“…In this extreme scenario, the whole scattering arc needs to be reconstructed. However, rather than the computationally intensive Hough transform used in an earlier study [14], we consider that efficient edge detection algorithms, such as the active contour model (ACM) [50], should be explored.…”

“…For example, machine learning algorithms rely on rich and unbiased training samples from which they can learn to obtain accurate mappings [27]. In addition, machine learning algorithms require setting the weights of features to balance prior probabilities and fitting quality [28][29][30]. CNNs achieve high scores in automatic classification tasks, but the results of traditional CNNs for mangrove extraction rely on stable sample quality [31].…”

“…Data-scarcity is however a challenge for a lot of coastal studies as long-term datasets at large spatial scales are rare [9][10][11][12][13]. In an attempt to overcome those limitations, scientists investigating shoreline changes have turned to the use of satellite images [14][15][16][17] and many have preferred the use of open access images such as LandSat or Sentinel despite a compromise in resolution when compared with commercial image products [12,[17][18][19][20]. More recently, the development of the Google platform Earth Engine and machine learning algorithms has allowed the rapid processing of large volumes of open access satellite data back to the 70s [18][19][20].…”
