The art of teaching machines to interpret and analyse medical images

separator

Ever since the wonder invention of microscope by Anton van Leeuwenhoek and the discovery of the X-rays by Wilhelm Röntgen, the field of medical image analysis has developed into a life saving discipline, offering previously unattained opportunities for diagnosis. Medical images have, since then, played an important role in everyday medical practice. It is even […]

Important Aspects in Smart Segmentation of Medical Objects of Interest

separator

Segmentation of object is an age old problem in computer vision. Also, it is the first step in many object recognition and tracking tasks. Image segmentation is the process of partitioning a digital image into multiple segments such that each segment make sense of the object of interest. Another view of object segmentation is to […]

Using Unbalanced Datasets for Deep Learning in Medicine

separator

Deep learning is now considered a panacea to all classification problems; especially those involving images. This is especially true of the medical diagnostic world which generates several petabytes of data each year. With today’s medicine moving to an evidence based diagnosis, this would increase every year. As such, it is a burgeoning challenge for data […]

The art of building a “continuously learning” diagnostic tool

separator

Do medical devices change? Yes, of course. Better and better new versions come out. But is the piece of equipment that you purchased two years ago any smarter today than it was then? Can it do more than what it did two years ago? That’s impossible, right? Wrong! Welcome to SigTuple, the maker of continuously […]

Examining blood smears or urine samples through automated microscopy has umpteen number of challenges, some of which were addressed in Bharath’s article on Challenges and Opportunities in Automated Microscopy. In this blog, I would like to continue by outlining many more challenges associated with automated microscopy. While examining urine samples or blood smears through a […]

The exciting new world of machine learning in healthcare

separator

The field of artificial intelligence in general, and machine learning in particular, has undergone a sea change in the last few years. The way machine learning works can be briefly summarized as follows: A parameter driven classification algorithm is formulated. This is used to derive “decisions” from “input data”. Some popular choices of classification algorithms […]
