What is ISO 23938:2012?

ISO 23938:2012 is a technical standard that provides guidelines for the implementation of feature extraction and similarity measures for content-based image retrieval (CBIR) systems. CBIR is a technology used to search and retrieve images from large databases based on their visual content rather than textual descriptions or tags.

Importance of ISO 23938:2012

The standard plays a crucial role in ensuring interoperability and effectiveness of CBIR systems. By providing a common framework, it enables different systems to communicate and exchange data seamlessly, improving efficiency and accuracy in image retrieval tasks.

Key Components of ISO 23938:2012

ISO 23938:2012 defines several key components necessary for the implementation of CBIR systems:

Feature Extraction: The standard outlines various feature extraction methods, such as color, texture, and shape, which are essential for describing visual characteristics of images.

Similarity Measures: It defines algorithms and techniques to quantify the similarity between query images and database images, allowing for efficient retrieval of similar images.

Metadata: The standard establishes guidelines for metadata representation, including the description of image features and administrative information, facilitating organization and management of image databases.

System Evaluation: ISO 23938:2012 provides methodologies for evaluating the performance and quality of CBIR systems, enabling researchers and developers to assess and compare different implementations.

Benefits and Applications

The adoption of ISO 23938:2012 brings numerous benefits. Firstly, it enhances the consistency and compatibility of CBIR systems, allowing users to seamlessly integrate different software and hardware components. Secondly, it improves the accuracy and efficiency of image retrieval by establishing standardized algorithms and measures. Thirdly, it promotes research and development in the field, as the standard provides a common reference point for evaluating and comparing new advancements.

CBIR systems find applications in various fields, including healthcare, digital libraries, e-commerce, and security. Medical professionals can utilize CBIR to locate similar images for disease diagnosis and treatment planning. Digital libraries can benefit from efficient image retrieval, enhancing user experience. E-commerce platforms can use CBIR to recommend visually similar products to customers. Security agencies can employ CBIR for surveillance and forensic image analysis.

In conclusion, ISO 23938:2012 is a crucial standard in the field of content-based image retrieval (CBIR). By providing guidelines for feature extraction, similarity measures, metadata, and system evaluation, it promotes interoperability, accuracy, and efficiency of CBIR systems. Its adoption brings numerous benefits across various industries and facilitates advancements in the field.
