# About This Release

As of VisionPro Deep Learning 2.1, Cognex brings a couple of brand new features that steer your machine vision journey to the new round of excellence.

### High Detail Quick Mode

High Detail Quick Modes (Red Analyze High Detail Quick, Green Classify High Detail Quick) are new architectural brothers of the High Detail modes (Red Analyze High Detail, Green Classify High Detail) with lightening fast training, much the same strong accuracy and robustness as High Detail modes, and much less parameters that requires to be tuned.

Red Analyze High Detail Quick and Green Classify High Detail Quick offers much faster training speed than Red Analyze High Detail and Green Classify High Detail, respectively, but they holds the slightly lower level of accuracy and robustness to that of High Detail modes.

- Red Analyze High Detail Quick: 2~3X faster training than Red Analyze High Detail with similar level of accuracy, given the default values of Tool Parameters.

- Green Classify High Detail Quick: 3~5X faster training than Green Classify High Detail with slightly lower level of accuracy, given the default values of Tool Parameters.

Plus, its "Quickness" is completed by the effortless, time-saving training which is driven by the very small number of Tool Parameters tuned by hand.

Note: For the details of Red Analyze High Detail Quick, see Red Analyze Tool and Red Analyze Tool – High Detail Quick
Note: For the details of Green Classify High Detail Quick, see Green Classify Tool and Green Classify Tool – High Detail Quick Mode
Note: For how to use Green Classify High Detail Quick and Red Analyze High Detail Quick with API, see Breaking Changes to the API.

### New Parameter Search

Parameter Search has been renovated and become much easier and more handy to determine the best parameter set for training. The improvement was mainly made in its user interface and experience. Due to this change, Parameter Search adopted queryable combo box for parameter selection and easier way of inserting parameter values, easy-to-get and more detailed description of search results, and many other improvements.

Note: See Parameter Search and Use the Parameter Search Utility for more details.

### New Features Summary

- Red Analyze High Detail Quick and Green Classify High Detail Quick

  - Faster than High Detail modes in training

  - Stay solid in task accuracy

  - More convenient with much less Tool Parameters to be tuned by hand.

- Revamped Parameter Search

  - The user interface of Parameter Search has been completely renovated to enhance the usability of the tool.

- Heatmap Overlay on Image Display Area for Green Classify High Detail and Green Classify High Detail Quick

  - For Green Classify High Detail and Green Classify High Detail Quick, the heatmaps are not only visible through View Inspector but directly in Image Display Area by enabling Heatmap checkbox in Image File Information. See Green Classify Tool – Classification Tags and VisionPro Deep Learning Tool GUI for the details.

### Improvements

- Green Classify API Example Codes are updated for getting label information from images (RAPID XML)

- C:\ProgramData\Cognex\VisionPro Deep Learning\2.1\Examples\c++\Example.Training.HDGreen

- C:\ProgramData\Cognex\VisionPro Deep Learning\2.1\Examples\c++\Example.Training.Green

- Improved tool loading speed into Workspace for a Red Analyze tool when it has significantly many detected regions (more than hundreds or thousands of regions) or regions with complex shapes per image.

- Enhanced document contents. See Documentation Updates for the details.

Note:

- The VisionPro and VisionPro Deep Learning software require that a valid Cognex Security Dongle be installed directly to PCs running the software during all phases of operation (programming, processing, training, testing, etc.). Any attempts to temporarily remove, substitute, or share a Cognex Security Dongle may cause your system to operate incorrectly, and may result in the loss of data.

  When VisionPro Deep Learning is configured for the Client/Server functionality, and a computer has been configured as a server, the Cognex Security Dongle must be attached to the server, but the client(s) does not need a Cognex Security Dongle.

- Sample code is included with the VisionPro Deep Learning 2.1 installer. The resources for the sample code (VisionPro Deep Learning 2.1 Sample Code Resource.msi), which include images and workspaces, are available for download from the Cognex Support Site.
- For more information about new API functionality in this release, see the Cognex VisionPro Deep Learning Suite .NET Library and Cognex VisionPro Deep Learning Suite C API help files.

# Introducing Cognex Deep Learning™

- VisionPro Deep Learning is Cognex’s new PC-based deep learning software product. It is the direct successor to VisionPro ViDi™. The first release of VisionPro Deep Learning adds a new “High Detail” mode to the existing ViDi Classifier, which is now known as “Focused” mode. High Detail mode was originally developed as part of the SuaKIT™ product. It provides highly accurate results for a wide range of challenging applications, while Focused mode typically trains and runs faster. In the recent release of VisionPro Deep Learning, a new mode called "High Detail Quick" is added, offering a much faster training speed than High Detail along with all the merits of High Detail mode. Users can switch between modes without relabeling the images. This makes it easy to determine which mode offers the best combination of accuracy & speed for any particular application.

- VisionPro Deep Learning is compatible with VisionPro ViDi, including API, project loading and security dongles.

- SuaKIT users can import SuaKIT classification and segmentation project into VisionPro Deep Learning. They can then take advantage of the other features of Cognex Deep Learning Studio, including the Blue Locate, OCR tools, and tool chaining.
