Bounding BoxAs a model trainer, I performed bounding box and polygon annotation on road vehicles, pedestrians, traffic lights, and more, using both open-source and proprietary tools. I classified and labeled various object attributes such as vehicle type and color as part of image annotation tasks. I also participated in pixel-level semantic segmentation of areas like road surfaces and obstacles to meet strict project quality standards. • Utilized tools such as LabelImg, VGG Image Annotator (VIA), and enterprise/internal labeling software • Conducted daily cross-checks for logic errors and accuracy in team annotations • Reported edge cases to PMs/algorithm engineers for rule refinement and annotation guideline improvement • Maintained quality inspection documentation and ensured ongoing compliance with project norms
