| Age and growth are primordial essential data in stock assessment and management. However, contracting experts for age estimation using calcified pieces costs several million euros annually. Yet, alternative methods exist for fish ageing using the otolith shape (i.e., otolith shape descriptors or Elliptic Fourier Analysis). The goal of this study is to use a new descriptor of the otolith shape with Mojette Transform as an input of k-Nearest Neighbors (k-NN), Random Forest (RF) and Multi-Layer Perceptron (MLP) classifiers. Mojette Transform is the exact discrete Radon transform used in tomographic reconstruction, image watermarking, or video compression. Its mathematical properties allow reducing the information and having enough redundancy to characterize... |
