Resumo
This study aims to optimize runtime performance of a system developed to aid
the diagnosis of childhood pneumonia by computer. This system, called Pneumocad
according Macedo (2012), aims to identify chest radiographs consistent with the disease
using computational techniques for recognizing patterns in textures through
decomposition of the transformed wavelets, features extracted from the decomposition
and classi cation applied to radiographs. In pursuit of this optimization in
terms of performance at runtime, insertion of new rays and the recovery of their
radiographs similar, we used the proposed deployment of a cluster architecture of
radiographs already stored in the database Pneumocad. In parallel , functionality,
responsible for de ning how a radiograph is similar to another , were transferred from
the source code Java to views in the database. The experiments were performed on
databases that contained 183, 2.568 and 10.200 radiographs and using the Pneumo-
cad of Macedo (2012) , the Pneumocad Optimized with views and without grouping
and Pneumocad Optimized with views and grouping. The experiments and results
show that the proposed optimization contributed to the evolution of Pneumocad and
enhanced this tool to support the diagnosis of pneumonia in childhood.
