Systems for Seed Analysis and Measurement
Our product portfolio is based on proven optical measurement technologies for precise seed analysis.
Depending on application, sample volume, and required analysis depth, our systems are available in different configurations and sizes.
All MARViN systems are delivered as fully integrated measurement solutions.
The software is an essential part of the system architecture and is required for system operation, data acquisition, and evaluation.
Measuring Methods
MARViTECH systems are based on different optical measurement principles, selected according to the analytical requirements of the application.
Backlight Silhouette Scanning vs. Overhead Color Scanning
Backlight silhouette scanning focuses on precise measurement of seed size and shape based on high-contrast contours.
Overhead color scanning extends the analysis by evaluating color, brightness, and pixel-based information for advanced classification and impurity detection.
Systems optimized for reliable counting, size, and shape analysis across different sample volumes and throughput requirements.

Comprehensive Object Analysis
Technology & Measurement Principle Backlight Silhouette Scanning (BSS)
Backlight silhouette scanning is an optical measurement method based on high-contrast image acquisition. Objects (Seeds) are illuminated from below, creating a clear silhouette that allows precise detection of individual objects independent of surface color or texture.
This measurement principle enables reliable object counting and supports the calculation of the thousand kernel weight (TKW) based on statistically representative sample data. Seed size is determined by measuring length, width, and projected area, providing a detailed characterization of the sample.
In addition to individual object measurement, the system evaluates size distribution within the sample, supporting quality assessment and batch comparison.
Image-based filtering algorithms allow the exclusion of dust and small debris, ensuring robust results even with heterogeneous material.
For semi-transparent objects, brightness analysis can be applied to support additional differentiation within the sample.
Key Capabilities
Object counting and calculation of thousand kernel weight (TKW)
Seed size measurement (length, width, projected area)
Size distribution analysis within the sample
Image-based filtering of dust and dirt
Brightness analysis of semi-transparent objects
Application Scope
Backlight silhouette scanning is well suited for laboratory and production environments where reliable counting and geometric characterization of free-flowing seeds are required. The method provides reproducible results across a wide range of seed types and sample volumes.

Technology & Measurement Principle Overhead Color Scanning (OCS)
Overhead color scanning is an optical measurement method based on top-down image acquisition under controlled illumination conditions. Seeds are imaged from above, enabling pixel-based analysis of color, brightness, and surface characteristics.
This measurement principle supports precise object detection and counting while extending the analysis beyond geometric parameters.
Color information and brightness values are evaluated to enable advanced differentiation, classification, and impurity detection within the sample.
In addition to individual object analysis, the system allows statistical evaluation of color distributions and supports the identification of foreign material or deviations in seed appearance. Image-processing algorithms ensure reproducible results across varying sample compositions.
Key Capabilities
Object detection and counting
Color and brightness analysis
Classification based on pixel-level information
Detection of impurities and foreign material
Statistical evaluation of color distributions within the sample
Application Scope
Overhead color scanning is well suited for applications requiring advanced visual analysis, such as seed classification, quality grading, and impurity detection.
The method is applicable in laboratory, research, and production environments where color-based evaluation is essential.
