# FlowSlider – Continuous Image Editing via Flow Matching

**FlowSlider** extends [FlowEdit](https://huggingface.co/papers/2412.08629) with a
3-prompt directional decomposition that gives you a continuous **scale** knob over
the edit intensity — from "no change" to "full edit" and beyond.

## Algorithm

```
V_direction = V_pos − V_neg          (pure editing direction)
V_delta     = (V_neg − V_src) + scale × V_direction
```

| scale | effect |
|-------|--------|
| 0.0 | no edit |
| 1.0 | full positive-target edit |
| > 1 | exaggerated / over-edit |

## How to use

1. Upload a source image.
2. Fill in **Source Prompt** (describe the image), **Positive Target Prompt** (desired result), and optionally a **Negative Target Prompt** (the "opposite" direction; leave blank to default to the source prompt).
3. Enter one or more **scales** as comma-separated values (e.g. `0.0, 0.5, 1.0`).
4. Click **Generate** — the gallery shows the original plus one result per scale.
