我正在使用Cluebat-man's LabVIEW-C++ array interoperability class,,并且从数组中提取数据时遇到错误。或者,更确切地说,数据提取似乎成功,但是当我稍后尝试使用数据时,构建失败。
(上下文:该程序旨在实现Manjunath等人的对等组过滤;该函数旨在提取图像的色相平面。我可以肯定的是,除了它的声明外,特定功能不是问题。参数,因为当我尝试使用getHuePlane()
的结果时,该问题稍后会在程序中出现)
#ifndef IO_TYPE //Normal arrays or LabVIEW?
#define I_TYPE /* int* */ CLvArrayHandlePtr<unsigned __int32, 2>
#define O_TYPE /* int* */ CLvArrayHandlePtr<unsigned __int8, 2>
#define IO_TYPE
#endif
#ifndef USING_LABVIEW_DEFINED
#define USING_LABVIEW //remove if not
#define USING_LABVIEW_DEFINED
#endif
提取和函数调用:
#include "LvArrayIndexer.h"
#include "LvArrayTemplate.h"
O_TYPE pgf(I_TYPE HSLimage, int width, int height, int halfWindowSize, int noiseThreshold) {
#ifdef USING_LABVIEW
size_t size[2] = {width, height};
HSLimage.Resize(size);
CLvArrayIndexer<unsigned __int32, 2 > baseImgIndexer(HSLimage);
CLvArrayHandlePtr<unsigned __int8, 2 > hueImage;
hueImage.Resize(size);
CLvArrayIndexer<unsigned __int8, 2 > hueImgIndexer(hueImage);
int LvImageData[width][height];
#else
int hueImage[width][height];
#endif
int hueImageData[width][height];
int windowSize = 2 * halfWindowSize - 1;
int windowLength = windowSize * windowSize;
int window[windowSize][windowSize];
int flattenedWindow[windowLength];
vector<int> peerGroup;
int currentValue;
#ifdef USING_LABVIEW
for (int x = 0; x < width; x++)
for (int y = 0; y < height; y++)
LvImageData[x][y] = baseImgIndexer[x][y];
hueImageData = getHuePlane(LvImageData, width, height);
#else
hueImageData = getHuePlane(HSLimage, width, height);
#endif
//Function continues
}
函数定义:
int* getHuePlane(int* HSLimage, int width, int height) {
int hueImage[width][height];
double calcValue;
/*Get hue plane
*AL HU SA LU ->AL HU.SA LU -> AL HUF
*AL HU -> AL.HU -> 0.HU -> HU
*/
for (int x = 0; x < width; x++) {
for (int y = 0; y < height; y++) {
calcValue = int(double(HSLimage[x][y]) / 65536); //A-H-S-L; removes S-L
calcValue = (calcValue / 256) - int(calcValue / 256);
calcValue = calcValue * 256;
hueImage[x][y] = int(calcValue);
}
}
return hueImage;
}
错误是:
pgf.cpp:88:58: error: cannot convert 'int (*)[(((unsigned int)(((int)height) + -0x000000001)) + 1)]' to 'int*' for argument '1' to 'int* getHuePlane(int*, int, int)'
系统信息:
最佳答案
我猜错误在此行上:
hueImageData = getHuePlane(LvImageData, width, height);
原因是由于类型不匹配:
LvImageData
被定义为int [][]
,而getHuePlane
需要int *
。另外,您还应该在此行上得到一个错误(在
getHuePlane
中):calcValue = int(double(HSLimage[x][y]) / 65536); //A-H-S-L; removes S-L
这是因为,当您尝试以
HSLimage
(或int *
作为参数类型)访问函数时,函数中的int [][]
是int *[]
。
