The Subjective Effect of Two-Dimensional Pictorial Noise

Thomas S. Huang

Research output: Contribution to journalArticlepeer-review


A study has been made of the subjective effects of the class of independent additive rectangular lowpass Gaussian noises. Three original pictures, varying in the amount of detail, were used. The general shapes of the isopreference surfaces in σ - k1 - k2 space where σ is the rms value, and k1 and k2 are the bandwidths of the noise in the horizontal and vertical directions, respectively, were found. If the objectionability of noise is a linear functional of the noise spectrum, then one may deduce that for the class of noises whose spectra are symmetrical with respect to both horizontal and vertical frequencies, the weighting function in the integral representing noise objectionability is similar in shape to these isopreference surfaces.
