## 🧠 Overview

This project provides a complete implementation of a **Hybrid Deep Learning Model** combining **Convolutional Neural Networks (CNN)** and **Bidirectional Long Short-Term Memory (BiLSTM)** for the **detection of landslide-prone areas** from remote sensing imagery. The approach is inspired by the research article:

🖼️ Dataset Description

• Sources: Google Earth and ISRO’s Bhuvan platform
• Categories:
  • Landslide Images
  • Non-Landslide Images
• Image Size: All images are resized to 128x128x3 (RGB)
• Augmentation Techniques:
  • Rotations: 90°, 180°, 270°
  • Horizontal & Vertical Flipping
  • Brightness Adjustments

🧪 Augmentation helps increase generalization and model robustness.

🧱 Model Architecture

🔹 CNN Block (Spatial Feature Extraction)

Layer	Parameters
Conv2D	3×3 filters, 32/64/128
Activation	ReLU
MaxPooling	2×2
Dropout	0.25

🔹 BiLSTM Block (Contextual/Sequential Modeling)

• BiLSTM with 128 hidden units
• Dropout: 0.5
• Learns both forward and backward dependencies of spatial features

🔹 Dense Layers (Classification)

• Dense (64), Activation: ReLU
• Dropout (0.5)
• Dense (1), Activation: Sigmoid

Final output is a binary class: 1 = Landslide, 0 = Non-Landslide

🔢 Technical Workflow

1. Data Preprocessing:

   • Resize images to 128×128
   • Normalize pixel values to [0, 1]
   • Augment training dataset to prevent overfitting

2. Model Training:

   • Optimizer: Adam
   • Loss: Binary Cross-Entropy
   • Batch Size: 32
   • Epochs: 50

3. Evaluation Metrics:

   • Accuracy
   • Precision
   • Recall
   • F1-Score

4. Result Visualization:

   • Confusion Matrix
   • ROC Curve
   • Loss vs Accuracy plots

📈 Results

Metric	Value
Accuracy	96.6%
Precision	94.6%
Recall	96.8%
F1-Score	95.6%

✅ Outperforms standalone CNN and LSTM models in both precision and recall.
