# Visual Cortex - Cell Detection Tool

A Streamlit web application for automated detection and counting of circular cells in microscopy images.

## Features

- **Multi-channel TIFF support**: Load and preview 4-channel microscopy images (up to 1GB)
- **Interactive parameter tuning**: Real-time adjustment of detection parameters
- **Slice preview**: Test settings on small image regions for fast iteration
- **Advanced detection pipeline**: Uses thresholding, morphological operations, and watershed segmentation
- **Export results**: Download annotated images and detection data as CSV

## Usage

1. Upload a .tif/.tiff microscopy image
2. Preview different channels to select the best one for analysis
3. Adjust detection parameters using the settings panel
4. Test on a small slice first for quick feedback
5. Run full detection when satisfied with parameters
6. Download results (overlay image + CSV data)

## Detection Parameters

- **Threshold method**: How to separate cells from background (percentile/otsu/sauvola)
- **Cell separation**: Split touching cells using watershed segmentation
- **Filtering**: Remove false positives based on shape and contrast
- **Size constraints**: Set minimum cell diameter in microns

## 🚀 Easy Local Setup (Recommended)

**For non-technical users:** See [EASY_SETUP.md](EASY_SETUP.md) for one-click installation!

**Quick start:**

- **Windows:** Double-click `setup_and_run.bat`
- **Mac/Linux:** Run `./setup_and_run.sh` in terminal

## 🔧 Manual Development Setup

```bash
pip install -r requirements.txt
streamlit run streamlit_app.py
```

## ⚡ Why Run Locally?

- **No file size limits** (upload 1GB+ files)
- **Faster processing** (uses your computer's resources)
- **More reliable** (no network timeouts)
- **Works offline** after initial setup
