\u2705 Development Steps (By Phase)<\/h2>\n\n\n\n
\n\n\n\n

\ud83d\udd39 STEP 1: Build a High-Accuracy Car Model Recognition AI<\/h3>\n\n\n\n
    \n
  1. Collect car image data (with a focus on Japanese vehicles)<\/li>\n\n\n\n
  2. Preprocess images and train classification models such as ResNet or YOLO<\/li>\n\n\n\n
  3. Evaluate accuracy and analyze common misclassification patterns<\/li>\n\n\n\n
  4. Visualize decision regions using tools like Grad-CAM to improve interpretability<\/li>\n<\/ol>\n\n\n\n
    \n\n\n\n

    \ud83d\udd39 STEP 2: Establish a Method for Retrieving Price Data<\/h3>\n\n\n\n
      \n
    1. Gather information on new and used car prices via web scraping or public APIs (e.g., CarSensor, Goo-net)<\/li>\n\n\n\n
    2. Create a mapping system that links car model names to pricing data<\/li>\n\n\n\n
    3. Account for variations in price depending on year and trim level; for the MVP, use representative or average prices<\/li>\n<\/ol>\n\n\n\n
      \n\n\n\n

      \ud83d\udd39 STEP 3: Build a Minimum Viable Product (PoC) with Smartphone Camera Input<\/h3>\n\n\n\n
        \n
      1. Capture a car image using a smartphone \u2192 upload the image or send it via API<\/li>\n\n\n\n
      2. Run car model inference and price estimation on a Python backend<\/li>\n\n\n\n
      3. Return results to the user (can be displayed via a simple web UI)<\/li>\n<\/ol>\n\n\n\n
        \n

        \ud83d\udca1 Streamlit + FastAPI<\/strong> or Flutter + Flask<\/strong> are good tools for this phase<\/p>\n<\/blockquote>\n\n\n\n

        \n\n\n\n

        \ud83d\udd39 STEP 4: Develop a Full-Fledged Mobile App<\/h3>\n\n\n\n
          \n
        1. Build a mobile app with integrated camera functionality (using Flutter or React Native)<\/li>\n\n\n\n
        2. Capture \u2192 send image to inference API \u2192 display results<\/li>\n\n\n\n
        3. Design a user-friendly UI\/UX (e.g., thumbnail images, price tags, \u201cpurchase\u201d button-style display)<\/li>\n\n\n\n
        4. Consider features like login, history tracking, and location tagging<\/li>\n<\/ol>\n\n\n\n
          \n\n\n\n

          \ud83d\udd39 STEP 5: Additional Features & Monetization<\/h3>\n\n\n\n
            \n
          • \ud83d\udcc8 Price history tracking with graphs<\/li>\n\n\n\n
          • \ud83d\udee0 Estimate year\/odometer reading based on visual cues or OCR<\/li>\n\n\n\n
          • \ud83d\udcb0 Monetization via ads or affiliate links to used car listings and dealers<\/li>\n\n\n\n
          • \ud83d\udcca Extend functionality to include popularity, user reviews, fuel efficiency info, etc.<\/li>\n<\/ul>\n\n\n\n
            \n\n\n\n

            \ud83d\udd11 Technical Components Summary<\/h2>\n\n\n\n
            Component<\/th>Technology Used<\/th><\/tr><\/thead>
            Car Recognition AI<\/td>PyTorch \/ YOLOv8 \/ ResNet<\/td><\/tr>
            Price Retrieval<\/td>Web Scraping (Selenium \/ BeautifulSoup) or API<\/td><\/tr>
            Server API<\/td>FastAPI \/ Flask<\/td><\/tr>

            \n\n\n\n

            \ud83d\udca1 First Milestone (MVP Idea)<\/h2>\n\n\n\n
            \n

            \u2705 “Upload a car photo \u2192 Instantly get the car model name and estimated used price” \u2014 all within a simple web app.<\/p>\n<\/blockquote>\n\n\n\n
