matlab - How to transition from a prerecorded video to real time video? -


i have come algorithm on matlab, permits me recognize hand gestures on prerecorded videos. now, run same code real time video time, not sure how after putting these 2 lines:

vid=videoinput('winvideo',1);

preview(vid);

(real time video on)

i thinking loop : while video on, snap repeatedly images in order analyze them.

for k=1:numframes

my code applied here.

so, know how make transition prerecorded videos real time video.

your in appreciated!

i suggest first verify whether can perform acquisition + gesture recognition in real-time using algorithm. that, first read video frames in loop , render or save them , compute reading , rendering overhead of single frame t1. compute time taken algorithm process 1 image t2. throughput(no. of frames process per second) of system be

throughput = 1/(t1 + t2)

it important know how many frames need process gesture. first, try compute minimum no. of images need identify gesture in given time , verify in real-time whether can process same no. of images in same time.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

php - Nothing but 'run(); ' when browsing to my local project, how do I fix this? -

i added new project. made mistake in projectname.conf file in sites-available apache2, led me reinstalling apache2. after reinstalling , re-enabling projects on every page of every project .. <body> run(); </body> .. i've run composer update, restarted service, restarted pc, checked config files, tried disabling new project. there nothing in error log, , access.log: 127.0.0.1 - - [15/may/2015:01:40:47 +0200] "get / http/1.1" 304 181 "-" "mozilla/5.0 (x11; ubuntu; linux x86_64; rv:38.0) gecko/20100101 firefox/38.0" maybe i'm forgetting apache2 reinstall? don't think did different last time installed it. looks haven't setup php correctly. take @ this great guide , maybe you're forgetting link php config apache2.
