Big data analytics which leverages legions of disparate,
structured, and unstructured data sources is going to play
a vital role in how healthcare is practiced in the future.
One can already see a spectrum of analytics being utilized,
aiding in the decision making and performance of healthcare
personnel and patients. Here we focused on three areas of
interest: medical image analysis, physiological signal processing, and genomic data processing. The exponential growth of
the volume of medical images forces computational scientists
to come up with innovative solutions to process this large
volume of data in tractable timescales. The trend of adoption
of computational systems for physiological signal processing
from both research and practicing medical professionals
is growing steadily with the development of some very
imaginative and incredible systems that help save lives.
Developing a detailed model of a human being by combining
physiological data and high-throughput “-omics” techniques
has the potential to enhance our knowledge of disease states
and help in the development of blood based diagnostic
tools [20–22]. Medical image analysis, signal processing of
physiological data, and integration of physiological and “-
omics” data face similar challenges and opportunities in
dealing with disparate structured and unstructured big data
sources.
Medical image analysis covers many areas such as image
acquisition, formation/reconstruction, enhancement, transmission, and compression. New technological advances have
