Sapera Essential, a machine vision software tool kit that bundles board-level acquisition and control with advanced image processing capability, has been launched by the Dalsa Coreco Div. of Dalsa Corp. It includes a suite of software libraries for image acquisition, display and control, and image processing functions. The image processing libraries include functions for morphology and filters as well as geometric, measurement, segmentation and point-to-point operations, with subpixel accuracy. The geometric search tool uses edge- or area-based techniques, in addition to blob analysis and 1- and 2-D bar-code capability.
