Setting Filtering and Thresholding

It is possible to activate a pre-processing stage in the LLE process. In the example shown in Figure 12 - Filtering and Thresholding parameters, the threshold level is set to 20 and the convolution filter kernel is set with A=2, B=5, and C=2. With these parameters, we will have a smoother image where any background noise below the threshold level is replaced by 0.
