Problems solved by technology

However, the two commonly used methods of adding water ripple special effects are relatively simple, and it is difficult to render the real water ripple diffusion effect, including refraction, diffraction and attenuation caused by ripples; and the traditional water ripple special effect addition is difficult to match the attributes of the image. The fit is just a simple superposition, and it is difficult to bring a fusion special effect experience. Therefore, a method for truly expressing the special effect of water wave diffusion in images is needed.

Embodiment 1

[0046] Such as figure 1 As shown, a method for realizing the special effect of image water wave diffusion comprises the following steps:

[0047] Step 1: Get the original image, and use the original image as the texture map of the initial water surface;

[0048] Step 2: Obtain each pixel in the original image, and assign an amplitude value to each pixel as the fluctuation amplitude of the water ripple;

[0049] Step 3: Randomly or manually select m groups of n*n domain windows from the original image, and use the selected domain windows as obstacles;

[0050] Step 4: Set water ripple parameters, including initial point of water wave, wave intensity, wave width, wave speed and attenuation speed, etc.;

[0051] Step 5: Determine the ripple amplitude value of any pixel point based on the Gaussian function and the sine function;

[0052] Step 6: According to the ripple amplitude value obtained in step 5, determine the visual offset of the ripple due to refraction under lighting...

Abstract

A method and device for realizing image water wave diffusion special effect, and a storage medium, the method comprises the following steps: setting a sine wave function to simulate the shape of a water ripple, and combining a Gaussian function to further simulate a circular waveform part of a water wave in a diffusion process and a disappearing part of the water wave after the ripple contacts with an obstacle, thereby improving the real effect of water ripple rendering; when the obstacle is manually set, enabling the water ripples and the attributes of the image to be better combined so that fusion degree of the special effect is improved; By calculating and simulating the refraction effect of the water ripples, the real vision of the water ripples in the diffusion process is reduced, the dimensionality of the water ripple special effect of the image is enriched, and the real experience of a user is improved.

Description

technical field [0001] The invention relates to the field of image recognition, in particular to a method, device and storage medium for realizing special effects of image water wave diffusion. Background technique [0002] Thanks to the rapid development of handheld communication devices, image processing devices based on mobile terminals are becoming more and more popular; at the same time, users are paying more and more attention to the realistic experience of image special effects added by image processing devices. [0003] The image special effect includes a water ripple special effect, and the water ripple special effect is an effect of adding ripples to the original image. The traditional water ripple special effect processing includes two methods, one is to use the mathematical geometric model combined with wave propagation knowledge to simulate the ripple effect; the other is to superimpose the water splash video and the original image to achieve the purpose of addi...
