To See Clearly using Fuzzy Vision:
This work involves segmentation of images using fuzzy models. Planned are methods for pixel, edge and region-based schemes, that use several fuzzy clustering models.

In a political gerrymander, some elected politicians
represent electorates with huge populations,
while others represent electorates of small population.
In image analysis and in image engineering,
there is a process that is very much akin to holding an election,
it's called code book coding, and is also known as vector quantization.
In this process, image blocks, typically 4x4, which are called vectors,
are labelled with the like blocks (= code vectors)
of a code book.
In other words, each block in an image is represented by a particular block in the code book,
When things go well,
the code book vectors are pretty
representative of the population, but not always.
Someimes some code book vectors represent many members of the
population of vectors, while some represent just a few
r none at all;
in other words, a gerymander applies.
