Influence of Noise on Contour Perception

摘要：

Recognition of object is usually carried out from the contour of the object. It is important to find an, influence of noise on image recognition. Half-toning is essential processing for digital printing of continuous tone. The Sine density pattern which is the most basic picture change is treated with half- toning and adds random noise. Contour perception conditions are studied experimentally on various noise conditions, density difference, Sine waves cycle, and observation distance for the image. It is found that the contour perception is disturbed as the stimulus of the noise increases. The influences of noise are discussed form the viewpoint of HVS (Human Visual System).
