Semantic and Segmentation

ImageBounding Box

In semantic segmentation and instance segmentation within a dataset annotation task, there are processes through which images will be labeled based on the outlines of objects or parts of an image according to certain project requirements. In semantic segmentation, the pixels are assigned classes that may include, but are not limited to, crops, soil, or roads, whereby no individual object is separated from others. In instance segmentation, each object in the same class has to be segmented and labeled individually; for example, different crop plants within a single farm.

CVAT for bounding boxes and LiDAR point cloud labeling(Remote)

ImageBounding Box

This particular project was aimed at the training of AI algorithms for smart farming based on image and LiDAR datasets. Within the process of annotation, there have been established different kinds of agricultural objects such as crops, livestock, agricultural machinery, pests, etc., by means of bounding boxes with the help of CVAT tool, and LiDAR points cloud labels, which helped to classify terrain, vegetation, and spatial objects for further 3D mapping and analytics. In the framework of this project, large volumes of data had to be analyzed and processed that meant thousands of images and point cloud frames. High-quality annotations have been performed according to all the standards and criteria.
