首先我们知道,text-guided image generation问题并不是一个新问题,早在GAN的时代,各种模型就对这个问题进行了探讨,然而因为以前的模型训练数据和生成模式受限,生成的结果并不逼真。近些年来无条件图像生成模型的发展,特别是近几年大火的基于diffusion的模型,使得无条件图像生成的结果可以直逼真实图像,因此作者期望在当前无...
最后是训练时的一个小trick,作者在训练时为了缓解训练数据不足的问题,在训练上述两个目标的同时,还引入了训练Stable diffusion的数据集(LAION-Aesthetics v2 5+)训练text-guided image generation任务,这个任务可以被近似的看做一个mask覆盖整个图像的edit任务。 Expression 最后是实验部分的两眼之处。首先是不同方法ed...
Language Guided Diffusion 利用CLIP模型的文本编码器和图像编码器,在某一时刻计算逆向过程生成图像的image embedding和给定描述的language embedding,经过L2归一化之后计算余弦相似度,基于该相似度损失来计算梯度,文本引导函数定义为: 文本引导函数 但是CLIP中的图像编码器在训练时没见过噪声图像,因此需要用噪声图像finetune...
Finally, we suggest a new metric for evaluating image manipulation results, in terms of both the generation of new attributes and the reconstruction of text-irrelevant contents. Extensive experiments on the CUB and COCO datasets demonstrate the superior performance of the proposed method. Code is ...

We propose a text-guided variational image generation method to address the challenge of getting clean data for anomaly detection in industrial manufacturing. Our method utilizes text information about the target object, learned from extensive text library documents, to generate non-defective data images...
此外，GLIDE(Guided Language to Image Diffusion for Generation and Editing)模型还可以微调进行图像修复，从而实现强大的文本驱动的图像编辑。本文在过滤后的数据集上训练了一个较小的模型，地址：https://github.com/openai/glide-text2im。首先简单介绍扩散模型：扩散模型通常包括两个过程，从信号逐步到...
Conversation input text is received from a user of a portable device that includes a display. Model input text is generated from the conversation input text, which is processed with a text-to-image model to generate an image based on the model input text. The coordinates of a face in the...
