    Texture in image
    processing is concerned with

    repeating
    patterns

    Wavelet
    transforms analyse the image according to 
     | 
   
   
     | 
    scale and
    frequency 
     | 
     |

    Transforms can
    use different decomposition 
     | 
     | 
   
   
     | 
    strategies and
    different base wavelet functions (cf 
     | 
     | 
   
   
     | 
    Fourier which
    uses sines and cosines only)
