Identifying Rug Origins: Tips and Tricks & How AI Can Help

Rugs are more than just decorative items; they are stories woven into fabric, each thread holding a piece of history and culture. Whether you're an avid rug collector, an interior design enthusiast, or simply curious about the beautiful rug adorning your living room, understanding the origins of a rug can greatly enhance its value and significance. In this blog post, we'll explore traditional methods of identifying rug origins and distinguishing handmade from machine-made pieces. We'll also delve into the fascinating world of AI technology and how it is revolutionizing rug identification. Stay with me on this journey as I'm going to blend the time-honored expertise with cutting-edge innovation to help you uncover the story behind your rug.

Traditional Methods for Identifying Rug Origins and Types

Examining Materials

The foundation of any rug lies in its materials. By understanding what a rug is made from, you can gain significant insights into its origins.

• Wool Rugs: Predominantly found in Persian and Turkish rugs, wool is prized for its durability and natural sheen. If your rug feels soft and slightly oily to the touch, it's likely made of high-quality wool.
• Silk Rugs: Often used in finer Persian and Chinese rugs, silk lends a luxurious texture and a subtle sheen that catches the light beautifully.
• Cotton Rugs: Commonly used in the foundation of many rugs, particularly those from India and China.

Analysing Patterns and designs

The intricate designs on a rug are like fingerprints, unique to their regions of origin.

• Geometric Patterns: These are hallmarks of Baluch, Turkish and Caucasian rugs, characterized by their bold, symmetrical designs.
• Floral Motifs: Delicate floral patterns are often seen in Persian rugs coming from central and north western parts of Iran
• Tribal Designs: Rugs from Tribes in Iran and Central Asia often feature striking, symbolic motifs reflecting the nomadic lifestyles of their creators.

Inspecting Weaving Techniques

The way a rug is woven can reveal a lot about its origin and quality.

• Knot Density: A rug with a higher knot density (knots per square inch) generally indicates finer craftsmanship and higher quality. Persian rugs are known for their high knot density.
• Knot Types:
  • Persian Knot (Senneh): This asymmetrical knot is tighter and more intricate, commonly found in Persian rugs.
  • Turkish Knot (Ghiordes): Symmetrical and double-looped, this knot is typical in Turkish and Caucasian rugs.

Determining Handmade vs. Machine-Made Rugs

Spotting the difference between handmade and machine-made rugs can be tricky but rewarding.

• Back of the Rug: Turn the rug over. Handmade rugs usually have irregular knots and slight imperfections, which are signs of human craftsmanship.
• Fringe: In handmade rugs, the fringe is an extension of the warp threads and integral to the rug's structure. Machine-made rugs often have a fringe sewn on after completion.

AI Techniques can help for Identifying Rug Origins

As mentioned above, Identifying a rug involves many factors, such as the materials used, patterns and designs, and weaving techniques—all of which require an expert eye to evaluate accurately. Through the Rugswise project, I've been testing whether an artificial intelligence model can be trained to recognize what an expert sees in a rug. Among these factors, patterns and designs have proven to be the most learnable by the model, while distinguishing materials or weaving techniques remains more challenging for AI. The reality with AI is that the more samples we use for training, the better it learns. However, some error in AI predictions is inevitable, and continuous improvement is needed to refine these models. If we can accept this level of uncertainty, AI-based methods can be useful; otherwise, there is currently no substitute for an expert assessment and that is why in Rugswise we also have provided you the option to request for expert rug appraisal.

Now in order to introduce you the idea behind Rugswise AI-based rug identification initiative, here I'd want to explain how this AI-based system is designed to work.

Feature Extraction with AI

• Patterns and Colors: Rugswise meticulously analyzes the intricate designs and color schemes of your rug. This process involves breaking down the rug’s visual elements and matching them with known patterns from various regions.
• Image Recognition: The deep learning models developed by Rugswise are trained on extensive datasets of rug images. This training enables our tool to classify rug types and origins with remarkable precision, providing you with a detailed understanding of your rug’s background.

Futuristic Knot Analysis with AI

• High-Resolution Imaging: By capturing detailed images of the knots in your rug, AI can analyze the weaving techniques used. This high-resolution imaging is crucial for identifying the subtle differences between handmade and machine-made rugs.
• Pattern Recognition:  AI will be able to differentiate between handmade and machine-made knots by examining their consistency and uniformity. Handmade knots often show slight variations, a testament to human craftsmanship, which our tool can detect and analyze.

Practical Applications of AI-Powered Rug Identification Tool

• Accessibility: It has been designed to be easy to use, making initial rug identification accessible to both enthusiasts and professionals. Simply upload a photo of your rug to get started.
• Accuracy and Efficiency: AI improves with practice—the more samples it sees, the more accurate it becomes. For the rug types where we've gathered more data, we've achieved good accuracy and precision. However, work is still ongoing for other rug types. Leveraging the power of computer vision has made the process of rug identification more accessible. With this vision, you can get initial information about your rug in a fraction of the time, from anywhere, and for any further information, you can discuss it with an expert.
