[3/3] Anomaly Detection Tool (Crops Dataset)
This workflow is an efficient tool for detecting anomalies in agricultural crops, capable of automatically identifying whether crop images are abnormal or unknown. Users only need to provide the URL of the crop image, and the system converts the image into a vector using multimodal embedding technology, comparing it with predefined crop category centers to determine the image category. This tool is suitable for scenarios such as agricultural monitoring, research data cleaning, and quality control, significantly improving the efficiency and accuracy of crop monitoring.

[3/3] Anomaly Detection Tool (Crops Dataset)
Key Features and Highlights
This workflow is an anomaly detection tool based on an agricultural crop image dataset. It accepts URLs of arbitrary crop images and leverages a multimodal embedding model to convert images into vector representations. By comparing these vectors against pre-established crop category centers (medoids), it determines whether the image belongs to a known crop category or represents an anomaly (unrecognized crop).
- Automated image feature extraction and vector embedding
- Efficient similarity search using the Qdrant vector database
- Intelligent anomaly detection through configurable thresholding
- Adaptable to different crop category datasets
Core Problem Addressed
In agriculture, rapidly and accurately identifying whether a crop image is anomalous or unknown is critical for crop monitoring, pest and disease early warning, and quality control. This workflow addresses the challenge of automatic anomaly detection in crop images, eliminating the need for manual comparison and judgment, thereby improving detection efficiency and accuracy.
Application Scenarios
- Automated identification and screening of anomalous crop images in agricultural monitoring systems
- Anomaly sample detection and cleaning in agricultural research datasets
- Quality control and traceability systems for agricultural products
- Any scenario requiring category anomaly detection via image recognition, especially in crop-related fields
Main Workflow Steps
- Trigger Execution: Receive requests containing crop image URLs via the workflow trigger.
- Variable Initialization: Set parameters including the Qdrant vector database URL, collection name, and threshold values.
- Image Embedding Generation: Call Voyage AI’s multimodal embedding API to convert the input image into a vector representation.
- Similarity Query: Use the Qdrant API to query similarity scores between the image vector and predefined crop category centers (medoids).
- Score Comparison: Compare similarity scores against the threshold using a Python code node to determine if the image belongs to a known category or is anomalous.
- Result Output: Return textual feedback indicating “Similar to [Crop Name]” or “Anomalous Crop Detected.”
Involved Systems and Services
- Qdrant Cloud: Serves as the vector database storing crop image embeddings and category centers, enabling fast vector similarity search.
- Voyage AI Embeddings API: Provides multimodal image vector generation services, converting images into high-dimensional vectors.
