🌸 Saffron Image Processing

A computer vision project to automatically detect saffron flowers in agricultural images using image processing techniques.

---

📌 Overview

This project implements an image analysis pipeline using Python and OpenCV to locate saffron flowers in an image. It utilizes color space conversion (RGB → HSV/HSI), thresholding, and morphological filtering to identify flower regions based on their distinct purple/violet color characteristics.

🔬 Application: A useful tool for smart farming, agricultural monitoring, and AI-based plant detection systems.

🚀 Features

• 🌈 Color Space Conversion: Efficient RGB to HSV/HSI transformation.
• 🎯 Precise Detection: Identifies flowers using color masking thresholds.
• 🧹 Noise Reduction: implementation of morphological operations (Erosion/Dilation).
• 📦 Modular Design: Easy to extend with Machine Learning models.
• 🖼 Visual Output: Generates annotated images with bounding boxes/contours.

🧠 How It Works

1. Input: Load the saffron field image using OpenCV.
2. Preprocessing: Convert the image into HSV color space for better color separation.
3. Masking: Apply lower and upper thresholds to isolate the saffron purple color.
4. Cleaning: Perform morphological operations to remove noise and fill gaps.
5. Output: Mark detected regions (contours/centroids) and save the result.

▶️ Usage

1. Install dependencies

If you have a requirements.txt file:

pip install -r requirements.txt

Or install the libraries manually:

pip install opencv-python numpy matplotlib

2. Run the detector script

Make sure to place your input image in the project directory (e.g., sample_input.jpg) or update the path in the code.

python saffron_detector.py
