Basic concepts of visual big data

Visual big data encompasses the vast quantities of image and video information generated daily, presenting significant challenges in storage and analysis within the realm of digital media technology.

Definition of visual big data

Visual big data refers to the extensive datasets comprised of visual content, including images and videos, that are collected from various sources such as mobile applications and public surveillance systems.

Importance

The exponential growth of visual data necessitates advanced methods of storage, management, and analysis, highlighting its importance in the era of digital information overload.

Data types and structures

Data can be divided into structured and unstructured forms, with the majority being unstructured and consisting of complex formats like multimedia files, requiring specialized techniques for processing.

Data generation sources

Visual big data is generated through machine-to-machine interactions, human interactions on social platforms, and transactions within business systems, reflecting the convergence of web and mobile technologies.

Data expansion

Enterprise data is expanding from Web 1.0 to Web 2.0 and beyond, encompassing the Internet of Things, contributing to the vast datasets characteristic of the modern information age.

Characteristics of big data

Big data is characterized by the “four Vs”: Volume, Variety, Velocity, and Value, describing its immense size, diverse formats, rapid generation, and potential for insights.

Additional characteristics

Beyond the “four Vs,” big data also involves aspects such as Veracity, Variability, and Vicinity, emphasizing the accuracy, changeability, and proximity of data sources.

Characteristics of visual big data

Visual big data is distinguished by its larger sample sizes, more complex data forms, and a focus on correlation rather than causation, prioritizing the “what” over the “why” in data analysis.

The study and application of visual big data represent a frontier in digital media technology, requiring innovative approaches to handle the vast and complex visual information generated in our increasingly connected world.
