※ 기존의 Car Demage Detection 성능 향상에서 주제 변경

Introduction

A task to Detect & Recognize the expiration date of groceries

Fig 1. ****The overall architecture of the proposed framework

• Solving the social issue of expiration dates not being displayed in braille (점자)

  • Visually impaired people struggle with not having a way to know the expiration dates of products
  • Existing assistive tools for visually impaired people, such as Detection to TTS tools, recognize all text, not just expiration dates, and have a low recognition rate for expiration dates
  • Previous expiration date recognition research:
    • Only considers situations where expiration dates are horizontally placed
    • Specific date format for expiration dates
    • Has a low recognition rate

  : The goal is to detect and recognize expiration dates on groceries from various angles

• Managing the expiration date of groceries through automatic recognition of expiration dates

  • By capturing images of groceries and automatically storing their expiration dates, it will be possible to manage the expiration dates of groceries effectively
