Biomass Estimation of Mixed Forest Landscape Using a Fourier Transform Texture-Based Approach on Very-High-Resolution Optical Satellite Imagery

The paper discussed that the texture of a high resolution satellite image can yield information about the above-ground biomass(AGB) of different forest landscapes such as old-growth forests, and oil palm plantations. The AGB was assessed using Fourier Transform Textural Ordination(FOTO) method which involves both 2D Fast Fourier Transform(FFT) and ordination through Principal Component Analysis(PCA) for characterizing the structural and textural properties of vegetation.
