Overview

Written with the jewelry industry in mind, glyptic leverages advanced image processing and generative AI techniques to prepare fingerprint images suitable for jewelry engraving. A two-step process starts by utilizing a pre-trained U-Net model to enhance and denoise raw dactylograms. The second step automates an SDXL-based workflow transforming enhanced images to high-resolution, stylized vector art in SVG format, ensuring compatibility and scalability. Glyptic includes a streamlined setup process that can be deployed on a cloud or local install, and can comfortably run on an M1 Macbook. By generating beautiful yet faithful outputs for even low-quality fingerprints, glyptic significantly benefits the jewelry engraving industry.

Modules

src.glyptic

File	Summary
enhance_fingerprints.py	Enhances fingerprint images by utilizing a pre-trained U-Net model. Downloads necessary model weights if unavailable locally and processes images in batches, resizing and normalizing them before prediction. Outputs enhanced images to a specified directory, optimizing them for further analysis or use within the repository's broader fingerprint processing workflow.
enhance_utils.py	Defines the U-Net model used by enhance_fingerprints.py.
unet_weights.hdf5	Contain pre-trained weights for a U-Net model, facilitating efficient and accurate image processing tasks within the glyptic module. Integrates seamlessly into the workflow, enhancing the systems capability to handle complex image enhancement and fingerprint analysis operations.
glyptic_workflow.py	Facilitates the transformation of input images into high-resolution, stylized outputs using advanced machine learning models and image processing techniques. Integrates various conditioning and control mechanisms to enhance image quality and converts the final output to SVG format, ensuring compatibility and scalability within the repositorys architecture.

src.glyptic_setup

File	Summary
glyptic_setup.py	Facilitate the setup and configuration of the glyptic application by creating necessary directories, generating configuration files, and optionally downloading required model files. Enhance user experience by providing command-line arguments for custom data directories and automated setup processes.
