detection

问题 I am working on detecting similarity between 2 videos in Java. The user will suggest two videos, and software has to detect whether they are similar by checking the file content. I read that it is possible to compare each frame of the 2 videos. Can anyone please share any suitable algorithms (or code or methods) that can be implemented in Java? 回答1: There is a huge variety of algorithms for determining similarity in images.

问题 I have taken out the laser curve of this image : (source: hostingpics.net) And now, I'm trying to obtain a set of points (the more, the better), which are in the middle of this curve. I have tried to split the image into vertical stripes, and then to detect the centroid. But it doesn't calculate lots of points, and it's not satisfactory at all ! img = cv2.Canny(img,50,150,apertureSize = 3) sub = 100 step=int(img.shape[1]/sub) centroid=[] for i in range(sub): x0= i*step x1=(i+1)*step-1 temp =

问题 I have detected 22 balls and am struggling to find a way to run a color detection algorithm on these circles to get their colors. I am using HoughCircles to detect the circles but don't know how to check what color these circles are? Source Code: #include <stdio.h> #include <cv.h> #include <highgui.h> #include <math.h> int main(int argc, char** argv) { //load image from directory IplImage* img = cvLoadImage("C:\\Users\\Nathan\\Desktop\\SnookerPic.png"); IplImage* gray = cvCreateImage

问题 So I have real time video stream. With 1 (one) person on It . It Is Black and White, I need to be able to capture this persons eyes and mouth (direction (at least X,Y), state (at least opened or closed) ) So Is there any fast library(s) for finding human eyes and mouth in Flash in such case? (pure Actionscript or Haxe\Java\C++\C port in SWC form...) What do I know Is - some libs are described in this presentation http://www.bytearray.org/?p=1040&cpage=1#comment-330183 Grate example for eyes
