DreamSim Scoring

Evaluates 3D reconstruction quality by comparing rendered views with input images.

Files

score_recon.py

Scores reconstruction quality using DreamSim.

Output: {original/edited}_3d/recon_result.json with structure:

{
  "uid": {
    "min_width": 245,
    "max_width": 512,
    "distances": {
      "view_0": 0.0876,
      "view_1": 0.1123,
      "view_2": 0.0945,
      "view_3": 0.1034
    }
  }
}

Filtering Logic:

• Filters out poor 3D reconstructions using perceptual similarity
• Only pairs passing DreamSim filter proceed to VLM verification

Usage

python3 dreamsim/score_recon.py <recon_dir> <input_dirs> <result_path>

Parameters:

• input_dirs: Comma-separated list of directories containing input images (e.g., dir1,dir2)
