Our Technology

As the need for image based identification moves out of well-controlled stable environments into the world of ever-changing conditions, traditional machine vision technology has often proven inadequate for the job.

The basic WAY-2C software is a unique system for efficient robust color-based identification where the colors and shape of the items of interest and their surroundings may be arbitrarily complex, and/or change quickly. Unlike traditional methods, it uses very rapid machine learning to routinely produce far more accurate identification than today's widely taught, but outdated, color machine vision methods.

Unlike neural network based methods, WAY-2C does not need to be fully retrained every time an item in the identification set is added, removed, or otherwise changed. Items in the set may be easily relearned, added, removed, and/or temporarily disabled even during production runs.

In spite of its power, WAY-2C-based applications usually require no special operator skills for rapid, efficient training and reliable operation.

Multispectral and hyperspectral imaging systems are characterized by the ability to capture very large amounts of data for analysis. Often, when the purpose is identification, this data can be orders of magnitude more than is necessary to reliably differentiate the specific classes of interest. Our new method, which we refer to as "Relevance Spectroscopy", described in detail in US Patent 8,918,347, addresses this problem in a straighforward, deterministic manner. Once the classes of interest and their training regions have been specified, the method searches the entire data set to find an optimum subset to differentiate the classes. For typical spectral images, the resulting subset comes from three or fewer spectral bands, is one or more orders of magnitude smaller than the original data set, and determination requires a couple of minutes on a modest PC. Color images constructed from the subset are ready for any manual or machine interpretation.
