It helps to understand the movement trajectory of each point motion in the targeted object. It is generally used for facial recognition applications and counting applications. Landmark Annotation : Annotator labels key points at specified locations.It is also used to train warehouse robots so that robots can accurately place boxes in a row. Lines and Splines: Annotators draw lines along the boundaries such as lane separators on the road.However, 3D Cuboid method adds one more dimension, which is the depth of the object. An annotator illustrates the length and width of the object as in the bounding box method. 3D Cuboids: Cuboids are similar to bounding boxes with one difference.Image tagging for e-commerce, retail and damage detection for insurance companies are other application areas for the bounding box method. Tagging elements of phrases or words in NLP helps algorithms identify nuances in the. Entities such as vehicles, pedestrians, traffic lights are identified by bounding boxes so that vehicles can distinguish these entities. Computer vision uses labelling and annotations to pinpoint items in images. In-house labeling also requires investing time training your annotators, which is not optimal if you don’t have enough time and resources. The most common usage of bounding box annotation type is autonomous vehicles. Allowing a third-party company to label your data has its benefits, such as not developing your annotation tools and labeling infrastructure. Bounding Box: Annotators are given an image and are tasked with drawing a box around objects for in-depth recognition of objects in the image data.Annotators draw lines by placing dots around the outer edge of the object they want to classify. Polygon Annotation detects irregular shapes and uneven shaped objects by creating shapes and outlines with an arbitrary number of sides on image data.Autonomous vehicles, robot vision and medical applications are common areas for semantic segmentation. Semantic segmentation is the process of labeling each pixel in an image to a class.Below are the most common ones for videos and images: Basic
