ABSTRACT
We represent a texture observed at a point (m, n) by z ( m , n ) = ∑ k = 1 p C k cos ( m λ k + n μ k ) + D k sin ( m λ k + n μ k ) , $$ z(m,n)=\sum _{k=1}^p \left\{ C_k \cos (m\lambda _k+n\mu _k) + D_k \sin (m\lambda _k+n\mu _k)\right\} , $$ https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203709733/a3b86244-1034-43cb-9a0d-166f5a5cedfd/content/um586.tif"/>
