About Centre for Pattern Recognition
The PES Center for Pattern Recognition is involved in research projects in the ubiquitous areas of signal processing and pattern recognition. It focuses on designing mathematical and engineering tools to solve computational problems in biomedicine, biometric recognition, optical character recognition and text analytics, video processing and various applications of data mining. Thus, researchers at the Center for Pattern Recognition work at the interface of multiple disciplines including biomedicine, healthcare, mathematics and multidimensional signal processing. Assist-devices for various applications such as healthcare and education are prime-movers behind most of the work taken up at the Center. The Center is committed to the dissemination of knowledge in the core areas of pattern recognition and signal processing and related domains.
Active & Completed Projects 4
Automated diagnosis of the retinopathy of prematurity in collaboration with Dr. Anand Vinekar and his team at Narayana Nethralaya
OngoingAnalysis of retinal camera images of the eye and designing features that distinguish the image of a healthy subject from that of a subject with a retinal pathology.
Automated (re-)scheduling of surgeries in a multispecialty hospital in collaboration with Mr. Sunil Kumar C. N. and his team at Narayana Hrudayala
OngoingStudents are working on algorithms that will automate and ensure optimal utilization of resources (such as operation theatre time and surgeons) in the event of an unexpected delay or cancellation of surgery at a certain time on a certain day.
