What Is The Pottery Shard Identification App?

The pottery shard identification app is a new software tool designed to help archaeologists and researchers identify and classify ceramic artifacts from archaeological sites. The app works by analyzing photos of pottery shards and using computer vision algorithms and machine learning to match the visual characteristics of the shards against a database of known examples. The purpose of the app is to simplify and speed up the process of categorizing and documenting large collections of pottery fragments, which is traditionally a very tedious and time consuming task when done manually by experts.


The development of pottery shard identification apps began in the early 2010s as researchers looked for ways to leverage technology to aid in archaeological analysis. One of the first major projects was ArchAIDE, launched in 2013 by the Institute of Technologies Applied to Cultural Heritage in Italy.1 The goal of ArchAIDE was to create a mobile app that could accurately identify archaeological potsherds using image recognition and machine learning algorithms. After several years of research and development, the ArchAIDE app was released on Android and iOS in 2018.

Since then, other teams have also created pottery shard identification apps and services. In 2018, researchers in China published a paper on developing a method to identify pottery shards based on their unique vibrational characteristics when struck.2 This demonstrates that there are ongoing efforts to explore different technical approaches to automating archaeological analysis tasks like pottery identification.

While early apps focused on classical archaeology, recent developments have expanded the technology to include other cultural traditions. For example, Indian pottery identification apps are now emerging to aid analysis of intricate shard designs from subcontinent antiquity. Overall, pottery shard identification apps represent an important evolution in applying computer vision and pattern recognition to accelerate archaeological workflows.

How it Works

The pottery shard identification app uses advanced image recognition and machine learning technology to identify pottery shards. The app works by comparing photographs of pottery shards to a large database of known examples that have been fed into the system. According to research published on Sciencedirect, the app uses convolutional neural networks (CNNs), a type of deep learning algorithm, to analyze the visual features of the pottery shard and match it against the database.

When a user takes a photo of a pottery shard through the app, the CNN analyzes the shape, color, texture, patterns, and other distinguishing visual characteristics. It then generates predictions of the type, origin, age, and other attributes of the shard by finding the closest match in the reference database. The app provides a percentage confidence rating along with the identification to indicate the certainty of the match. As more pottery data is added to refine the algorithms, the accuracy of the identifications continues to improve.

Overall, the image recognition and machine learning capabilities allow the app to quickly and reliably identify pottery shards without requiring a human expert. This makes it an invaluable tool for archaeologists, historians, and collectors seeking to learn more about unearthed ceramic artifacts.


The ArchAIDE pottery shard identification app offers a variety of useful features and capabilities to help analyze and identify archaeological artifacts. According to the Google Play store page (ArchAIDE – Apps on Google Play), some of the key features include:

– Automatic photo recognition – The app can automatically analyze photos of pottery shards and suggest possible matches from its database of examples. This allows for quick on-site identifications without requiring ceramic experts.

– Large database – ArchAIDE contains over 30,000 images of ceramics covering styles from ancient Greece to modern times. This extensive database improves the accuracy of the automatic recognition.

– Manual search tools – Users can manually browse the database and narrow down searches by time period, region, decoration style, shape, and other attributes. This supplements the automatic recognition.

– Save and organize findings – Identified shards can be saved, tagged, annotated, and organized within the app for further study and documentation.

– Share discoveries – The app enables exporting and sharing shard information and collecting statistics on excavation results.

– Camera optimization – The camera interface is optimized for taking clear, well-lit photos ideal for analysis and identification by the app.

– Available offline – Once downloaded, the database can be accessed offline in remote locations with no connectivity.

By leveraging machine learning and computer vision technology applied to its extensive visual database, the ArchAIDE app provides both professional archaeologists and amateurs with a powerful tool for quickly identifying pottery shards in the field.


The ArchAIDE app has a simple and intuitive interface that makes identifying pottery shards easy for both experts and amateurs alike. When the app is opened, it presents the user with two main options – “Scan & Recognize” and “My Finds.”

The “Scan & Recognize” option allows users to take a photo of the pottery shard they want to identify. The app uses the camera on the user’s device to capture the image. There are guides on the screen to help center and focus the image properly. Once the photo is taken, the app uploads it and within seconds provides information about the type, time period, origin, and more based on image recognition technology (Inera).

Under “My Finds,” users can browse all the pottery shards they have previously identified and saved using the app. This provides a catalog of finds that can be referenced later. Users can also add notes and details to each logged find (Google Play).

Overall, the app is designed to be simple enough for everyday users while still providing robust identification capabilities. The image recognition and database behind it leverages research and expertise to identify pottery effectively.

Identification Process

The pottery shard identification app follows a simple step-by-step process to identify an unknown shard submitted by the user:

1. The user opens the app and captures a photo of the shard or uploads an existing photo. The app’s interface guides the user to take a clear, well-lit photo showing multiple angles and closeups of the shard.

2. The photo is uploaded to the app’s servers where computer vision algorithms analyze visual features like color, texture, shape, and decorative patterns. The algorithms compare these features to a database of known shards to find possible matches (see Anichini et al. 2021).

3. The app displays the top matching results with percentages indicating confidence levels. The user can tap each result to see more details like the type, origin, age, and other attributes of the matched shards in the database.

4. If the user is unsatisfied with the results, they can retake photos of the shard and resubmit to get new results. The app also allows manually specifying attributes like color and shape to improve the search.

5. Once the user finds a satisfactory match, they can save and share the results. The app creates a report with the shard details, photos, match percentages, and citations.

This iterative process leverages computer vision and a comprehensive database to provide an accessible way for archaeologists and hobbyists to identify mysterious pottery shards.


The pottery shard identification app uses advanced computer vision and machine learning algorithms to identify and classify ceramic fragments. In initial testing, the app was able to correctly identify pottery types with approximately 70-90% accuracy depending on the dataset used (Anichini, 2021).

The app’s image recognition is quite robust and can identify potsherds from a single photograph taken on a mobile device. This removes the need for specialized imaging equipment. However, there are some limitations on accuracy based on image quality and lighting. Very small fragments or pieces with unclear features may be misclassified.

Overall, the app provides archaeologists with a powerful new tool to quickly and easily get an initial classification on unknown ceramic fragments in the field. While the identification may not be 100% accurate, it dramatically narrows down the possibilities to guide further research. Experts emphasize the tool is meant to complement not replace traditional archaeological examination and verification of finds (CORDIS, 2021).
