Release note

Beta release

1. Open source the NN Framework to facilitate users to better understand the internal operations of NNF. In the next version, we will distinguish between official and customized partitions, making it easier for users to add their own models or copy an official model to a customized partition for customized modifications. In future versions, we will consider providing a more user-friendly and convenient way to port the code generated by ACUITY TOOL to NNF.

2. Optimize the pipeline dataflow. Optimized some link matching and data flow transmission processes in the pipeline flow, making the data flow path more convenient and the system running smoother.

3. Optimize model plugin. Crop the directory structure related to the model, merge the content related to the model, and make the structure more compact and clear.

4. Add some NN modules.

   1. Optical character recognition.

      • In the OCR section, we optimized the optical processing, tilt processing, and flip detection of the collected images, greatly improving the accuracy of character recognition.

   2. Age recognition.

      • Classify the identified individuals into 8 age groups.

   3. Face det and Age recognition.

      • Combining facial detection module to classify people into 8 age groups.

   4. Yolov8 Detection.

      • Mainly used for object detection tasks, it can quickly detect 80 different targets and achieve fast and accurate image analysis.

5. Add command for model list. You can list the currently supported models and serial connection methods of the system through commands. In future versions, model related information will be dynamically listed based on the actual situation inside the code.

6. Regarding the user interface, maintain compatibility and consistency with the alpha version.

7. Adjust the internal structure of NNF and output the initial version of open-source code.

8. Optimize the system to make it more robust, and after long-term testing, the system is stable.

Alpha release

1. The basic struct of the NN framework. Intended to facilitate users to quickly get started with C3V NN projects, and to use this framework to easily build complex multi-model comprehensive applications. At present, it mainly includes model building and NN application function combination, message passing and log management functions, and other functions will continue to be improved according to the goal in the future.

2. Serialization mechanism, achieving serial links between output and input of multiple models, the concept of a pipeline is similar to the derectshow.

3. Message mechanism to achieve real-time transmission of output results or status information within the system.

4. Provide various forms of sample DEMOs.

   1. From a system perspective, provide sample codes in the form of single model and multiple model collaborations.

   2. From a functional perspective, provide official examples such as yolov5, yolov5&person attr, face detection, etc. for user reference.

5. A complete log management mechanism can achieve multi-level control such as TIMING, FATAL, ERROR, WARN, INFO, DEBUG, VERB, etc. The release version defaults to the ERROR level. This mechanism has a standardized log flag that can be refined to module control, supports custom tags, millisecond timestamps, and can be directly saved to a file, supporting subsequent chart analysis.

6. A standardized make&release mechanism provides standard compilation scripts without the need for users to worry. A single command completes all compilation tasks, and the generated sample app and libs are standardized to the default specified directory, making it convenient for users to access.

7. The source code is not currently open source for this release, libs, header files and a sample app will be provided for this release. Customers can use our sample demos or add them to their own applications to achieve predetermined functions.

   1. At the same time, we will produce an SOP that provides a detailed description of what is necessary to easily add a multi model combination NN application.

   2. We will open source the code during the Beta release, and at that time, the NN framework will have a better data transmission mechanism, a more convenient process for adding models, and the addition of official models.
