## π― DescripciΓ³n del Problema
|
| 40 |
+
|
| 41 |
+
Los restaurantes espaΓ±oles reciben turistas internacionales que enfrentan barreras significativas:
|
| 42 |
+
|
| 43 |
+
### Problemas Identificados
|
| 44 |
+
|
| 45 |
+
1. **Barrera LingΓΌΓstica**
|
| 46 |
+
- Los menΓΊs estΓ‘n exclusivamente en espaΓ±ol
|
| 47 |
+
- Turistas no hispanohablantes no comprenden los platos
|
| 48 |
+
- TraducciΓ³n literal no transmite el contexto del plato
|
| 49 |
+
|
| 50 |
+
2. **Falta de Contexto Cultural**
|
| 51 |
+
- Nombres como "Tortilla" o "Morcilla" no son descriptivos
|
| 52 |
+
- Los clientes no conocen ingredientes o preparaciΓ³n
|
| 53 |
+
- Se pierden platos tradicionales por desconocimiento
|
| 54 |
+
|
| 55 |
+
3. **Experiencia GastronΓ³mica Limitada**
|
| 56 |
+
- Turistas piden platos "seguros" en vez de locales
|
| 57 |
+
- Restaurantes pierden oportunidad de promocionar especialidades
|
| 58 |
+
- Menor satisfacciΓ³n del cliente
|
| 59 |
+
|
| 60 |
+
4. **Impacto en Ventas**
|
| 61 |
+
- Clientes evitan restaurantes sin menΓΊs traducidos
|
| 62 |
+
- Tiempo perdido explicando platos
|
| 63 |
+

### How it works:
|
| 96 |
+
|
| 97 |
+
1. **OCR Extraction** (LightOnOCR-2-1B) β Extracts text from your menu image (~3-4s)
|
| 98 |
+
2. **Translation** (NLLB-200) β Translates dish names preserving culinary terminology
|
| 99 |
+
3. **Description Generation** (GPT-2 Spanish) β Creates cultural context for each dish
|
| 100 |
+
|
| 101 |
+
### Limitations:
|
| 102 |
+
- Processing time: ~15-20 seconds
|
| 103 |
+
- Works best with clear, well-lit images
|
| 104 |
+
- Maximum 20 dishes per menu
|
| 105 |
+
|
| 106 |
+
### Privacy:
|
| 107 |
+
- All processing happens on this server
|
| 108 |
+
- Images are not stored
|
| 109 |
+
- No data is sent to external APIs

**About Spanish Dining:**
|
| 25 |
+
Spanish meals are social events meant to be enjoyed slowly. Lunch (comida) is typically served 2-4 PM, dinner (cena) after 9 PM. Sharing dishes (tapas style) is common and encouraged.
|
| 26 |
+
|
| 27 |
+
**Regional Diversity:**
|
| 28 |
+
Spain's cuisine varies dramatically by region - from seafood in Galicia to paella in Valencia, each area has unique specialties reflecting local ingredients and traditions.
