Laboratory Imaging (LIM) is a technological company focused on continuous innovation in software imaging. The main development focus is aimed at general microscopy, material science, forensic science and cytogenetics.

Advanced algorithms

There is a large need for many special algorithms in the imaging software. For example: processing of the z-stacks of images (auto aligning of the sequence, extended depth of focus), stitching of images, various auto-shading and background subtraction methods. Bayesian classifiers are used in different applications such as karyotyping or classifier. Text recognition is used in a special ICAO reading module. We have also developed special methods for autocalibration and in-software elimination of geometrical objective distortion on a real time live image.

 

Special hardware implementation and construction

LIM implements hardware at the top performance level. Starting with the first PC grabbing boards from Matrox in the late 1980s, up to todays high performance cameras, stages, z-drives, motorized microscopes, filter wheels, shutters, monochromators, lasers and spectrometers.

We also provide custom-made hardware, composed of various OEM components. We have produced several spectral scanners for document analysis, motorized fiber finders and customized adaptations. We were one of the first companies in the second half of 1990s using the liquid crystal tunable filter for capturing color images using a monochrome camera.

 

Virtualization methods, Extended file formats

Virtualization methods record maximum information about the examined object and keep the data in an interactive form in a single computer file. For example, the virtual slide format – VSL - enables to store the full microscopic slide scanned with high resolution objective and in several focus levels. It enables to "virtually focus" through the sample any time later. The size of the virtual specimen goes up to several GB.

Our ND2 file format enables to record the live cell experiment into one file keeping all requested metadata, including e.g. the emission filter spectral characteristics for each channel.

The ND2 file format can also be used for bullet virtualization and it enables to make a full bullet and cartridge case scan. The virtualized object can then be examined at different angles of illumination whenever it is needed.
