVI files for large quantities of data
Support for editable lines and picking lines, including line pick properties
Support for filesets’ time offset property

These enhancements will help you automate your data processing.

Plus many more other tweaks and useful changes

Line usage information able to be shown on the Variables & Geometry window
A keyboard shortcut to create a marker region at the last ping without having to select the data (especially useful when live viewing)
The tape measure tool’s displayed measurement should stay away from the feature you are measuring
And much more...

Download Echoview 4.80 now!

As always, in version 4.80 we have tried to select a balance of enhancements that will have maximum usefulness across our broad and diverse user group. If there are any new features here that make a real difference for you, we'd love to hear about it! Likewise, if there are features that we don't have and that you'd like to see implemented, or if you would like to know more about the new features, please contact Echoview support.

We hope you enjoy this new release!

Echoview training course wrap-up: Poland, September 2009

Posted on Thursday, 8 October 2009 | Permalink

Briony Hutton and Patrick Schneider ran a 3-day Echoview training course in Gdynia, Poland in early September. The class was attended by 9 students from Poland, Latvia, Sweden and Germany with a wide range of skills and experience in acoustics.

Following the recent release of the Echoview technical manual (www.echoview.com/support/echoview-technical-manual), the first half of the course now takes participants through the various exercises in the manual in an immersive blend of presentations and hands-on work. Following this, the course takes a more in-depth look at multifrequency species identification and background noise removal techniques, before going on to explore Echoview’s scripting and 3D-visualization capabilities.

The course wraps up with exploration of example data that students are invited to bring to the course for this purpose, and a brief demonstration of Myriax’s new 4D data-visualization and analysis software package Eonfusion (eonfusion.com).

The Echoview training course is designed to provide value for all, regardless of experience, and can be tailored to suit your specific data analysis requirements. To enquire about training at your location, please see www.echoview.com/products/training-and-consulting.
