How AcuSeek works

Based on a Large Multimodal Model (LMM), images and their corresponding natural language descriptions are mapped to a shared high-dimensional vector space. This enables versatile functionalities, such as open-ended text-to-image search, image-to-image search, and alarm triggering based on the presence of persons, vehicles, objects, events, or locations.

How AcuSeek works

Search by text

Search by text

AcuSeek NVR supports natural-language-based video/image retrieval applications, allowing second-level retrieval on target images by inputting phrases or words.

Search Broadly: Supports both high-frequency object searches in security scenarios, such as cars and non-motorized vehicles, and feature-based searches for specific objects or unusual activities.
Search Instantly: Provides second-level search results.
Search Accurately: Extracts features from images and aligns them with key semantic features from the search language to achieve high-precision search results.

Bridging text queries and visual matching

Intelligent video search

Step 1:

AcuSeek identifies objects associated with a specific feature (e.g., an Audi car) or another object (e.g., a black backpack) by analyzing video footage and user-defined criteria such as time and location.
Step 2:

AcuSearch then pinpoints a specific object (e.g., a grey Audi SUV) across all scenes, providing a timeline of its appearances and related footage for further check.
