将cvx_defs.h直接放在主程序上面,并删除主程序中的#include"cvx_defs.h."
cvx_defs.h如下:

#pragma once
#include <cv.h>

#define CVX_DONT_CARE -1

#define CVX_CAMERA        0
#define CVX_AVI                1

#define CVX_RED                CV_RGB(0xff,0x00,0x00)
#define CVX_GREEN        CV_RGB(0x00,0xff,0x00)
#define CVX_BLUE        CV_RGB(0x00,0x00,0xff)

#define CVX_CYAN        CV_RGB(0x00,0xff,0xff)
#define CVX_MAGENTA        CV_RGB(0xff,0x00,0xff)
#define CVX_YELLOW        CV_RGB(0xff,0xff,0x00)

#define CVX_WHITE        CV_RGB(0xff,0xff,0xff)
#define CVX_BLACK        CV_RGB(0x00,0x00,0x00)
#define CVX_GRAY50        CV_RGB(0x88,0x88,0x88)

typedef struct {
        float x;
        float y;
        float width;
        float height;
}
CvxRect32f;

CV_INLINE  CvxRect32f  cvxRect32f(
        float x,
        float y,
        float width,
        float height
        ) {
        CvxRect32f r;

        r.x = x;
        r.y = y;
        r.width = width;
        r.height = height;

        return r;
}

#define CVX_HSV( h, s, v )  cvScalar( (h), (s), (v), 0 )

CvScalar cvx_hsv2rgb(CvScalar hsv);
