image processing
join images (tiling)
montage a.png b.png -tile x1 -geometry +1+1 -background none out.png
create an animation from a set of frames
convert -adjoin image_*.png ani.gif
batch rename a set of files
- rename -v 's/unnamed./view_/g' *.png
- use the matched string as a variable: rename -n 's/([0-9]{4})/frame_$1/g' *.png
- here $1 gets the value of the expression within parenthesis
- zero padding of numeric filenames:
- example: 1.jpg goes to 0001.jpg
- command: rename -v 's/\d+/sprintf("%04d",$&)/e' *.jpg
Video tools
- to play a yuv file:
- mplayer -demuxer rawvideo -rawvideo fps=25:w=176:h=144:format=i420 your.yuv
- to output its frames to images:
- mplayer -vo png -demuxer rawvideo -rawvideo fps=25:w=176:h=144:format=i420 your.yuv
- to grep inside find
find -name *.xml -print -exec sh -c 'cat "$1" |grep nombre' {} {} ";"

Journal abbreviations
El otro día por fin descubrí como abreviar de manera sensata los
journals y poder cambiar de modo abreviado a completo fácilmente.
Además, está bueno para poner journals que se repiten varias veces.
Definen algo así
@STRING{ieee_trans_pami = {IEEE Trans. Pattern Analysis and Machine Intelligence}}
y luego en el el bibtex entry ponen:
@ARTICLE{segm:edge_detection:canny:86:computational_edge,
author = {J. F. Canny},
title = {A computational approach to edge detection.},
journal = ieee_trans_pami,
year = {1986},
volume = {8},
pages = {679--698},
xxxarea = {image processing}
}
Para hacer lo de las abreviaturas.
Se hace con 3 archivos bibtex. el documento común (references.bib) en
vez de la información del journal tiene una variable. luego tienen dos
documentos con las abreviaturas:
journal_list_short.bib journal_list_long.bib
entonces cuando incluyan la bibliografía, hagan esto: \bibliography{journal_list_short,references} \bibliography{journal_list_long,references}
booklets
<bash> pdf2ps these.pdf these.ps psbook these.ps these_book.ps pstops '2:0L@.82(1.045w,-2cm)+1L@.82(1.045w,0.5h)' these_book.ps these_booklet.ps ps2pdf -sPAPERSIZE=a4 these_booklet.ps these_booklet.pdf </bash>

linksys spa3000
I have 1 SPA 3k in Uruguay (let me call it node A), 1 SPA 3k in spain (node B) and another SPA 2k in spain (node C). Until last month, my (working) setup was: I succesfully set up the connection between nodes A and C. Here is a sketch of the setup:
- node A:
- hardware: linksys SPA 3k
- network: dynamic ip, with DDNS behind a linksys WRT54G router which handles DDNS.

Las cosas las instalan de 4 formas:
- appstore
- dmg bajado
- a traves de homebrew
- compilado desde fuentes
Yo trataría de instalar cada cosa en ese orden de preferencia.
development
- install xcode from the appstore
- install command line tools (to get command line gcc)
- install homebrew
- install from dmgs:
- cmake
- doxygen
- netbeans or eclipse C++
- install with homebrew:
- graphicsmagick
- compile from source:
- ITK
- OpenCV
latex
- texmaker
office
- word from downloaded dmg
- openoffice from dmg
misc
- blender from dmg
