Abstract
Character detection in scenery images is a very difficult
task. This paper describes a strategy of selecting character
patterns for easier detection in scenery image. These
character patterns, called conspicuous character patterns,
are selected from character font sets according to a criterion
that evaluates how the font has a larger distance from
a non-character pattern distribution and, simultaneously,
with a smaller distance from a general character pattern
distribution. Qualitative and quantitative evaluations have
been made to observe how the selected fonts are more conspicuous
than other fonts.

Format definition
Edits apply immediately and stay in effect until you pick a style again or reset. First line is the default; add lines like "book: …" to override per type.
How to write the definition
Insert a field with braces like {authors}. A part enclosed in [ ... ] is omitted entirely when any field inside it is empty. Available fields:
One macro per line as \name{field}{field}…. A field name in braces is replaced by its (LaTeX-escaped) value; other text is kept. Rename macros or add lines freely — they appear in the macro selector. A line like master_thesis: thesis fixes the macro for a type (automatic choice: journals use paperdoi with a DOI, paperno with a number, else paper; conferences conf with pages, else confpaper; books book). {pages} comes as 119--124; {journal} falls back to the book title.
