What is image labeling?

Image labeling is a form of data labeling that involves the identification and the tagging of varied details of an image.

Types of image labeling

Object detection

It is a technique used in computer Vision to identify as well as locate objects in digital images or videos. It detects a targeted object in the video or image.

Classification

Classification refers to the assignment of an object to an image. In other words, finding which classes of objects are present in an image or a video.

Semantic segmentation

It is the process of categorising each pixel of an image with a particular label or description.

What is transfer learning

Transfer learning is a branch of machine learning which stores accumulated or gained knowledge in the process of solving a problem, eventually applying that knowledge to a similar problem.

Types of transfer learning

Positive transfer learning

It is the enhancement of current learning based on previously learned knowledge. It also refers to when models use learned knowledge to improve the end result of new tasks.

Negative transfer learning

It is the transfer of less related sources of knowledge by training models for tasks, which often results in unpleasant results.

Ways of speeding up image labeling

Classification 

Localization

It seeks to locate the most visible object in an image or video. Usually, it is centered within a tightly cropped bounding box. It easily ascertains the location of an image object.

D-CNN

Deep Convolutional Neural Networks process the Red, Green, and Blue elements of an image concurrently. It lowers the amount of needed artificial neurons for image processing. They receive and train images as classifiers. It makes use of a mathematical operation known as “convolution”.

MAIA

It starts with the automated detection of interesting objects in an image, which is based on the assumption that they are more easily distinguishable from a uniform background. These interesting objects are used as training proposals which are further observed and only the most interesting filtered manually. They are then used to train the machines for automated detection of selected objects. There is a further manual filtering to find the objects which are actually considered the interesting ones.

Benefits of image labeling in transfer learning

It produces results nearly as accurate as that which stems from individual human effort. The trained models are used for training machines.

It also in addition provides visual representations or information about objects and the materials they are made out from.

Best use case of image labeling in transfer learning

Medical Imaging

Medical imaging has been used especially for diagnosis with the use of x-ray images, and also for tissue detection. The use of convolutional neural networks (CNN) for medical imaging has come at the right time.

In lung segmentation and luminary model detection for cancer patients, this is also used. Nodules are signs of tumors or cancers. Medical imaging is helping in this regard to detect them.
