A Two-Stage Optimization Strategy for Fuzzy Object-Based Analysis Using Airborne LiDAR and High-Resolution Orthophotos for Urban Road Extraction

<div>SNRs used to select the optimum scale, shape, and compactness parameters for the fuzzy object-based analysis. The SNR measures how the response varies relative to the target value under different noise conditions. The negative values are due to the logarithmic transformation used in SNR formula. The negative values indicate nonfavorable parameter values for the given task.</div>
