  • Contextual labeling and document-level classification for use cases like content moderation, legal text analysis, and customer support automation.
  • Multilingual annotation support with attention to tokenization, grammar structures, and semantic differences across languages.

• Video Annotation Services

  

  • Detailed frame-by-frame tracking using bounding boxes, keypoints, or segmentation masks to train models in action recognition and behavior analysis.
  • Event tagging for identifying specific actions, gestures, or movements in surveillance, sports, or retail video footage.
  • Temporal segmentation services to define scene transitions, activity windows, or detect anomalies in extended video sequences.

• Speech Recognition

  

  • Accurate time-stamped transcription of audio files to support the development of high-performance speech recognition systems.
  • Speaker diarization and segmentation services to distinguish between multiple voices in interviews, meetings, or customer support calls.
  • Labeling non-speech audio elements such as coughs, background noise, or ambient sounds for healthcare, security, and voice-enabled applications.

• Semantic Segmentation

  

  • Pixel-level annotation for distinguishing objects and backgrounds with high precision in applications like medical diagnostics, self-driving technology, and satellite imagery.
  • Support for complex and high-resolution datasets that require fine-grained segmentation of detail and contextual accuracy.
  • Multi-stage quality checks to ensure annotation accuracy and reduce false positives in training data.

• Bounding Box Annotation

  

  • Clear and accurate box placement around visible objects in images for object detection use cases in retail, agriculture, logistics, and autonomous driving.
  • Ability to handle multiple object classes and sub-classes within the same image for complex model training needs.
  • Output formatting tailored to your machine learning workflow, with support for YOLO, COCO, Pascal VOC, and other dataset structures.
