###########################
model de treball tesis ::: segui tot aquest document file:///usr/share/doc/opencv-doc/ref i anar-lo estudiant ampliant ... etc ... pensant posibles aplicacions en l'art ... a fons i molt ben documentat
mirant tambe aqui file:///usr/share/doc/opencv-doc/papers per ampliar i altres documents a la xarxa
###########################
en tots els objectes ... en la funcio pdp_opencv_elquesigui_process fer un case "PDP_IMAGE_YUV" o el(s) que sigui i cridar pdp_llconv per a despres poder cridar pdp_opencv_elquesigui_process_rgb ...
pdp_opencv_motempl.c
s'han de fer variables alguns parametres que ara mateix esta cm a constants::
const double MHI_DURATION = 1;
const double MAX_TIME_DELTA = 0.5;
const double MIN_TIME_DELTA = 0.05;
const int N = 4;
tambe lo gran que vols el cercle (la variable magnitude li diu ell) ... lo ideal seria que aquesta fos relatica a la cuantitat de moviment ... no? ... (comp_rect.width + comp_rect.height) ... fes una cerca de "reject very small components" per trobar el lloc exacte on esta tocant aixo ...
i fer que ens els outlets ens doni ... x,y,heigh,width,angle de cada un dels componoents ...
aqui hi ha algo de info sobre com funciona aquest exemple
file:///usr/share/doc/opencv-doc/ref/opencvref_cv.htm#cv_motion_motempl
basicament veig que usa cvUpdateMotionHistory - cvCalcMotionGradient - cvSegmentMotion - cvSetImageROI - cvCalcGlobalOrientation -
s'ha de fer que les dades dels "blobs?" surtin per algun outlet !!!!
veure si les etiquetes es mantenen ... al primer cop que ho fas hauries de anomenar cada un dels blobs, als seguents simplement afegirlo a la llista de la sortida possiblement substituintla per i(numero de blob)
afegr el parametre apperture size al pdp_opencv_laplace :: http://www.cognotics.com/opencv/docs/1.0/ref/opencvref_cv.htm#decl_cvLaplace
