  1. /ˈpuː.dəl/ プードル Platform, train the DL Model with Labeled Data.

    Use the trained DL Model detect and predict for the unlabeled image data
  2. Content proof In-line inspection Verification Final check Pre-press proof Off-line

    inspection Defect classification Design Printing Verification Packaging
  3. Defect classification Verification Printing Packaging Not OK / Failed

  4. Product Lineup • POODL Platform • Cloud version • On-premise

    version • Developer Utilities • POODL Client • POODL CLI • POODL SDK • API documentation • Developer Support
  5. Basic Functions • Storage • Upload images and store them

    on a per-dataset basis • Allows you to split, merge, and edit datasets • Annotation • A simple user interface that allows you to focus on classification tasks • Ability to work securely with authority functions • Data Augmentation • Amplification of data that does not loss the characteristics of the inspection image • Learning • Process to train model without expertise • Analytical • Analyze the accuracy of a trained model • Download the appropriate learning model • Inference • Install into inspection equipment for fast off-line processing Storage Preprocessing Annotation Training Analytical
  6. Storage Preprocessing Annotation Training Analytical Machine Operator Manager

  7. Data in factory Production run Application / Machine is a

    FACTORY to make trained model Custom-ordered system Algorithm, extracted knowledge in image data
  8. Features Web Application Authority Management Original DL Engine Efficient Annotation

    Scalable File Manager Linkage with External Devices
  9. Web Application • By adopting container technology, the latest application

    can be used in both cloud and on-premises version • the functional unit services are able to flexibly deal with customization requests
  10. Cloud Version • DB separated multi tenant • Scaling computing

    resources against requests • Low-cost deployments Features Web Browser Google Chrome, Firefox Network Cloud: >= 10 Mbps (download, upload) On-premises: >= 100 Mbps RAM >= 4GB Client System Requirements Application Foundation Separation of application and data, multi- tenant with DB division realized reliable data separation and scalability. A社 Computing Resources B社 C社 Authorization Service
  11. On-premises version • Ensuring of security by self-management • Exclusive

    use of computing resources • Capitalization as production equipment • Independent on stability of internet line Features OS Linux (Red Hat Linux Series, Ubuntu etc.) Processing Unit GPU: NVIDIA GPU (CUDA 9.0) RAM >= 16GB Storage HDD (>=2TB), SSD for cache(>=400GB) Additional outer storage for backup Network >= 100 Mbps Application Environment Virtualizing: Docker System Requirements Manager Administrator Operator Machine Image Data knowledge Manage Collaborate through LAN ※ only for distribution in Japan
  12. Authority Management • Automatically share what you work within the

    organization • Account privilege management is limited to administrators only • Controls authority group by group according to roles such as annotation work only, image upload only Organization Manager Group Operator Group Machine Group
  13. Original DL Engine • Original DL Engine “DLC-Titan” based on

    TensorFlowTM • Learning of large-scale data set of several million scale • A network model suitable developed for print quality inspection • Prevent a faulty product from being put on the market by biased numerical optimization method • General-purpose trained model for application to small lot multi-product • It is also possible to any deep learning engine (It may be necessary to develop another API.) ※TensorFlowTM is developed by Google LLC, is an open-source software library for dataflow and differentiable programming across a range of tasks.
  14. Efficient Annotation Tools • By specializing in learning of printed

    inspection images and narrowing down to necessary functions, you can concentrate on image classification work and efficiently perform annotation work. • The progress of work can be checked in real time by the administrator.
  15. Scalable File Manager • Even when editing, copying, and concatenation

    operations of data sets do not excessively consume storage capacity Reference as virtual data Linked Real Object RDB + Strorage Collect / Annotation Preprocess / Augmentation Training Inference / Analyze Light operating experience even if massive images
  16. Linkage with External Devices • Provide API, SDK, CLI for

    direct data communication with existing facilities such as inspection machine. Inspection Machines File Servers Manager PCs ERP Systems
  17. Developer support, Customization • POODL Client • POODL CLI •

    POODL SDK • API documentation We are also developing applications using POODL, implementing SDK into inspection machine, and providing support for linkage with other systems.
