論文Fast Affine Template Matching over Galois Field熱力圖實現

論文效果：

我的效果：

後面的圖不列出來了，效果非常接近

上代碼：

EvaluateConfigs_mex.cpp加入如下代碼：

    ......

    double *targetImgPointFrequency;
    plhs[1] = mxCreateDoubleMatrix(w2, h2, mxREAL);
    targetImgPointFrequency = mxGetPr(plhs[1]);

    ......


	if (!usePhotometrics) {
		for (int j = 0; j < numPoints ; j++) {
			targetPoint_x = int(a11*(*ptrXsc) + a12*(*ptrYsc) + tmp1); 
			targetPoint_y = int(a21*(*ptrXsc) + a22*(*ptrYsc) + tmp2); 
			targetInd = (targetPoint_y - 1)*w2 + targetPoint_x - 1; // -1 is for c

			int index_c = targetInd%(h2*w2);//add code
			targetImgPointFrequency[index_c] += 1;//add code

			score += (fabs((*ptrVals) - img2[targetInd]));
			ptrVals++;
			ptrXsc++;
			ptrYsc++;
		}
	}

    ......

FindBestTransformation.m加入如下代碼：

        if (isGrayscale)
            [distances,targetImgPointFrequency] = EvaluateConfigs_mex(I1',I2',matrixConfigs_mex,int32(xs),int32(ys),int32(photometricInvariance));
            fprintf('----- Evaluate Configs grayscale, with %d configs -----\n',size(configs,1));
        else
            distances = EvaluateConfigsVectorized_mex(permute(I1,[3,2,1]),permute(I2,[3,2,1]),matrixConfigs_mex,int32(xs),int32(ys),int32(photometricInvariance));
            fprintf('----- Evaluate Configs vectorized, with %d configs -----\n',size(configs,1));
        end

        EvaluateConfigs_mex_time = toc(EvaluateConfigsMEX);
        
        totTime = totTime + Configs2Affine_mex_time + EvaluateConfigs_mex_time;
