The bit that's giving me issues is the "calculatedetails" function, where an mp3 file is opened in binary and then an array of chars is filled with the binary data.
The problem I'm having is that I want to be able to read the constituent bits of the characters in, so that I can find the mp3 frame headers (12 1's in succession)
I'm aware that the section I've added in to perform this is incorrect.
I m trying to read a video frame by frame through a c program for which i need to know the format of .wmv (native video file for windows) file,can i get it??
I want to show a frame of a gif image. I searched and found that the following code should work, but it doesn't work. it detects the number of frames correctly but it shows the whole frames of gif instead of the specified frame.
Image[] frames = new Image[36]; Image GG = Image.FromFile(@"C:UsersAdministratorTEST C#TEST2frame2chef.gif"); FrameDimension dimension = new FrameDimension(GG.FrameDimensionsList[0]); // Number of frames int frameCount = GG.GetFrameCount(dimension); label1.Text = frameCount.ToString(); // Return an Image at a certain index GG.SelectActiveFrame(dimension, 1); frames[1] = ((Image)GG.Clone()); pictureBox1.Image = frames[1];
I m trying to place an image on the colour frame of the Kinect live video. I m able to overlay the image using alpha blending mechanism.
The image used is a bitmap image of dimension 128*128.
The Kinect has a resolution of 640*480.
IDE used is Visual studio 2010 and I m developing using c++.
The Kinect has a render target whose size is taken as 640*480 so that it stretches for the complete window. So when I try to overlay the image it appears 5 times because of this stretching. If I increase the image size to 640*128 i get a single image that is stretched horizontally across the window with dimension 640*480.
I have created a function that will create a render target with bitmap properties and size equal to 640*480. This is used to store the data from the Kinect, frame by frame, and draw it on to the screen
So I think when I overlay the image, it gets replicated 5 times to meet the render target size.By default the image is placed at the left top position.
My doubts are
- How can I use different functions to specify the size of render target for Kinect as 640*480 and the size of render target for bitmap image as 128*128.
- How to I give overlay or place the image on the live video at a specific location.
This code will show the data from the .txt file "file1" the data is (0.0 0.1 0.2 0.5 0.8 0.9 1.0)
What I'm trying to do is take these float values and add them all up and divide them by 7 (finding the average and output that) Convert it into a percent and print it in a field:
Width of 6 with 2 digits after the decimal point...
I tried doing something like cout << "the average is: " << data/7 << endl; but that didn't work. I got an error that said "/" was not an operator.
Code: #include <iostream> #include <fstream> #include <string> using namespace std; int main() { ifstream myfile("file1.txt"); string data; getline (myfile, data); cout << data << endl; myfile.close(); return 0; }
what I'm trying to do is output a certain string depending on the color I see in the video feed. For right now, what I've done is threshold the feed so that everything above a certain brightness shows up as Red. Now I want to have something that says if there's any red in the feed, then I output a "1" to a text box on my user interface that's showing the feed. If there is no red, then I output a "0" to the text box.
I'm using Emgu CV C ++ with VS2010.
This is the code I have so far that isn't working correctly, it's giving me a compiler error.
Essentially what I need to do is take a text file, ("input.txt"):
4 4 1 0 0 1 1 1 1 1 0 0 1 0 0 0 1 0
And take the first two values on line 1 (4, 4) and use them as length and width. Number of rows: 4 Number of columns: 4
Then I need to print out the matrix and further manipulate it. I need to find the sum of the 1's per column and then take that number and replace each 1 with the 1's in each column.
The part that's mostly troubling me is that my instructor will be giving me the input file with random values, so I don't know what the matrix dimensions will be.
I can read the 2D array but can't seem to use it after. I need to find a way to skip the first line, and then read in the matrix and be able to use it mathematically to add up each column.
I'm trying to add a function now that lets the user open 1 or more files and import them to the database and dataGridView. Now the way it is now (should) work. But when it has finished with FILE1, it won't add FILE2 as it then gives me an error that the Column Date Already exists.
Now I can fatch all the excel sheet belongs to the Excel File.But How can I check "If and Only If the sheets are havin Underscore in their name(eg. student_data,teachers_data) then only the data of the sheets will populate in tha data base"
1. Write a program the calculates the volume of a sphere.
Use a define to set Pi to 3.14 and a macro for the formula for the sphere. V = 4/3PiR3. In main ask for the radius (R). Pass it to a function where you calculate the volume and return it to main and print the volume in main. Use float values. (Save this program as you'll need it later.)
I have a piece of code in C with header files included. I run it on Mac OS X Maverick with XCode 4.6.2 installed. GCC is also installed. Note that Command Line Tools in XCode are already installed.
When I compile it, the error I receive says something like this:
add.c:1:19: error: stdio.h: No such file or directory add.c:2:20: error: stdlib.h: No such file or directory add.c:3:20: error: unistd.h: No such file or directory
However when I run it on Ubuntu, it compiles without a problem.What to do?
So I've been making a header file and put variables in their own namespace to avoid conflicts. My question is, do functions in the header file normally go in a namespace too, or should they just be named in a way which makes them unlikely to be accidentally copied?
I have a class Myclass (for the sake of the example). I have a header file 'space.h', which is following:
#include "Myclass.h" struct Files {Myclass* new_object, int number};
But turns out in the Myclass.h, I need the struct Files, like so:void function(vector<Files> arrangement);
So I would have to include "space.h" in the Myclass.h, but this way there's going to be a double definition of struct Files, since Myclass.h includes space.h and space.h includes Myclass.h.
My teacher talks about header files just having definitions and not declerations. I am writing a program that has a .h file and a related .cpp file along with a main.cpp it would be nice to have the .cpp file associated with the .h file compiled into an object file that would than just be referenced when the .h file is included. Am I making any sense?
