Application Examples

Germination detection

Roots emerging from seeds were detected by SeedAIxpert and marked in yellow. Germination percentage (seeds with / without roots in relation to total seed number) is provided. Detected roots can be measured, e.g. root lenght.

Germination detection of coated seeds

SeedAIxpert is designed to work with coated seeds, too. Here coated seeds were classified as germinated or not germinated according to the occurence of roots. As SeedAIxpert can work with color analysis, it can handle differently coated seeds at once.

SeedAIxpert works with most seeds

SeedAIxpert technology is able to cope with seeds of different sizes and colors. No matter whether you work with small herb or vegetable seeds or with maize, SeedAIxpert makes seed testing easy.

Artificial intelligence for seedling classification

Emerging seedlings consist of various parts, e.g. roots, shoots, or root hairs. With machine learning algorithms, SeedAIxpert can be trained to recognize each of these parts separately.

Maize germination

Example for a maize germination test as top-of-paper assay. SeedAIxpert images the samples and derives germination quality data from the images.

Vegetable seed germination classified with machine learning

Vegetables germinating in a top-of-paper test were classified with the SeedAIxpert machine learning algorithms. Occurence and size of shoot and root are analyzed and a subsequent quality rating, e.g. as usable plant test can be set up.

Seed classification

Embryo and Endosperm are visible on the surface of maize seeds. Imaged and classified by SeedAIxpert, fractions of embryo and endosperm are measured for each seed.

Seedling emergence test

Oilseed rape germination was assessed in a seedling emergence test with seeds placed in substrate. Emerging cotyledons were recognized and measured for germination frequency and seedling quality.
