The programs in this directory illustrate geometric feature detection
as discussed in chapter6. The features detected are intersections,
end points and loops. As a preliminary step in the feature detection
process, thinning(see chapter 3) is performed. The two programs found
in this directory are:
1) showdata
2) feature
Sample data can be found in: chrdata.bm
Sample output data can be found in: chrdata.0, chrdata.1,...,chrdata.9.
SHOWDATA:
The showdata program read character data in the format of a ".BM" file,
converts it to a matrix representation and outputs the image in text mode
to the screen. Characters are on a 16x 24 pixel grid.
".BM" consist of an arbitrary number of records where each record
consists of:
byte 0x00: always 0x00
byte 0x01: ascii code of the character
bytes 0x02-0x31: data in 1 bit-per-pixel format. (i.e. Thus it takes
2 bytes to represent a row of the character matrix.)
FEATURES:
Accepts a ".BM" file as input and creates: 1) a thinned version of the
target character and 2) a version of the character consisting only of
pixels that are loop members. The original, thinned and loop member
versions are all displayed. Coordinates for intersections and endpoints
are calculated and displayed. Loop mass and the coordinates of the loop
center of mass are calculated and displayed as [mass,(x,y)].
TO Compile:
icc showdata.cpp
Usage:
showdata SourceFile
where SourceFile is the name of a ".BM" format file
(both name and extention are required)
FEATURES:
To compile:
icc features.cpp
Usage
features SourceFileName
x
where SourceFilename is the name of a ".BM" format file.
(ONLY the file name should appear on the command line
as the program will fill in the .BM extention.
Output from the program will go to both the screen and to
files SourceFilename.1, SourceFilename.2, SourceFilename,...
