abstract = "Driven mainly by the modern advances in the Earth Observation
technology in the last years, the increase of the remote sensing
data volume represents a new challenge. The current available
image processing solutions fail to deliver the expected
performance and scalability required to deal with this large
volume of data. Aiming to face this problem, the authors proposed,
in a recent work, a distributed strategy for region growing
segmentation of arbitrarily large images. The presented strategy
is able to perform in cloud-computing environments and most of the
distributed architectures. The original implementation is based on
the MapReduce model, which offers a highly scalable and reliable
framework for storing and processing massive data in cloud
computing environments. However, MapReduce is losing popularity
lately and it is being slowly replaced by different engines that
have been emerged. Since the distributed image segmentation is a
method independent from its implementation, this paper aim to
compare the original implementation using MapReduce to a new
implementation using a different distributed framework. In this
work, the new implementation is based on Apache Tez. Tez enhances
the MapReduce paradigm by improving its speed while maintaining
MapReduce''s ability to scale to petabytes of data. The
experiments carried out on a virtual cluster in a commercial
cloud-computing infrastructure demonstrated that both
implementations present a potential scalable and efficient
solution, with Tez achieving a better performance.",
