Generating events for gesture-controlled websites

问题 I am very happy that I got the opportunity to work on a website that is gesture-based. I have a few inspiration for this: link I visited lot of websites and googled it, Wikipedia and gitHub also didn't help much. There is not much information provided as these technologies are in nascent stages. I think I will have to use some js for this project gesture.js (our custom javascript code) reveal.js (Frame work for slideshow) My questions are how come gestures generate events, how does my

Two webcams on one usb 2.0 hub - works in windows but not linux

由 牧云@^-^@ 提交于 2019-12-06 15:27:31
The openCV code below grabs simultaneous images from two cameras. It works fine in windows, with the cameras both attached to one usb 2.0 hub. When I try the same code in linux, it only has enough bandwidth for one camera at a time. I've also tried viewing the two streams at once with guvcview, same issue. What I need is some way to force the webcams to work together, possibly by setting the amount of bandwidth the driver requests. capture = cv.CaptureFromCAM(0) capture2 = cv.CaptureFromCAM(1) while True: frame = cv.QueryFrame(capture) frame2 = cv.QueryFrame(capture2) cv.ShowImage("w1", frame)

Webcam DirectShow Properties Page in Python

由 末鹿安然 提交于 2019-12-06 13:30:20
I'm working on a windows Python 2.7 application that needs to communicate with many different USB webcams. I have been using OpenCV, but for some scientific webcams, the default frame rate, capture format, etc. aren't detected and I get only a blank image. An external program that can open DirectShow properties pages can fix this in my program, but I'd like to have this feature in my application. I have tried one available Python library to do this: VideoCapture (http://videocapture.sourceforge.net/). While this opens property pages, it doesn't allow changing any device settings ("Error

问题 I'm developing on Processing 2.0b, and i just bought a C920 logitech webam for a good capture quality. Then I try to capture at 1920 x 1080 , the problem is that I'm under 15 fps per seconds.. When I list all the devices availsable to capture, the program write: Some size and fps ... -[61] "name=HD Pro Webcam C920,size=1024x576,fps=5" -[62] "name=HD Pro Webcam C920,size=1024x576,fps=30" -[63] "name=HD Pro Webcam C920,size=1280x720,fps=5" -[64] "name=HD Pro Webcam C920,size=1280x720,fps=30" -

问题 Have an AVI videofile, and a webcam. cvQueryFrame returns null in both cases. Code is applied(only for cam): #include "highgui.h" #include <iostream> using namespace std; int main( int argc, char** argv ) { cvNamedWindow( "KillCam", CV_WINDOW_AUTOSIZE ); cvWaitKey(0); CvCapture* capture = cvCreateCameraCapture(-1); assert(capture != NULL); IplImage* frame; while(1){ frame = cvQueryFrame( capture ); if( !frame ) break; cvShowImage( "KillCam", frame ); char c = cvWaitKey(33); if( c == 30 )
