Abstract
Camera-based character recognition has a possibility to realize a variety of applications and has been
paid attention. However, character images are often taken from different angles and characters tend to be distorted.
In such a case, recognition accuracy becomes worse. Therefore, we must find some methods to deal with this
problem. In this paper, we experimentally evaluate some affine-invariant local descriptors by testing how well
they can recognize affine distorted characters. As a result, affine-invariant local descriptors are robust to affine
distorted characters to some extent.

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.
