Abstract
For providing a digital representation of an optical scene, radiometric values of N.times.N points representing a real two-dimensional optical scene are measured in the form of N.times.N respective electric signals x(i,j). N.times.N masks Mnm(i,j) respectively associated with the N.times.N electric signals x(i,j) are generated. For each couple (n,m), the N.times.N electric signals x(i,j) are weighted by the corresponding N.times.N masks Mnm(i,j) and the weighted electric signals are added to obtain N.times.N coefficients of the Walsh-Hadamard transform representing the optical scene.
