+# ReChannel: Pixel-Space Dense Prediction with Text-to-Image Models
+
+This repository contains the weights for **ReChannel** presented in [From RGB Generation to Dense Field Readout: Pixel-Space Dense Prediction with Text-to-Image Models](https://huggingface.co/papers/2607.06553).
+
+ReChannel reads dense prediction targets (such as depth, surface normals, matting, and referring segmentation) out of a FLUX-Klein text-to-image DiT with lightweight per-task LoRA adapters on the (otherwise frozen) backbone. 
+
+* **Code:** [GitHub Repository](https://github.com/xmz111/ReChannel)
+
+## Quick Start (Inference)
+
+To run the model locally, please clone the GitHub repository and install the dependencies:
+
+```bash
+git clone https://github.com/xmz111/ReChannel.git
+cd ReChannel
+pip install -r requirements.txt
+```
+
+You can then run dense prediction tasks on a single image:
+
+```bash
+python infer.py --image assets/demo_input.jpg \
+    --tasks depth,normal,matting,refseg \
+    --phrase "the right couch" \
+    --out out.png
+```
+
+- `--tasks`: any subset of `depth, normal, matting, refseg`.
+- `--phrase`: the referring expression used by `refseg` (text-conditioned).
+
+## How it works
+
+```
+RGB --VAE encoder--> latent tokens --DiT (frozen θ + task LoRA Δt, σ=0)--> token field Z_t
+    --  Ŷ = reshape( W_t · z_ij + b_t ) ∈ R^{p×p×K}  --tile over the plane-->  dense field
+```
+
+The backbone is frozen; only a lightweight per-task LoRA adapter and the token-local linear head are trained. The head has no spatial mixing — all spatial structure comes from the adapted token field, not the head.
