What is a PDF annotator?
The process of labeling image data to help the computer vision-based models easily identify the object of interest is known as an image annotation. Labeling is done using tags and meta tags to enable the smart models to calculate attributes easily. There are different types of image annotation techniques. Some of these are mentioned below. Semantic Segmentation - Unlike other annotation techniques, semantic segmentation focuses on specifications and precision. It is the process of adding tags to each pixel in the image. This is used to prepare training data for autonomous vehicles, medical imaging devices. 2D Bounding Boxes - In this technique, boxes are drawn around the objects of interest within the image. This box should be drawn close to every edge of the object. One specific application of the bounding boxes technique is autonomous vehicle development wherein annotators draw boxes around elements such as vehicles, pedestrians, and cyclists. 3D Cloud Point Labeling - There is a slight difference in the 2D bounding boxes and 3D cloud point labeling technique. The first one depicts only length and width whereas the latter one labels length, width, and approximate depth. Polygons - With polygons, dots are placed around the outer edge of the object. It is just like connecting the dots while placing the dots at the same time.
