Sapera Essential is at the heart of Sapera Vision Software delivering a suite of image processing and analysis functions. These functions include over 400 image processing primitives, barcode tool, pattern matching tools both area-based and edge-based, OCR, color, blob analysis, measurement and calibration tools for perspective and lens correction.
Sapera Essential also provides seamless support for multi-core CPUs optimization (MCO), supporting a comprehensive library of highly optimized image processing functions and offering flexible controls to harness the full power of multi-core CPUs for complex applications. Existing Sapera applications can run without modification, immediately leveraging faster program execution.
Sapera Essential delivers a full suite of software libraries for image acquisition, display and control and includes an extensive list of image processing functions. The Sapera Essential feature set includes program portability, versatile camera controls, functions for display management and easy-to-use application development wizards. Machine vision applications using Sapera Essential can be developed with C++, C#, and VB.NET on Microsoft Windows® 10/8/7/XP/Vista Business Edition (32/64-bit) platforms. These applications can be developed using either Microsoft Visual Studio or Borland C++ Builder.
Sapera Essential offers two different barcode reading algorithms:
As part of the barcode tool Sapera Essential also offers Print Quality Grading. Grading is used to verify the quality of 1D and 2D marks.
Sapera Essential includes a powerful frame grabber configuration and camera set-up utility plus a suite of image processing tools including a series of highly optimized basic image processing functions, Blob Analysis and Calibration tools.
Sapera Essential's Measurement Tool is a video metrology tool for machine vision inspection applications involving measurement for positioning, identification and guidance. The measurement tool includes an extensive suite of highly optimized functions to facilitate real-world measurements. In addition, the measurement tool features a wide selection of Image Markers using which measurements can be performed. The marker type includes point, line, polyline, arc, circle, spoke, and many more to facilitate multiple simultaneous measurements from one or more selected paths. The highly accurate results are computed to with sub-pixel accuracy. The measurement tool can be combined with Sapera Essential's calibration tool to obtain consistent and accurate real-world measurements.
A highly integrated optical character recognition tool that is scale and contrast invariant, the OCR tool supports both solid and dot matrix fonts and can be trained on user fonts. Its robust recognition technique is optimized for speed and accuracy. The ability of the OCR tool to operate on significantly degraded images makes it ideal for repetitive inspection tasks performed in the pharmaceutical, electronics and semiconductor industries.
Sapera Essential features an advanced color tool for machine vision that delivers speed, accuracy and flexibility to imaging applications that require color inspection. Ideal for sorting, verification and inspection in food, packaging, print, textile and electronics inspection, this powerful tool supports multiple color spaces such as HSI, CIELAB, RGB, and YUV and can perform color classification in native color space. With it's built in support for color calibration, user trainable color classifier, Delat-E measurement and lookup table operations, the Sapera Essential Color tool augments the performance of Sapera Essential image processing and analysis libraries
