代码编译成功,但是当我尝试使用一些图像执行代码时出现以下错误。
malloc.c:3096: sYSMALLOc: 断言 `(old_top == (((mbinptr) (((char *) &((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof (size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' 失败。中止
我的代码是:
#include "opencv2/modules/imgproc/include/opencv2/imgproc/imgproc.hpp"
#include "opencv2/modules/highgui/include/opencv2/highgui/highgui.hpp"
#include <stdlib.h>
#include <stdio.h>
using namespace cv;
/// Global variables
int const min_BINARY_value = 0;
int const max_BINARY_value = 255;
Mat src, src_gray, new_image;
const char* window_name = "Web Safe Colors";
/**
* @function main
*/
int main( int argc, char** argv )
{
double sum=0, mean=0;
/// Load an image
src = imread( argv[1], 1 );
/// Convert the image to Gray
cvtColor( src, src_gray, CV_RGB2GRAY );
/// Create new image matrix
new_image = Mat::ones( src_gray.size(), src_gray.type() );
/// Calculate sum of pixels
for( int y = 0; y < src_gray.rows; y++ )
{
for( int x = 0; x < src_gray.cols; x++ )
{
sum = sum + src_gray.at<Vec3b>(y,x)[0];
}
}
/// Calculate mean of pixels
mean = sum / (src_gray.rows * src_gray.cols);
/// Perform conversion to binary
for( int y = 0; y < src_gray.rows; y++ )
{
for( int x = 0; x < src_gray.cols; x++ )
{
if(src_gray.at<Vec3b>(y,x)[0] <= mean)
new_image.at<Vec3b>(y,x)[0] = min_BINARY_value;
else
new_image.at<Vec3b>(y,x)[0] = max_BINARY_value;
}
}
/// Create a window to display results
namedWindow( window_name, CV_WINDOW_AUTOSIZE );
imshow( window_name, new_image );
/// Wait until user finishes program
while(true)
{
int c;
c = waitKey( 20 );
if( (char)c == 27 )
{ break; }
}
}
你能帮我找出问题吗?
