我们从ControlNet和腾讯的T2I-Adapter获得灵感,如下图所示,ControlNet或T2I-Adapter实质是给stable-diffusion增加一个旁路,它的训练过程是锁定stable-diffusion的参数,然后训练旁路模型。ControlNet和T2I-Adapter都已完成openpose模型的训练,即可以通过骨架图来指定角色动作。那么,我们的想法也很朴素,出于算力限制,我们要尽...

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...
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...

In actual use, an increasing value of sampling steps indicates that more details are displayed in the generated image, which is also closely related to the sampling method. For example, the sampling steps of Euler a range from 30 to 40. The image generated by using Euler a tends to be s...
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 other factors. The results will be different...

If you wish to modify the face of an already existing image instead of creating a new one, follow these steps: Open the image to be edited in the img2img tab It is recommended that you use the same settings (prompt, sampling steps and method, seed, etc.) as for the original image....
the diffusion operations in these models are carried in a semantically compressed space. Within a SD model, a U-Net performs an iterative sampling to gradually remove noise from a randomly generated latent code. This process is supported by both a text encoder and an image decoder, working coll...
