Neville D Posted August 22, 2007 Report Share Posted August 22, 2007 QUOTE(ashwink27 @ Aug 21 2007, 06:55 AM) what is the difference (advantages) between vision developement module 8.0 &vision developement module 8.5. Look at the release notes for the two products on the NI site. But off the top of my head, new things in 8.5: 1 New edge finding algorithm 2 New straight edge finding algorithm using Hough technique 3 Support for recognizing 2-D bar codes 4 Vision Assistant Express VI 5 Ability to write images to strings in memory (i.e. convert an image to a jpeg/bmp/png string) All submodules of the NI Vision 8.2.1 Development Module have the following new features: · Support for LabVIEW 8.2.1. · Support for Microsoft Windows Vista. · Golden Template Comparison—Functions for comparing images to a golden template reference image. · Data Matrix—Enhancements in speed and accuracy and functions that output the ISO 16022 (AIM) grade for a given Data Matrix barcode. · Optical Character Verification—Functions for verifying the accuracy of characters within an image. For each character, the algorithm compares the character from the image with the reference character, and outputs a score based on the comparison. · Geometric Matching—Enhancements in speed and accuracy, support for searching for multiple templates within a single target image, and searching for templates within a calibrated image. · Shape Detection—Functions for detecting rectangles, lines, ellipses, and circles within an image. · Watershed Transform—Computes the watershed transform on an image. Refer to the NI Vision Concepts Manual for more information about watershed transform. · Local Adaptive Threshold—Thresholds an image into a binary image based on the specified local adaptive thresholding method (e.g. Niblack, Background Correction). · JPEG2000 File I/O—Support for reading and writing JPEG2000 files. Vision Assistant 8.2.1 includes the following additions: · GigE Vision Camera support—Allows users to acquire images from GigE Vision cameras. · Annulus ROI—Added support for the annulus ROI tool in the OCR/OCV step. · Run LabVIEW VI Step—Allows users to call custom LabVIEW VIs from within Vision Assistant scripts. · Image Overlay step—Overlay figures, text, and bitmaps onto an image without destroying the image data. · Image Annotation—Save data with an image file. · 64-bit RGB images—Added support for 64-bit RGB images. Neville. In summary, it is worth upgrading. Link to comment
