MFC-FingerPrint

基于MFC开发的指纹识别系统.

欢迎关注公众号,开启和我的交流

weix


效果图如下:

1

在第12步特征入库中,会对当前指纹的mdl数据与databases中所有的mdl进行对比,然后返回识别结果.

一.载入图像

在点击之后,选择需要识别的图片. 图片路径为beginfilename.

void CFingerDlg::OnBnClickedOk1()
{
	CFileDialog    dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.bmp)|*.bmp|All Files (*.*)|*.*||"), NULL);

	if (dlgFile.DoModal())
	{
		strFile = dlgFile.GetPathName();
	}
	char *info = "";

	USES_CONVERSION;
	char * beginfilename = T2A(strFile);
	Step1_LoadBmpImage(beginfilename,info);

	ShowImageInCtrl(m_picCtrl1, beginfilename);

	// TODO: 在此添加控件通知处理程序代码
}

Step1_LoadBmpImage中就是获取初始图片的RGB信息.

int Step1_LoadBmpImage(char *beginfilename,char* info) {
	char *filename = beginfilename;
	CopyFile(ToWideChar(filename), ToWideChar(STEP_TXT_1), false);

	int iWidth, iHeight, iDepth;
	int flag = ReadBMPImgFilePara(filename, iWidth, iHeight, iDepth);
	if (flag != 0) {
		//sprintf(info,"图像加载失败");
		::MessageBox(NULL, _T("图像加载失败"), _T("error"), MB_OK);
		return -1;
	}
	unsigned char *data = new unsigned char[iWidth*iHeight];
	flag = ReadBMPImgFileData(filename, data);
	if (flag != 0) {
		//sprintf(info, "图像数据读取失败");
		::MessageBox(NULL, _T("图像数据读取失败"), _T("error"), MB_OK);
		delete[] data;
		return -2;
	}
	flag = SaveDataToTextFile(STEP_TXT_1, data, iWidth, iHeight);
	if (flag != 0) {
		//sprintf(info,"数据保存失败");
		::MessageBox(NULL, _T("数据保存失败"), _T("error"), MB_OK);
		delete[] data;
		return -3;
	}
	//sprintf(info, "源图[%s],宽度[%d],高度[%d],深度[%d b]",filename,iWidth,iHeight,iDepth);
	delete[] data;
	return 0;
}

其中具体的Txt与BMP转换参考具体源代码.


二.中值滤波

中值滤波实现算法,ucImg由第一步得来.

int MidFilter(unsigned char *ucImg, unsigned char *ucDstImg, int iWidth, int iHeight) {
	memset(ucDstImg, 0, iWidth*iHeight);
	unsigned char *pUp, *pDown, *pImg;
	unsigned char x[9];
	for (int i = 1; i < iHeight - 1; i++) {
		pUp = ucImg + (i - 1)*iWidth;
		pImg = ucImg + i * iWidth;
		pDown = ucImg + (i + 1)*iWidth;
		int j;
		for (j = 1; j < iWidth - 1; j++) {
			pUp++;
			pImg++;
			pDown++;
			x[0] = *(pUp - 1);
			x[1] = *(pImg - 1);
			x[2] = *(pDown - 1);
			x[3] = *pUp;
			x[4] = *pImg;
			x[5] = *pDown;
			x[6] = *(pUp + 1);
			x[7] = *(pImg + 1);
			x[8] = *(pDown + 1);

			Sort(x, 9);
			*(ucDstImg + i * iWidth + j) = x[4];
		}
	}
	int j;
	pDown = ucImg + iWidth;
	for (j = 1; j < iWidth - 1; j++) {
		x[0] = *(ucImg + j - 1);
		x[1] = *(ucImg + j);
		x[2] = *(ucImg + j + 1);
		x[3] = *(pDown + j - 1);
		x[4] = *(pDown + j);
		x[5] = *(pDown + j + 1);
		Sort(x, 6);
		*(ucDstImg + j) = x[3];
	}
	pUp = ucImg + iWidth * (iHeight - 2);
	pDown = ucImg + iWidth * (iHeight - 1);
	for (j = 1; j < iWidth - 1; j++) {
		x[0] = *(pDown + j - 1);
		x[1] = *(pDown + j);
		x[2] = *(pDown + j + 1);
		x[3] = *(pUp + j - 1);
		x[4] = *(pUp + j);
		x[5] = *(pUp + j + 1);
		Sort(x, 6);
		*(ucDstImg + iWidth * (iHeight - 1) + j) = x[3];
	}
	x[0] = *(ucImg);
	x[1] = *(ucImg + 1);
	x[2] = *(ucImg + iWidth);
	x[3] = *(ucImg + iWidth + 1);
	Sort(x, 4);
	*(ucDstImg) = x[2];

	x[0] = *(ucImg + iWidth - 1);
	x[1] = *(ucImg + iWidth - 2);
	x[2] = *(ucImg + 2 * iWidth - 1);
	x[3] = *(ucImg + 2 * iWidth - 2);

	Sort(x, 4);
	*(ucDstImg + iWidth - 1) = x[2];

	x[0] = *(ucImg + iWidth * (iHeight - 1));
	x[1] = *(ucImg + iWidth * (iHeight - 2));
	x[2] = *(ucImg + iWidth * (iHeight - 1) + 1);
	x[3] = *(ucImg + iWidth * (iHeight - 2) + 1);
	Sort(x, 4);
	*(ucDstImg + (iHeight - 1)*iWidth) = x[2];
	x[0] = *(ucImg + iWidth * (iHeight - 0) - 1);
	x[1] = *(ucImg + iWidth * (iHeight - 1) - 1);
	x[2] = *(ucImg + iWidth * (iHeight - 0) - 2);
	x[3] = *(ucImg + iWidth * (iHeight - 1) - 2);
	Sort(x, 4);

	*(ucDstImg + (iHeight - 0)*iWidth - 1) = x[2];

	return 0;
}

三.均值化

int HistoNormalize(unsigned char* ucImg,unsigned char* ucNormImg, int iWidth,int iHeight) {
	unsigned int Histogram[256];

	memset(Histogram, 0, 256 * sizeof(int));
	for (int i = 0; i < iHeight; i++) {
		for (int j = 0; j < iWidth; j++) {
			Histogram[ucImg[i*iWidth + j]]++;
		}
	}
	double dMean = 0;
	for (int i = 1; i < 255; i++) {
		dMean += i * Histogram[i];
	}
	dMean = int(dMean/(iWidth*iHeight));
	double dSigma = 0;
	for (int i = 0; i < 255; i++) {
		dSigma += Histogram[i] * (i - dMean)*(i-dMean);
	}
	dSigma /= (iWidth*iHeight);
	dSigma = sqrt(dSigma);

	double dMean0 = 128, dSigma0 = 128;
	double dCoeff = dSigma0 / dSigma;
	for (int i = 0; i < iHeight; i++) {
		for(int j=0;j<iWidth;j++){
			double dVal = ucImg[i*iWidth + j];
			dVal = dMean0 + dCoeff * (dVal-dMean0);
			if (dVal < 0) {
				dVal = 0;
			}
			else if (dVal > 255) {
				dVal = 255;
			}
			ucNormImg[i*iWidth + j] = (unsigned char)dVal;
		}
	}
	return 0;
}

四.方向计算

int ImgDirection(unsigned char* ucImg,float* fDirc,int iWidth,int iHeight) {
	const int SEMISIZ = 7;
	int dx[SEMISIZ * 2 + 1][SEMISIZ * 2 + 1];
	int dy[SEMISIZ * 2 + 1][SEMISIZ * 2 + 1];
	float fx, fy;
	memset(fDirc, 0, iWidth*iHeight * sizeof(float));
	for (int y = SEMISIZ + 1; y < iHeight - SEMISIZ - 1; y++) {
		for (int x = SEMISIZ + 1; x < iWidth - SEMISIZ - 1; x++) {
			for (int j = 0; j < SEMISIZ * 2 + 1; j++) {
				for (int i = 0; i < SEMISIZ * 2 + 1; i++) {
					int index1 = (y + j - SEMISIZ)*iWidth + x + i - SEMISIZ;
					int index2 = (y + j - SEMISIZ)*iWidth + x + i - SEMISIZ - 1;
					int index3 = (y + j - SEMISIZ - 1)*iWidth + x + i - SEMISIZ;
					dx[i][j] = int(ucImg[index1] - ucImg[index2]);
					dy[i][j] = int(ucImg[index1] - ucImg[index3]);
				}
			}
			fx = 0.0;
			fy = 0.0;
			for (int j = 0; j < SEMISIZ * 2 + 1; j++) {
				for (int i = 0; i < SEMISIZ * 2 + 1; i++) {
					fx += 2 * dx[i][j] * dy[i][j];
					fy += (dx[i][j] * dx[i][j] - dy[i][j] * dy[i][j]);
				}
			}
			fDirc[y*iWidth + x] = atan2(fx,fy);
		}
	}
	return 0;
}

	const int DIR_FILTER_SIZE = 2;
	int blocksize = 2 * DIR_FILTER_SIZE + 1;
	int imgsize = iWidth * iHeight;
	float *filter = new float[blocksize*blocksize];
	float *phix = new float[imgsize];
	float *phiy = new float[imgsize];
	float *phi2x = new float[imgsize];
	float *phi2y = new float[imgsize];
	memset(fFitDirc,0,sizeof(float)*iWidth*iHeight);
	float tempSum = 0.0;
	for (int y = 0; y < blocksize; y++) {
		for (int x = 0; x < blocksize; x++) {
			filter[y*blocksize + x] = (float)(blocksize - (abs(DIR_FILTER_SIZE - x) + abs(DIR_FILTER_SIZE - y)));
			tempSum += filter[y*blocksize + x];
		}
	}
	for (int y = 0; y < blocksize; y++) {
		for (int x = 0; x < blocksize; x++) {
			filter[y*blocksize + x] /= tempSum;
		}
	}
	for(int y=0;y<iHeight;y++){
		for (int x = 0; x < iWidth; x++) {
			phix[y*iWidth + x] = cos(fDirc[y*iWidth + x]);
			phiy[y*iWidth + x] = sin(fDirc[y*iWidth + x]);
		}
	}
	memset(phi2x, 0, sizeof(float)*imgsize);
	memset(phi2y, 0, sizeof(float)*imgsize);
	float nx, ny;
	int val;
	for (int y = 0; y < iHeight - blocksize; y++) {
		for (int x = 0; x < iWidth - blocksize; x++) {
			nx = 0.0;
			ny = 0.0;
			for (int j = 0; j < blocksize; j++) {
				for (int i = 0; i < blocksize; i++) {
					val = (x + i) + (j + y)*iWidth;
					nx += filter[j*blocksize + i] * phix[val];
					ny += filter[j*blocksize + i] * phiy[val];
				}
			}
			val = x + y * iWidth;
			phi2x[val] = nx;
			phi2y[val] = ny;
		}
	}

	for (int y = 0; y < iHeight - blocksize; y++) {
		for (int x = 0; x < iWidth - blocksize; x++) {

		}
	}
	delete[] phi2y;
	delete[] phi2x;
	delete[] phiy;
	delete[] phix;

	float freqMin = 1.0 / 25.0;
	float freqMax = 1.0 / 3.0;
	int x, y, k;
	int pos, posout;
	memset(ucMask,0,iWidth*iHeight);

			}
		}
	}
	for (k = 0; k < 12; k++) {

	float dy2 = 1.0 / (4.0*4.0);
	memset(ucImgEnhanced,0,iWidth*iHeight);
	for (j = wg2; j < iHeight - wg2; j++) {
		for (i = wg2; i < iWidth - wg2; i++) {

			g = fDirection[i+j*iWidth];
			f = fFrequency[i+j*iWidth];
			g += PI / 2;
			sum = 0.0;
			for (v = -wg2; v <= wg2; v++) {
				for (u = -wg2; u <= wg2; u++) {
					x2 = -u * sin(g) + v * cos(g);
