Dalsa has advanced the colour capability of its Sapera Essential software for machine vision applications.
Sapera Essential is a cost-effective machine vision software toolkit that combines board-level acquisition and control with advanced image processing capability.
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 colour capability, which can be divided into four main categories: colour conversions, a series of optimised colour space conversion functions supporting RGB, YUV, HSV and LAB formats - split and merge functions are also available for plane-by-plane processing; colour image processing, a set of basic image processing operators such as thresholding, histogram, projections, statistic, clustering and colour reduction; colour calibration, a colour-correction algorithm trained from a standardised colour chart and used to compensate for different lighting conditions; colour classification, a colour classifier trained from a series of colour samples and used to separate colour regions of an image.
Coupled with a blob analyser, it is used to inspect colour images in areas such as food inspection and pharmaceuticals.
Sapera Essential offers you a single API and a comprehensive features set, including: acquisition control; image processing primitives; blob analysis; area and shape-based pattern matching; colour; barcode (linear/1D- and matrix 2D- coded); OCR and lens correction tools.
Fully compliant with Dalsa's Trigger-to-Image reliability framework, the latest version of Sapera Essential now includes support for the Windows 64-bit and .net platforms.
Developers creating code or porting legacy code to 64-bit operation now have access to a complete software development kit (SDK) from Dalsa.
The Color Tool also provides a C++ and .net interface, and is supported under Sapera Architect, a GUI-based image processing prototyping environment.
Support for the .net platform in Sapera Essential allows rapid application development using Microsoft Visual Basic, C# or C++ platforms.
