Though there are multiple types of image annotation techniques, few of which are used in the industry. Let’s find out the popular one and which one is suitable for different perception-based models to make the prediction accurate.

Bounding Box Annotation
Making a rectangle drawing of lines from one corner to another of an item in an image according to its shape to make it completely visible is known as bounding box annotation. 2D Bounding Box and 3D Bounding Box annotation are used to annotate objects for machine learning and deep learning.

Semantic Segmentation
The technique of analyzing images to determine the boundary lines of regions that may be identified as belonging to a given class of item is known as semantic segmentation. In simple terms, Semantic segmentation is a method of evaluating digital images to find the boundary lines of regions that may be identified as belonging to a specific item class.

Landmark Annotation
The labeler must label significant points at certain places for landmark annotation. These labels are frequently used in counting and gesture or facial recognition applications. Keypoint annotation is used by counting apps to specify the density of the target object within a scene.

Polygon Annotation
Polygon annotation is a precise method of annotating objects that involves picking a sequence of x and y coordinates along their edges. As a result, polygon annotation can have pixel-perfect precision while remaining extraordinarily versatile and adaptive to various forms.

Polyline Annotation
The Polyline annotation allows you to draw shapes and outlines on a page with an arbitrary number of sides. The Polyline is similar to the Polygon except that it can have an open end or side. While sketching, hold down the Shift key to create horizontal, vertical, or 45-degree angle lines. Shapes may be resized by sliding any of the resize handles on the vertices of the form once it has been placed.

3D Cuboid Annotation
Bounding boxes are comparable to 3D cuboid annotation, except they give more depth information about the item. As a result, 3D cuboids may be used to generate a 3D representation of an item, allowing systems to identify properties such as volume and location in 3D space.

LIDAR Annotation
Lidar annotation designates anatomical or structural sites of interest, resulting in accurate datasets that determine the form of various-sized objects, allowing machine learning algorithms to recognize tiny pictures.

3D Point Cloud Annotation
In order to get the dimensions correct, 3D point cloud annotation allows you to see an item for more thorough identification and categorization.

Different types of data use cases

Cars’ computer vision systems will be able to discern between roadways, walkways, and the sky by allowing them to gain a well-trained awareness of their surroundings reinforced by artificial intelligence and autonomous vehicle annotation.

Autonomous Flying
The information included in satellite and drone images may provide detailed insight into major global meteorological and environmental events. Annotating a satellite image correctly may add value to the image by allowing professionals to collect, preserve, and share information about the area.
