Output is as follows. Im stumped. its numRows+2 because i am adding a border
int** mirrorFramedAry = new int *[numRows+2];
for(int i=0; i<numRows+2; ++i){

}
for(int i = 0; i < numRows+2; ++i)
for(int j = 0; j < numCols+2; ++j)
std::cout << mirrorFramedAry[i][j] << " ";
for(int row = 1; row<= numRows; row++){
for(int col = 1; col<= numCols; col++){
int value;
input >> value;
mirrorFramedAry[row][col] = value;
//if(row == 1) mirrorFramedAry[0][col] = value; //mirrors top row
//if(row == numRows) mirrorFramedAry[row+1][col] = value; //mirrors bottom row
}

You filled up the data starting from the second row and second column when you used 1 as the starting index for rows and columns in the following loop:
for(int row = 1; row<=numRows; row++){
for(int col = 1; col<=numCols; col++){
int value;
input >> value;
//cout <<value<<" ";
mirrorFramedAry[row][col] = value;
}
}
But then, you are trying to display the data starting from the first row and first column when you use 0 as the starting index for rows and columns in the following loop:
for(int i = 0; i < numRows; ++i)
for(int j = 0; j < numCols; ++j)
std::cout << mirrorFramedAry[i][j] << " ";
If you see garbage, it's because you the contents of the first row and the first column were not properly initialized.
You can fix the problem by:
Not using elements of the array that were not initialized, or
By initializing those all the elements of the array.
Your initialization loops start at index 1 instead of index 0, and go to numRows / numCols instead of numRows-1 / numCols-1
for(int row = 1; row<=numRows; row++){
for(int col = 1; col<=numCols; col++){
int value;
input >> value;
//cout <<value<<" ";
mirrorFramedAry[row][col] = value;
}
}
should be
for(int row = 0; row<numRows; row++){
for(int col = 0; col<numCols; col++){
int value;
input >> value;
//cout <<value<<" ";
mirrorFramedAry[row][col] = value;
}

I would like to print a '>' sign next to an array which is able to move up and down when different things are inputted.
I am able to print a 12x12 array of 0s but when I try to print a '>' in line 7, the '>' is inputted into the array and the row itself is shifted over instead of the array being kept uniform (i.e. the '>' must be independent to the array).
I have tried creating two arrays of the '>' and the 0s but I am not able to print two things horizontally next to each other.
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int row = 0;
while (row < 12){
int col = 0;
while (col < 12){
printf(" 0");
col = col + 1;
}
printf("\n");
row = row + 1;
if (row == 7) {
printf(">");
}
}
return 0;
}
output:

thank you !
To display a ">" sign before your matrix you can use a conditional statement specifically for the required line number.
#include <stdio.h>
#include <stdlib.h>
int main(void) {
for (int i = 0; i < 12; i++)
{
if(i == 7) // conditional statement
printf("> "); // for ">" followed by
else // a space to maintain
printf(" "); // the structure of matrix
for (int j = 0; j < 12; j++)
{
printf("0 ");
}
printf("\n");
}
return 0;

Hope it helps!!!
I have to rewrite the source code to new version of OpenCV and I have problem with functions and class cvLoad, cvarrToMat and IplImage which doesn't exist in new version of OpenCV.
My old code is:
cv::Mat load(string path) {
IplImage * imgT = (IplImage*) cvLoad(path.c_str());
return cvarrToMat(imgT);
}
I get this error output while compiling:
error: 'IplImage' was not declared in this scope
The data which are loaded are depth maps from UTKinect 3D dataset.
Here is example of xml file:

I'm currently writing a function that will manipulate a 512x512 .BMP image and I'm struggling with reading in the pixel data. I'm including fstream in this to deal with reading the image data.
My function should work explicitly with 8-bit Grayscale .BMP images, so I really shouldn't need to worry about the file Headers. You can see in my code I just read the entire header into an array for later usage.
Here is my Constructor for my Image Class:
// Constructor
Image::Image(const char* inFileName){
// First we will initialize our Image Data Arrays:
ImageData = new int* [SIZE];
complexImageData = new complex<double>* [SIZE];
for(int i=0; i<SIZE; ++i){
ImageData[i] = new int [SIZE];
complexImageData[i] = new complex<double> [SIZE];
}
// Now we will initialize our I/O Files.
outFile = new ofstream;
inFile = new ifstream;
// And now we will fill our data arrays with the input file data.
inFile->open(inFileName,ios::in | ios::binary); // Reads file as binary
inFile->seekg(0,ios::beg); // sets filter position to beginning
inFile->read(header,HEADERSIZE); // Reads header
// Now to read in the image data:
for(int i=0; i<SIZE; ++i){
inFile->read(reinterpret_cast<char*>(ImageData[i]),SIZE);
for(int j=0; j<SIZE; ++j){
cout << ImageData[i][j] << ' ';
}
cout << endl;
}
inFile->close();
}
As you can see, it prints out the data as it is read in. The output of this constructor is strange to me. Here's the first 512 entries read into the ImageData array:

As you can see, approximately the second half of this data is all zeros. Another line is even stranger:

You can see that it also has the same zeros, but amongst those zeros are some unexpected non-zero entries. This is certainly not expected from the input image.
Any help would be greatly appreciated! I'm sorry if this is a duplicate but I tried so very hard to find an answer to my problem before posting this!
EDIT:
I noticed immediately that the numbers being printed (236854814, 237117986 etc) were not in the 8-bit range. I find this so confusing since I'm reading the data reinterpreted as a char, which is 8-bit on my system. Would it not be the case that the data being read into the integer array should be 8-bit? I even tried making my ImageData array of type __int8**, so that it could only store 8 bits per entry, but It still didn't work.
Your image is 8bpp grayscale but you read it into block int [SIZE] (supplying wrong buffer size in the process) potentially storing 4 pixel values in each int. If image is 8bpp you could've just used uint8_t buffer. You should also perform header validation (because right now your may read at wrong position) and check for actual amount of bytes read. Depending on image type / size you may also need to check padding for each line.
I have some issue where I wanted to send this information via web service. My program is using MFC 6.0. There are several other functions besides this UploadStripMapping and other functions works well. Somehow, I have some issue here where this data is not captured in the server's log. But, if I send data with wrong XML format, then the server will reply with format error.
Below is the statement that I wanted to send over:

Here's how I write the send statement in my program, the data above I set as strXML:
HTTPMethod = _bstr_t( "POST" );
httpReq->open(HTTPMethod, HTTPUrl, _variant_t(VARIANT_FALSE), _variant_t(), _variant_t());
httpReq->setRequestHeader("Content-Type", "application/soap+xml");
szRequest.Format("<?xml version=\"1.0\" encoding=\"utf-8\"?> \ <soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\"> \
<soap12:Body>\
<UploadStripMapping xmlns=\"http://tempuri.org/\"> \
<strXML>\ %s \ </strXML>\
</UploadStripMapping>\
</soap12:Body>\
</soap12:Envelope>", strXML);
vRequest.vt = VT_BSTR;
vRequest.bstrVal = szRequest.AllocSysString();
httpReq->send(vRequest);
bsResponse = httpReq->responseText;
Can anyone give some advice or point out my mistake in this code? Thanks for your help in advance.
I want to determine if a CU has been intra or inter encoded with the HEVC reference software HM 16.4 encoder.
In TEncSlice.cpp, after a CTU has been compressed (m_pcCuEncoder->compressCtu( pCtu );), I should be able to tell if a CU is intra or inter encoded.
Therefore, I check the m_pePredMode array of TComDataCU* pCtu:
Char* predMode = pCtu->getPredictionMode();
for (int i = 0; i < pCtu->getTotalNumPart(); i++)
{
std::cout << (int)predMode[i] << " ";
}
std::cout << std::endl;
PredMode is defined in TypeDef.h as:
enum PredMode
{
MODE_INTER = 0, ///< inter-prediction mode
MODE_INTRA = 1, ///< intra-prediction mode
NUMBER_OF_PREDICTION_MODES = 2,
};
The output of my code first gives me the expected result. For the first intra frame, I first only get ones (MODE_INTRA). But for certain CTUs, I also get "twos", which doesn't really make sense to me, as 2 is not supposed to describe a prediction mode.
Similarly, in the inter frames (P frames), I mostly get zeros (MODE_INTER), a few ones (MODE_INTRA), which is ok. But then I also get some "twos". A part of an example output looks like this (each row corresponds to a 64x64 CTU):
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Does anyone know what these mean? I checked if this would correspond to skip mode, but there was no correlation between the skip flag and the 2s.
Well, I got the answer to this question:
If a CU has predMode 2, this means that the CU is not coded. This happens in this case because the CUs are outside the boundaries of the picture.
The sequence that was coded had a resolution of 416x240 and the CTU size was 64x64. So there are 6.5 CTUs in a row.
This explain why every 7 CTUs, I get 2s as predMode.
