Computer Vision Annotation

Precise image and video annotation services for your computer vision models

2D/3D Bounding Boxes

Accurate object localization with rectangular bounding boxes for object detection models with support for both 2D and 3D applications.

How It Works:

Our annotators draw precise rectangular boxes around objects of interest, labeling them with appropriate classes and attributes. For 3D applications, we create cuboids that represent object dimensions in three-dimensional space.

Client Benefits:

  • Faster model training with precisely localized objects
  • Improved object detection accuracy
  • Reduced false positives in detection systems
  • Support for multi-class object recognition
  • Multi-class object detection
  • Occlusion and truncation handling
  • Attribute classification
  • 3D cuboid annotation

Semantic Segmentation

Pixel-level labeling for detailed scene understanding and precise object recognition with fine-grained categorization.

How It Works:

Our expert annotators meticulously label each pixel in an image with a corresponding class label, creating detailed masks that distinguish between different objects and regions, even in complex scenes with overlapping elements.

Client Benefits:

  • Enhanced scene understanding capabilities
  • Precise boundary detection for critical applications
  • Improved accuracy in medical imaging and autonomous systems
  • Better performance in complex environments
  • Pixel-precise masks
  • Multi-class segmentation
  • Boundary accuracy optimization
  • Instance segmentation support

Keypoint Annotation

Precise landmark detection for pose estimation, facial recognition, and gesture detection models with custom skeleton configurations.

How It Works:

Our annotators place precise points on specific features or landmarks according to custom-defined skeletons. These points can represent joints for pose estimation, facial features for emotion recognition, or parts of objects for detailed analysis.

Client Benefits:

  • Accurate pose estimation for fitness and health applications
  • Enhanced facial recognition systems
  • Improved gesture control interfaces
  • Detailed analysis of movement and form
  • Custom skeleton definition
  • Visibility state tagging
  • Connective relationships
  • Multi-person annotation

Polygon Annotation

Detailed outlining of objects with irregular shapes for high-precision computer vision applications.

How It Works:

Our annotators create complex polygons by placing vertices along the edges of objects, precisely following their contours regardless of shape irregularity. This method provides much more accurate representations than bounding boxes.

Client Benefits:

  • Superior accuracy for irregularly shaped objects
  • Reduced background noise in training data
  • Better performance on complex objects
  • Improved edge detection capabilities
  • Complex shape handling
  • Instance segmentation
  • High-precision requirements
  • Vertex-level editing

NLP & Text Annotation

Comprehensive text data services for natural language processing models

Text Classification

Categorizing text into predefined groups for sentiment analysis, topic modeling, and content classification.

How It Works:

Our language experts analyze text content and assign appropriate categories based on your taxonomy. This can include sentiment (positive, negative, neutral), topic categories, intent detection, or any custom classification system you require.

Client Benefits:

  • Improved content categorization systems
  • Accurate sentiment analysis for customer feedback
  • Enhanced spam and content moderation filters
  • Better user intent recognition
  • Sentiment analysis
  • Topic categorization
  • Intent recognition
  • Multi-label classification

Named Entity Recognition

Identifying and tagging key entities in text for information extraction and knowledge graph development.

How It Works:

Our annotators identify and label entities in text according to predefined categories such as person names, organizations, locations, dates, and custom entity types. We can also identify relationships between entities for more complex knowledge extraction.

Client Benefits:

  • Enhanced information extraction systems
  • Improved search and recommendation engines
  • Better content summarization capabilities
  • Efficient knowledge graph development
  • Entity recognition
  • Relationship extraction
  • Custom entity types
  • Cross-document coreference

Audio & Speech Annotation

Precise audio data services for speech recognition and sound detection models

Speech-to-Text Transcription

Accurate transcription of speech with speaker diarization and timestamping for voice assistant training.

How It Works:

Our linguists transcribe audio content while identifying different speakers, marking timestamps for each utterance, and noting speech characteristics like accents, emotions, and background noise conditions.

Client Benefits:

  • Highly accurate training data for speech recognition systems
  • Improved voice assistant performance across diverse accents
  • Better speaker identification capabilities
  • Enhanced natural language understanding
  • Multi-speaker identification
  • Timestamp annotation
  • Accent and dialect coverage
  • Background noise handling

Sound Event Detection

Identifying and classifying sound events for environmental monitoring and audio surveillance applications.

How It Works:

Our audio specialists label specific sound events within audio recordings, marking their start and end times while categorizing them according to your classification system, from emergency sirens to wildlife sounds.

Client Benefits:

  • Accurate environmental sound recognition systems
  • Improved security and surveillance applications
  • Enhanced content-based audio retrieval
  • Better audio context understanding
  • Sound classification
  • Event timestamping
  • Acoustic scene analysis
  • Multi-label sound tagging
