  RaSpect Intelligence Inspection Limited

  Job Summary.

  • Object Detection Related.
    • Text Detection. Implemented text detection (EAST) to facilitate signboard defect classification.
    • Crack Detection. Help implement detection model for crack and spalling.
    • Rust Detection. Implemented two solutions: (i) Text removal -> classifcation pipeline; and (ii) direct object detection model using faster rcnn.
  • Image Generation/Inpainting.
    • DefectGAN. Implemented image-generation model following this paper that generate synthetic data on cracks and spallings for training defect detection models on facades.
    • Text Removal. Experimented with existing algorithms like various GAN or image-inpainting method in pytorch. Finally I follow this paper to obtain a text eraser with satisfactory performance.
      For an example of failed model, we refer the results to here.
  • Web or Hardware Related.
    • Maintain React Next project.
    • Data scrapping for house transactions records.
    • Automation on tracking latest rtk-data from official geodetic website and data-processing pipeline.
    • Work with a local grpc based service in Python to interact with a compiled binary (.exe), messed with multi-threading stuff.
