Rock sorting solution was developed classifying different mine-specific types of minerals based on multi-scale color and texture features. The final solution was validated to perform better than human geologist labeling identical rock images.

Gender recognition was built with perClass to discriminate males and females based on a single face image. The solution may be deployed with perClass Runtime both to PCs and to ARM-based systems such as Raspberry Pi.

Group of prof.Nick Ramsey at Utrecht Medical Center uses perClass to classify mental states of paralyzed patients. Their Brain Computer Interface (BCI) serves as a platform for research of neurological processes

Leiden University Medical Center (LUMC) researchers used perClass to develop a novel method for automatic segmentation of join replacement scans. Contrary to traditional, manually-tweaked image analysis algorithms, their solution learns to classify different anatomical structures using systematic pattern recognition approach. Read the publication in the International Journal of Computer Assisted Radiology and Surgery.

In the Max Planck Institute of Biophysics cutting edge research is performed on neuronal organization in the mouse olfactory system. The researchers aim to describe the axonal wiring of olfactory sensory neurons in the living brain, using a combination of genetics approaches, in vivo imaging and behavioral studies on gene-targeted mouse strains.
"For analyzing our high content methods for profiling neuronal gene expression patterns in 3D we chose perClass Matlab Toolbox to aid in building sophisticated models that find patterns unnoticeable to the human biologists. Marrying the latest in high throughput screening methods with custom analytical pipelines built with perClass Toolbox lets us ask questions previously outside grasp of molecular biologists." -- Dr. Bolek Zapiec

Advanced Medical Diagnostics (AMD) has brought to market a new generation of cancer-detection ultrasound technology, providing physicians with clinically-meaningful visualization of prostate cancer.
"We use perClass to train our tissue characterization algorithm, that is to train a statistical model to detect abnormalities in ultrasound data taken in clinical setting. We work with huge data sets and dozens of features, and perClass is able to handle them without performance issues or glitches. The interactive visualization tools provided by perClass allow us to explore our feature space and understand how separation could be achieved. We work often with the k-NN classifier and we enjoy the wealth of options to configure the classifier and experiment with various implementations of the k-NN. On top of perClass we use the consultancy and training services provided by PR Sys Design. They are always delivered in the most professional way and allowing us to expand significantly our knowledge in pattern recognition as well as in the perClass library itself." -- Dr.Dror Nir, CEO

Noldus is a market leader in behavioral research, providing solutions to study both human and animal behavior. Noldus is leveraging perClass for development of robust detectors and discriminants.
"We use perClass to build models s for rat behavior detection. I especially enjoy the metadata functionality and the interactive visualization where you can view subsets based on the metadata. It gives me insight in the data, and tells me what is feasible. Therefore, it saves me the time I would otherwise spend on useless efforts to optimize what is beyond reach. Also, I find the documentation and support really good!" -- Elsbeth van Dam, R&D Noldus
Update Jan 2014: Pattern recognition algorithms, investigated during our joined project, are now part of the EthoVision XT software.

DebTech, a company within the DeBeers mining group, developed their R-Sputnik particle characterization system using perClass. The system captures silhouette images of particles and generates 3D models of the particles.
"Using perClass we have implemented a classifier that takes in various features extracted from these 3D particle models and classifies them into a number of shape categories that are of relevance to us. The system also allows us to take simultaneous reflectance image of each particle. Relevant data from these images is fed into another classifier that enables us to obtain a colour classification for each particle." -- Dr. Garry Morrison, DebTech

For Type22 (now part of SITA) perClass designed robust classification algorithms and embedding in their baggage handling solutions, minimizing the deployment time.
"With perClass we have been able to apply our classification algorithms to a variety of "real-life" baggage handling products. perClass development environment is easy-to-use, powerful and extensive. Deploying the created algorithms is simple and reliable." -- Jorick Naber, Type22 BV
