Introduction

KSAI-ToolKits

KSAI-Toolkits is a toolkit from AI group of Kingsoft Office Corporation. The inference engine is KSAI-Lite (derived from TensorFlow Lite). The toolkit supports OCR function on multiple OS platforms, including Windows, Linux x86_64, and Linux ARM, at the time of initial release. With time, we plan to add support for more functionalities in the future.

Quick Start

1. Environment setup

Requirement on different OS platforms
OS
  • Linux: ubuntu 16.04
  • Windows: windows 10
CMake

The CMake version: 3.16+

Compiler:
  • Linux: GCC 5.4+
  • Windows: Visual Studio 2019

2. Clone this repository

git clone https://github.com/kingsoft-wps/KSAI-Toolkits.git

3. Setup 3rd party libraries

The downloaded package mainly contains:

  • opencv lib and the header files
  • KSAI-Lite lib and the header files
  • Clipper source code

4. Download models and test data

5. Build the project

the build scripts are in tools folder

  • build script on windows is build_windows.bat
build_windows.bat
  • build script on linux x86 is build_linux.sh
./build_linux.sh
  • build script on arm is build_aarch64.sh
./build_aarch64.sh
  • build script on mips64 is build_mips64.sh
./build_mips64.sh

6. Run the test program

Once the compilation is sucessfully finished, look for the executable file KSAI_Toolkits_demo in /output/$platform$/bin/ folder. You can execute it with the following command line paremeters:

./output/linux/bin/KSAI_Toolkits_demo data/OCR/model/db_171_varied.tflite data/OCR/model/cls_best.tflite data/OCR/model/mv3_345000.tflite data/OCR/dictionary/char_6599.txt data/OCR/input/test.jpg

The output of the program should be:
