Hello guys,
I am doing a project where I get the pixel value from a binary image (black and white - 0 and 255). Now I need to get this pixel value and send it with serial port, where a xBee is connected, but I don't know how can I do that.
I would appreciate it if someone could help me to send the pixel value to the xBee with serial port.
My code to get the pixel value from a binary image is:
#include <opencv\cv.h>
#include <opencv\highgui.h>
#include <stdio.h>
#include <stdlib.h>
int main()
{
uchar binario, valor;
FILE *fp;
fp = fopen("Pixel.txt", "w");
if(fp == NULL){
printf("\nNão encontrei arquivo\n");
exit(EXIT_FAILURE);
}
cvNamedWindow( "original", CV_WINDOW_AUTOSIZE );
cvNamedWindow( "new", CV_WINDOW_AUTOSIZE );
IplImage* src = cvLoadImage("Koala.jpg", CV_LOAD_IMAGE_GRAYSCALE);
cvShowImage("original", src);
CvSize size = cvSize(100, 100);
IplImage* resize = cvCreateImage(size, src->depth, src->nChannels);
cvResize(src, resize, CV_INTER_LINEAR);
IplImage* img_binario = cvCreateImage(cvGetSize(resize), IPL_DEPTH_8U, 1);
cvThreshold(resize, img_binario, 100, 255, CV_THRESH_BINARY);
for(int i = 0; i < img_binario->height; i++){
for(int j = 0; j < img_binario->width; j++){
binario = ((uchar *)(img_binario->imageData + i*img_binario->widthStep))[j];
if(binario == 255)
valor = 1;
else
valor = 0;
fprintf(fp, "Valor = %i\n", valor);
}
}
fclose(fp);
cvShowImage("new", img_binario);
cvWaitKey(0);
return 0;
}
Thank you.
