Research, Development & Quality Control

LemnaTec systems are used across the world in hundreds of different research and quality control applications. LemnaGrid, one of the modules in the LEMNATEC-OS software suite, contains a variety of functions that allow you to isolate and extract selected features from digital images.

Below, there are application use cases together with technical tutorials. The use cases refer to how the LemnaGrid phenotyping software has been successfully applied in plant measurements. The technical tutorials aim at supporting users in estabilshing analysis procedures with LemnaGrid.

In addition, the LemnaTec Academy offers workshops and training courses to support a wide range of phenotyping disciplines, as well as consultancy packages to assist with phenotyping projects. For more information contact us now at Enable JavaScript to view protected content.

An analytic approach to evaluate Near InfraRed (NIR) data from plants under stress conditions

A Comprehensive Approach to Assess Arabidopsis Survival Phenotype in Water-Limited Condition Using a Non-invasive High-Throughput Phenomics Platform. Front Plant Sci. 2015 Dec 15;6:1101

Partitioning turf images

Region-based feature extraction focuses on the local distribution of low level features such as colour and texture.

Wheat Ears Segmentation

This process may be used to propose the development stage of the wheat by analysing the size of the ears.

Calculation of daily water consumption and water use efficiency

Temporal dynamics of maize plant growth, water use, and leaf water content using automated high throughput RGB and hyperspectral imaging.

Processing Multiple Images with Batch Maker

In the fifth part of our series we will build another grid application to measure leaf angle in corn but use another grid device. Specifically we are going to estimate the leaf insertion angle at different local points along the leaf skeleton line and thereby use Batch Maker to simplify the multiplication of processing streams.

Corn Leaf Segmenter

LemnaGrid can create a topological skeleton from a shape. This allows us to split an imaged plant into its larger constituents: leaf/branch and stem.

HSI to grey converter

The ‘HSI to grey converter’ is a useful LemnaGrid tool to convert an RGB image into a more human intuitive color appearance system, i.e. the hue-saturation-intensity (HSI) model.

Image Processing with ImageMagick, ImageJ & R/EBImage

The functionality of LemnaGrid can be extended interacting with external image processing applications. In this short post I am going to show how three different external programs (ImageMagick, ImageJ, R/EBImage) can be embedded into the LemnaGrid workflow to perform fast fourier transform

Image Inverter & Image Adder

Given a reference image we can spot an object in a sample image by image comparison, aka image subtraction. In this paper we show you how to apply image subtraction with LemnaGrid for image segmentation.
