Image Labeling – Short Conceptual Explanation

Image labeling is the process of identifying and marking various details in an image. Image labeling is useful when automating the process of generating meta data or making recommendations to users based on details in their images. This process can utilize on-device and cloud based technology to detect details in images automatically.

Crowdsourcing can be used for image labeling in two ways; on the one hand images can be labeled via the crowd and on the other hand can help to ensure / to verify that details of an image are correctly identified and labeled.

What is Image Labeling?

Image labeling involves identifying an image as a whole, but it can also involve identifying various aspects within an image. For example, the process is straightforward for pictures that contain a single image, like a portrait photograph. Labeling an image can be more difficult for shots that include more details, like a wide-angle picture taken at a public place.

A few aspects of an image that could be labeled and identified include:

  • Faces
  • Animals
  • Landscape details
  • Text recognition
  • Colors
  • Activities
  • Fictional characters
  • Occupations
  • And more

The more detail is included in the image label, the more information it can offer. For example, labeling an image as a mountain landscape can be helpful, but it’s even better if the mountain range can be identified.

Depending on the details in the image and how detailed the description is, image labeling can be a lengthy process that contains a lot of information about what can be seen in the picture.

Uses for images that have been labeled

There are many uses for image labeling, and they will continue to be important as the future of the internet unfolds.

Today, image labeling and face recognition softwares can make using social media and cataloguing pictures in an online album a lot easier. Photos can automatically be categorized based on their content and they can be labeled automatically without the need to identify each image individually.

It can be helpful for businesses and content producers as well. Meta data can be automatically generated based on the images and content on a page, without the need for it to be generated word by word. It can also be used to describe images on a website. Not only can that help with search engine optimization, it also makes websites more engaging for the visually impaired.

In addition, the future of labeling images may make advertising easier based on the information that can be obtained from customer images.

Image Labeling using APIs

An efficient way to label images is to use an application programming interface (API). They can be downloaded to a device or they can be used in cloud-based applications.

Device-specific programs have the benefit of being able to be utilized without an internet connection. Because the program is self-contained, it is also the quickest way to label the various aspects of an image.

However, device-specific programs aren’t always very accurate. They can also be lacking when it comes to details. If the most accurate, detailed information is of the utmost importance, a cloud-based application is a better choice.

There are many different providers that offer both device-specific and cloud-based programs. Most also include a confidence score that makes it easy to check the image labeling on large batches of images.

Image Labeling using crowdsourcing

Image labeling can also be obtained using crowdsourcing. Crowdsourcing is the practice of utilizing the services of a crowd of people on the Internet to complete a task, like labeling images.

Crowd workers can be utilized to provide details in images that go above and beyond the details that can be provided with software programs. For example, a home can be identified according to the neighborhood it is located in, not just by its color or style.

Crowdsourcing can also be utilized in conjunction with image labeling software. Workers can review the information that is listed for each image, which includes the confidence scores, to ensure the information listed with each picture is accurate.
