CVATImageBounding Box

As an Image Annotator at Samasource, I annotated images for AI datasets, focusing on quality and accuracy. My work included drawing bounding boxes and performing image classification and segmentation tasks for computer vision projects. I consistently met productivity targets while ensuring data quality and precise annotations. • Labeled thousands of images using bounding boxes and polygon tools. • Performed classification and tagging to aid machine learning models. • Maintained high data labeling accuracy above 98%. • Used Sama's proprietary annotation software and tracking systems.
