在 Stable Diffusion 中，采样步数与采样器之间存在一定的关系。采样器是指用于生成随机高斯噪声的设备或算法，它直接影响着采样步骤中的噪声水平。不同的采样器可能会需要不同的采样步数来达到相同的降噪效果。因此，在选择采样步数时，我们需要综合考虑采样器的性能以及所需的降噪程度，以达到最佳的结果。通过本文的介...

stable diffusion sampling methodstable diffusion sampling method Stochastic Diffusion Sampling(SDS)方法,是一种模拟反应性分子系统的微观采样技术。它利用微观能量函数进行随机抽样,有效地采样反应性分子系统的大量配置,以描述反应性分子系统物理性质和化学反应特性。SDS以类似梯度下降的方式,从一个分子配置出发,利用量子...
后向扩散时,Stable Diffusion 先会生成一张完全的噪音图,然后根据提示词的语义,通过不断的采样来去除噪音图中不符合语义的噪音,而采样器就是去除噪音用的算法程序。 采样步数 在Stable Diffusion 中采样器和采样步数有着紧密的关系,在采样的每一步,采样器会按照一个噪音计划表控制噪音的水平,在第一步噪音水平最高...

Prompt Templates for Stable Diffusion Disclaimer Do these prompts only work with Stable Diffusion? No, they can also be used forMidjourney,DALL·E 2and other similar projects. In general the results will always depend on the chosen sampling method, dimensions of the image, chosen model and many...
Characteristic Guidance Web UI is an extension of for the Stable Diffusion web UI (AUTOMATIC1111). It offers a theory-backed guidance sampling method with improved sample and control quality at high CFG scale (10-30). This is the official implementation ofCharacteristic Guidance: Non-linear Correc...
At inference time, we generate each frame inde- pendently through a standard diffusion sampling procedure: starting with uniformly distributed Gaussian noise, the dif- fusion model is repeatedly queried with both conditioning signals to gradually denoise the noisy latent to a plausib...
hardware, photos, and the pre-trained stable diffusion model . the original implementation requires a large amount of gpu resources to train, making it difficult for common machine learning practitioners to reproduce. however, a community in discord has developed an unofficial implementation that ...
