MS Thesis
The title of my dissertation was 'Decimation Free Directional Filter Bank
for Medical Image Enhancement' It presents a new directional analysis
tool namely decimation-free directional filter bank with application to
medical image enhancement, and its comparison with directional filter
bank. Outputs of directional filter bank are maximally decimated (smaller
in size) due to the presence of decimators. Multi-rate identities are
used to push all these decimators to the right of filters. By doing so,
frequency scrambling produced in directional filter bank due to non-
diagonalization of overall downsampling matrix is removed. No
interpolation prior to image enhancement is required in decimation-free
directional filter bank, as it was mandatory step before enhancement in
directional filter bank. Artifacts produced due to interpolation can be
misleading in situation like medical images, and aerial images. These
artifacts are avoided in decimation-free directional filter bank as it
requires no interpolation. Artifacts produced due to aliasing and folding
during downsampling were also avoided in decimation-free directional
filter bank due to absence of decimators. Synthesis in decimation-free
directional filter bank at any stage, it can be achieved by just simply
adding all the images, as it was not the case with directional filter
bank. The outputs of Decimation-Free Directional Filter Banks are
combined on the basis of block-by-block 'Directional Energy Estimation'
to construct enhanced image.
