perClass on Raspberry Pi
We're happy to announce an experimental port of perClass Runtime to Raspberry Pi (ARM Linux, $25 credit-card size computer). It allows developers to quickly deploy any classification algorithm, trained in perClass, to Raspberry Pi devices.
This opens an entirely new set of possible applications ranging from face and person recognition (gender, age), person identification to robot vision tasks.Read more...
YesDelft network event
The annual networking event traditionally provides a great opportunity to see the many developments in yesDelft companies.
We’ve got many visitors from different sectors ranging from industry (embedded, horticulture, IT) to research and educational institutions building their own smart systems with robotics and computer vision.Read more...
perClass course March 2013
In our March perClass course we welcomed eight participants from several countries including Turkey, Israel and Canada. It has been a strong group, with several participants having extensive prior experience in industrial machine learning. We had nice discussions, and were happy to exchange different views and approaches for solving recognition challenges.
As everyone was of a different nationality, we also had fun sharing our perspective ranging from food to approach to life :)
We are especially happy that several participants went home with novel or improved solutions for long term unsolved challenges. As one participant wrote: “Thanks again for the excellent course. I gained the right knoweldge to delve futher into our machine learning problems.”
Delft Robotics Institute event
On January 25th 2013 the kick-off event of the Delft Robotics Institute took place. All the robotics labs of Delft Technical University joined together showing their research results. There were robots that walk, dance, cook, play soccer; the elephant robot for playing with hospitalized kids...
We were also present, as one of the spin-off companies, demonstrating our technology. We showed two industrial quality control demos. However, general public was attracted mostly by our live gender classifier labeling faces detected by OpenCV as "male" or "female". It was fun to test the classifier on such a sensitive issue... We were quite satisfied with the classifier reliability, but you know, it was not always right :) Read more for the videos of our demo and TV coverage!
December perClass course
In the December perClass course, we welcome participants working on behavioral analysis, product inspection and service robotics applications. It was very interesting to discuss different aspects of building pattern recognition systems in their specific fields! In the second part of the week, we focused on system design issues such as experimental design, choice of features, proper system evaluation and classifier deployment. The participants explored how to apply the concepts to their own data sets.
Vision fair 2012
perClass was present also at this year 25th edition of the Vision fair in Stuttgart, the biggest machine vision event worldwide. We have enjoyed a great interest from system integrators, machine builders and industrial researchers!

perClass in use: Latest research publications
We are happy to share with you some of the recent publications made by researchers using perClass:
- Detection of mental states with brain-computer interface (BCI), studied at Utrecht Medical Center in the group of prof.Nick Ramsey. Read the article in the Journal of Clinical Psychology.
- Automatic segmentation procedure in CT scans for preoperative planning of the hip replacement, studied by Leiden Medical Center and Delft University of Technology. Read the article in the International Journal of Computer Assisted Radiology and Surgery.
- Research and applications of perClass software, formerly called PRSD Studio. Read the article in the Hans Journal of Data Mining (in Chinese).
perClass course March 2012
The last perClass course took place in our office on 26-30 March. The participants came from as far as South Africa. Some had already experience in pattern recognition and wanted to deepen their proficiency, some were new to the field. Lectures alternated with exercises, so that all could practice immediately what was learned. The participants were very interested, active, asked many questions, all in a cheerful atmosphere… as the days were passing and we were getting to better know each other the frequency of jokes increased. We had fun! Even the weather has been great, with almost a full week of sun, and those who have heard about the dutch weather know that this is very exceptional :) It has been a real pleasure for us to have such a nice group coming by! This is what some of them wrote us:
“I found the course very informative. I think you have done an excellent job in developing a logical framework, with powerful tools, for tackling pattern recognition problems. The use of examples from real problems is extremely useful in understanding the strengths and limitations of a range of concepts and approaches. Thanks again for the great course!” Garry
“The Pattern Recognition course on perClass is a good chance for us to improve our knowledges in a very challenging research area, with many real-life practical applications. The theoretical part but also the exemples and exercises helped us to have a better understanding on the pattern recognition critical issues, in order to be able to desing and generate more complex applications from different real problems. The course structure covered very well the main topics in pattern recognition, actually the main stages in a pattern recognition design. Kind greetings for you for this great chance.” Sorin
“perClass is in my opinion the Swiss Army knife of Pattern Recognition: versatile, easy to use (but not superficial), and efficient, enabling you to quickly solve your problems. The perClass course can be described in similar terms: it teaches you how to solve a large range of problems, it is not difficult to follow (but can go very deep when needed), and sharpens your skills at a high pace while at the same time leaving room for relaxed talks and a friendly atmosphere. I especially liked that the course materials, and the hands-on sessions, were partly adapted to the practical needs of the participants. I recommend both the toolbox and the course to anyone doing data analysis.” Andrei
perClass 3.2 brings image cropping and connected components
The perClass 3.2 release brings number of enhancements to our sdimage interactive visualization tool. You can now interactively crop, cluster multi-band images and identify connected components with few mouse clicks. This allows you to easily focus on relevant part of your images moving quickly to what matters: Designing better classifiers.
Vision 2011 trade fair
Last 8-10 November we have presented our perClass software suite at the Vision 2011 trade fair in Stuttgart. This is one of the largest European fair in machine vision, with exhibitors ranging from machine vision components, to complete system solutions, from software to services.
Companies and visitors came from across the globe. We really enjoyed meeting many people interested in adding more intelligence to their machine vision systems or improving performances. The general feeling is that people expect automation to deliver more. Moreover, dealing with natural objects greatly increases the challenges of automatic classification systems. People are looking for new or better solutions. Our visitors were intrigued by the possibilities of statistical machine learning in perClass. With perClass they can quickly develop their own solutions in-house, saving lot of time both in the design phase and when embedding the classifier in their application. See our new brochure.
And, by the way, thanks to all of you that came by to our stand. It was very nice to see you all in person!
