|
45 |
+
|
46 |
+
- Convolutional Neural Networks (CNN) for feature extraction
|
47 |
+
- Long Short-Term Memory (LSTM) networks for sequence modeling

48 |
+
- Advanced pattern recognition techniques
|
49 |
+
- Specialized preprocessing for shorthand symbols
|
50 |
+
|
51 |
+
## About Gregg Shorthand
|
52 |
+
|
53 |
+
Gregg shorthand is a system of stenography invented by John Robert Gregg in 1888. It was widely used for:
|
54 |
+
|
55 |
+
- Court reporting
|
56 |
+
- Business correspondence
|
57 |
+
- Note-taking
|
58 |
+
- Administrative documentation
|
59 |
+
|
60 |
+
This model helps digitize historical shorthand documents and assists in stenography education.
|
61 |
+
|

+
|
64 |
+
- **Model Type**: Image-to-Text Recognition
|

### What is Gregg Shorthand?
|
124 |
+
|
125 |
+
Gregg shorthand is a phonetic writing system invented by **John Robert Gregg** in 1888.
|
126 |
+
It was the most popular shorthand system in the English-speaking world for over a century.
|
127 |
+
|
128 |
+
**Key Features:**
|
129 |
+
- **Phonetic**: Based on sounds rather than spelling
|
130 |
+
- **Cursive**: Written in flowing, connected strokes
|
131 |
+
- **Efficient**: Much faster than longhand writing
|
132 |
+
- **Geometric**: Uses circles, curves, and straight lines
|
133 |
+
|
134 |
+
**Historical Uses:**
|
135 |
+
- Court reporting and legal documentation
|
136 |
+
- Business correspondence and meeting minutes
|
137 |
+
- Journalism and news reporting
|
138 |
+
- Personal note-taking and diary writing
|
139 |
+
- Administrative and government records
|
140 |
+
|
141 |
+
**Why Digitize?**
|
142 |
+
- Preserve historical documents
|
143 |
+
- Make archives searchable
|
144 |
+
- Support stenography education
|
145 |
+
- Research historical communications

### Image Guidelines:
|
151 |
+
|
152 |
+
**β
Best Practices:**
|
153 |
+
- Use **high-resolution** images (300+ DPI)
|
154 |
+
- Ensure **good contrast** between ink and paper
|
155 |
+
- Crop images to focus on **shorthand text only**
|
156 |
+
- Keep text **right-side up** and **straight**
|
157 |
+
- Use **well-lit** photos without shadows
|
158 |
+
|
159 |
+
**π± Phone Camera Tips:**
|
160 |
+
- Hold steady and focus clearly
|
161 |
+
- Use good lighting (natural light works best)
|
162 |
+
- Avoid glare and reflections
|
163 |
+
- Fill the frame with the shorthand text
|
164 |
+
- Take multiple shots if needed
|
165 |
+
|
166 |
+
**π Document Scanning:**
|
167 |
+
- Scan at 300 DPI or higher
|
168 |
+
- Use grayscale or color mode
|
169 |
+
- Ensure flat documents without curves
|
170 |
+
- Clean dust and marks if possible
|
171 |
+
|
172 |
+
**βοΈ Confidence Threshold:**
|
173 |
+
- **Low (0.3-0.5)**: Shows more results, including uncertain ones
|
174 |
+
- **Medium (0.5-0.7)**: Balanced accuracy and coverage
|
175 |
+
- **High (0.7-1.0)**: Only high-confidence results

### Model Architecture:
|
181 |
+
|
182 |
+
This recognition system uses:
|
183 |
+
- **Convolutional Neural Networks (CNN)** for visual feature extraction
|
184 |
+
- **Long Short-Term Memory (LSTM)** networks for sequence modeling
|
185 |
+
- **Advanced pattern recognition** algorithms
|
186 |
+
- **Custom preprocessing** optimized for shorthand notation
|
187 |
+
|
188 |
+
### Model Specifications:
|
189 |
+
- **Input Size**: 256Γ256 pixels
|
190 |
+
- **Framework**: PyTorch
|
191 |
+
- **Training Data**: Specialized Gregg shorthand dataset
|
192 |
+
- **Preprocessing**: Grayscale conversion, normalization, noise reduction
|
193 |
+
|
194 |
+
### Performance Notes:
|
195 |
+
- Optimized specifically for Gregg shorthand notation
|
196 |
+
- Performance varies with image quality and clarity
|
197 |
+
- Best results with clear, high-contrast historical documents
|
198 |
+
- Continuous improvements through user feedback
|
199 |
