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.

In summary, it is worth upgrading.
