Filtering

Select the best synthetic images based on point-to-distribution quality scores.

Methods

Method	Description
top-k	Keep the k images with smallest distances
top-p	Keep the top proportion (0 ≤ p ≤ 1) of images
threshold	Keep images with distance ≤ value

Usage

from ciagen import filter_generated

kept = filter_generated(
    generated="data/generated/",
    method="top-k",
    value=100,
)

CLI

ciagen filter \
    --generated data/generated/ \
    --method top-k \
    --value 100

Requirements

The generated directory must contain a metadata.yaml file with PTD scores (created by evaluate()). If ptd_scores is provided directly, the metadata file is not needed.
