DALSA Advances Machine Vision Software Color Capability

WATERLOO, ONTARIO -- DALSA Corporation (TSX: DSA), a global leader in machine vision technology, today announced it has advanced the color capability of its Sapera Essential software for machine vision applications. Sapera Essential (Edition 01/2009) is a cost-effective machine vision software toolkit that bundles board-level acquisition and control with advanced image processing capability. It is intended to deliver the critical functionality needed to design, develop and deploy high-performance machine vision applications, while at the same time significantly lowering deployment costs. This version of Sapera Essential provides support for Windows 64-bit and the .Net interface.

With the introduction of the Sapera Essential Color Tool, the software delivers improved color capability which can be divided into four main categories:

  • Color Conversions: a series of optimized color space conversion functions supporting RGB, YUV, HSV and LAB formats. Split and merge functions are also available for plane-by-plane processing.
  • Color Image Processing: a set of basic image processing operators such as thresholding, histogram, projections, statistics, clustering, and color reduction.
  • Color Calibration: a color correction algorithm trained from a standardized color chart and used to compensate for different lighting conditions.
  • Color Classification: a color classifier trained from a series of color samples and used to separate color regions of an image. Coupled with a blob analyzer it is used to inspect color images in areas like food inspection and pharmaceutical.

Hardware independent, Sapera Essential offers users a single API and a comprehensive feature set, including: acquisition control, image processing primitive, Blob analysis, area and shaped based pattern matching, color, barcode (linear/1D and matrix/2D codes), OCR and lens correction tools with easy-to-use application development and evolution tools.

Fully compliant with DALSA’s Trigger-to-Image Reliability framework, the latest version of Sapera Essential now also includes support for the Windows 64-bit and .NET platforms. Now, developers creating new code or porting legacy code to 64-bit operation have access to a complete software development kit (SDK) from DALSA. The Color Tool also provides both a C++ and .NET interface and is supported under Sapera Architect, a GUI-based image processing prototyping environment. Support for.NET platform within Sapera Essential allows for rapid application development using Microsoft Visual Basic, C# or C++ platforms.

Free Run-Time Licenses
Targeted at machine vision OEMs, the Sapera Essential run-time components are modular in nature and facilitate field installations to meet various performance and price requirements. When bundled with various DALSA image capture and processing hardware, the Sapera Essential run-time license (for the template based pattern finding, shape analysis and lens correction tools) is offered free of charge. In addition, other Sapera Essential image analysis tools such as edge-based pattern find tool, 1D and 2D barcode, OCR and Color tools are offered at competitively priced combinations.

Download Evaluation Copy
An evaluation copy of Sapera Essential for 32-bit and 64-bit is now available for download from the DALSA website.
