Data Annotation Services

Data annotation is crucial for developing effective machine learning and AI systems. EXELLIGENT Infotech offers comprehensive data annotation services tailored to meet the specific needs of various industries.

Overview

Our data annotation services ensure that your data is accurately labeled and ready for use in training and validating machine learning models. We specialize in annotating images, text, audio, and video with precision and efficiency.

Image Annotation

We provide precise labeling for images used in applications such as autonomous driving, medical imaging, and retail analytics. Techniques include:

  • Bounding Boxes

    Drawing boxes around objects to help AI models detect and recognize them.

  • Semantic Segmentation

    Dividing an image into segments where each pixel is classified into a category.

  • Landmark Annotation

    Marking key points on objects, useful in facial recognition and pose estimation.

Text Annotation

Our text annotation services include tagging and categorizing text for natural language processing tasks such as sentiment analysis, entity recognition, and chatbot training. We offer:

  • Named Entity Recognition (NER)

    Identifying and classifying entities like names, dates, and locations within text.

  • Sentiment Annotation

    Labeling text to reflect sentiments like positive, negative, or neutral.

  • Intent Annotation:

    Tagging text to indicate the intention behind user queries, useful for chatbots and virtual assistants.

Audio Annotation

We provide detailed transcription and tagging of audio files to enhance speech recognition, audio analysis, and voice assistant technologies. Services include:

  • Speech-to-Text Transcription

    Converting spoken language into text.

  • Speaker Diarization

    Identifying and distinguishing between different speakers in audio files.

  • Sound Event Detection

    Labeling specific sounds or events in audio recordings.

Video Annotation

We offer advanced video annotation for tasks like object tracking, action recognition, and event detection. Techniques include:

  • Frame-by-Frame Annotation

    Labeling objects in each frame of a video.

  • Temporal Segmentation

    Dividing video into segments based on events or activities.

  • Pose Estimation

    Marking human poses in video for applications in sports analysis and motion capture.

Use Cases and Examples

Autonomous Vehicles

Annotating images and videos to train AI for obstacle detection and navigation. Example: Labeling road signs and pedestrian locations in driving footage to help self-driving cars recognize and respond to their environment.

Healthcare

Labeling medical images like X-rays and MRIs to assist in diagnostics and treatment planning. Example: Marking tumor boundaries in radiology images to help radiologists and AI models detect and assess tumors accurately.

Retail

Enhancing product recommendations and inventory management through image and text annotation. Example: Tagging products in images for e-commerce websites to improve search results and recommendations.

Security

Annotating video feeds for surveillance to detect and respond to suspicious activities. Example: Marking people and vehicles in security camera footage for monitoring and threat detection.
