Research on the Effect of Image Texture Carrier on the Display Effect of Progressive Latent Image

Human visual perception has the characteristics of asymptotic priority, among which the representative illusion contour phenomenon. It is often used for psychological testing and machine vision research. Aiming at the visual phenomenon that the watermark image embedded in the image will disappear with the distance of human eyes, this paper studies its visual principle and the method to optimize its display effect. Firstly, based on the visual progressive elimination of image, the illusion contour image function is analyzed, and the sinusoidal carrier latent image function is constructed; Secondly, by controlling the independent variables horizontal frequency, vertical frequency and carrier amplitude of the image expression function, the visual display effect under the influence of various factors is explored; Finally, the evaluation function applicable to the overall image based on the misperception function is derived, and the image is evaluated objectively combined with the visual evaluation function. The experimental results show that the visual display effect of the visual eliminator image under sinusoidal carrier modulation is strongly related to the reasonable selection of the frequency and amplitude of the carrier signal, and the sinusoidal carrier wave is better than the triangular carrier for images.
