-# stain-normalization
+# Stain Normalization
+
+Tento repozitár slúži ako doplnkový materiál k bakalárskej práci **"Normalizácia farbenia histopatologických snímkov pomocou neuronových sietí"**.
+
+Celý kód nie je možné spustiť samostatne, pretože vyžaduje prístup k citlivým dátam a k platforme na správu strojového učenia MLflow. Avšak je možné spustiť demo, ku ktorému je pripravených pár vzoriek na demonštráciu.
+
+## Demo
+
+Demo skript umožňuje načítať jeden obrázok alebo celý priečinok, normalizovať ich pomocou predtrénovaného modelu a uložiť výsledné obrázky do určeného priečinka.
+
+## Priložené dáta
+
+- **Originálne obrázky** (v priečinku `./demo_data/original`) – referenčné vzorky.  
+- **Upravené obrázky** (v priečinku `./demo_data/modified`) – referenčné obrázky s modifikovaným sfarbením, ktoré sa následne modelom znormalizujú späť k originálnemu vzhľadu.  
+- **Obrázky z iného datasetu** (v priečinku `./demo_data/to_predict`) – ukazujú, ako model dokáže prispôsobiť farby vstupov tak, aby zodpovedali farebnému štýlu trénovacích dát.  
+- **Model checkpoint** 
+
+## Spustenie dema
+
+Projekt je spravovaný pomocou nástroja **pdm**, ktorý umožňuje jednoduchú správu závislostí a prostredia. Stačí nainštalovať závislosti pomocou:
+
+```bash
+pdm install
+```
+a potom spustiť demo skript:
+
+```bash
+pdm run python demo.py --input ./demo_data/modified
+```
+
+## Dostupné arguemnty:
+- **input**: cesta k obrázku alebo priečinku s obrázkami na normalizáciu (default ./demo_data/modified)
+- **output**: priečinok, kam sa uložia normalizované obrázky (default ./demo_data)
+- **use_cpu**: defaultne nadstavené na použitie GPU ak je dostupná, avšak ak by nastali problémy odporúčam použivať iba CPU
