Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.

Introduction

Module by: Jash GUO. E-mail the author

Summary: This module introduces motivations and approaches of our project.

Abstract

A canvas can be characterized by the vertical and horizontal weave densities while the actual painting serves as an additive signal that only distracts from the thread-counting process. The thread counting algorithm and the spectral techniques we employ in our project can analyze weave density for entire paintings with an accuracy comparable to human measurements more efficiently.

Motivation

Van Gogh Museum of Amsterdam has a collection of artist's works and is looking for a more advanced analysis for sequencing paintings in addition to the traditional manual methods. Our whole-painting analysis shows that frequency distributions should match if two paintings are from the same canvas roll. This could better support the forensic evidence quantitatively when comparing two paintings.

Approach

Current Approach

Human measurement – weave threads are manually counted and compared. This approach is inefficient and may not be accurate.

Our New Approach

Use thread counting algorithm and spectral techniques to analyze weave density for entire paintings. Frequency distributions of weave densities should match if two paintings are from same canvas roll.
