sfr_calculation's Issues

vector subscript out of range error

If you run the program and have vector subscript out of range error in std::vector<double> OverSampling(cv::Mat &Src, double slope, double CCoffset, int height, int width, int *SamplingLen), you could modify the loop of average the pixel value in 4x sampling data, if the pixel value in pixel is zero, copy the value of close pixel like the following code:

	//average the pixel value in 4x sampling data, if the pixel value in pixel is zero, copy the value of close pixel
	for (i = 0; i < *SamplingLen; ++i) {
		j = 0;
		k = 1;
		if (MappingCount[i] == 0) {

			if (i == 0) {
				while (!j)
				{
					// ADD by jt 2024.1.18 prevent  vector subscript out of range error of MappingCount.
					if ((i+k) >= *SamplingLen) {
						break;
					}
					// -------------------------------------------------------------------------------
					if (MappingCount[i + k] != 0)
					{
						SamplingBar[i] = SamplingBar[i + k] / ((double)MappingCount[i + k]);
						j = 1;
					}
					else ++k;
				}
			}
			else {
				while (!j && ((i - k) >= 0))
				{
					if (MappingCount[i - k] != 0)
					{
						SamplingBar[i] = SamplingBar[i - k];   /* Don't divide by counts since it already happened in previous iteration */
						j = 1;
					}
					else ++k;
				}
				if ((i - k) < 0)
				{
					k = 1;
					while (!j)
					{
						// ADD by jt 2024.1.18 prevent  vector subscript out of range error of MappingCount.
						if ((i+k) >= *SamplingLen) {
							break;
						}
						// -------------------------------------------------------------------------------
						if (MappingCount[i + k] != 0)
						{
							SamplingBar[i] = SamplingBar[i + k] / ((double)MappingCount[i + k]);
							j = 1;
						}
						else ++k;
					}
				}
			}
		}
		else
			SamplingBar[i] = (SamplingBar[i]) / ((double)MappingCount[i]);
	}

About bug

Hello, I would like to know how to solve the problem that the program always prompts the sentence ROI size too small, please re-crop the ROI when drawing the frame. Thank you very much.
