All functions – graphically represented by boxes – can be combined on a surface by aligning the boxes to workflows. Along such workflows, each function can provide insight in the progress of the analysis by feeding out an intermediate image. Image processing workflows can include branches and parallel paths that combine to a final result. LemnaGrid extracts a wide selection of relevant features out of images recorded with different sensors and derives phenotypic parameters relevant in plant research, breeding, environmental studies, seed testing, toxicology, and more. Besides RGB, LemnaGrid can process images coming from many camera types such as chlorophyll fluorescence, hyperspectral, multispectral, or (near-)infrared cameras. Moreover, images of luminescent or fluorescent reporters in genetic and physiological assessments can be processed. LemnaGrid analytical software enables extraction of information from all recorded images and scans. The image and scan data, together with comprehensive metadata, are stored into a file system or data base, and are accessible for retrieval for analysis. LemnaTec software always stores the unprocessed original data coming from the cameras, so that users can access these for documentation, quality control, or re-assessments. All subsequent image processing is documented, so that all steps of the analyses are transparent.
