Problems solved by technology

Although StackGANs can generate images based on textual descriptions, they cannot capture the localization constraints of objects in images
Image conversion is mainly through existing images, such as the pix2pix-based data generation technology proposed by Phillip Isola et al. in 2018. This technology uses the idea of ​​generative confrontation network to achieve data style conversion, but the core of the technology is The principle is to use the mapping relationship between pixels of the same scene image, so this also requires that the training data must be input in pairs, which is simply impossible for remote sensing images

specific Embodiment

[0138] The text data in the present invention is a sentence that can clearly describe a remote sensing image. The 48 pieces of data are divided into a batch, and the feature extraction and generator of the sentence are used to finally generate a low-level image of 64×64×3. resolution remote sensing images.

[0139] The features of this low-resolution remote sensing image are used as the conditional vector input of the conditional GAN, and the word features of the text data are used as the noise input, and finally a 128×128×3 medium-resolution remote sensing image is generated.

[0140] In the same way, the features of the medium-resolution remote sensing image are used as the conditional vector input of the conditional GAN, and the word features of the text data are used as the noise input, and finally a 256×256×3 high-resolution remote sensing image is generated.

[0141] After this high-resolution remote sensing image is down-sampled by the mixed_6e layer of the Inception-v3...

Abstract

The invention provides a remote sensing image style conversion method based on text data, including: constructing a data set, obtaining a text data set and an image data set to be converted; generating a low-resolution image, extracting sentence features according to the text data, and then combining noise to generate Low-resolution remote sensing images and corresponding image features; generate high-resolution images, extract word features from text data, and then combine the low-resolution features of the previous layer to generate high-resolution remote sensing images and image features of the next layer ; Calculate the loss function, detect the matching degree of the generated image and the text, and generate the corresponding loss function; image style conversion, use the generated high-resolution image as a reference style image, and perform style conversion according to the cycle consistency principle and the adversarial loss function. The beneficial effect of the invention is that high-resolution images are generated layer by layer from text data, which greatly improves the generation accuracy from text to images, and makes up for the lack of style conversion of text data.

Description

technical field [0001] The invention relates to the field of image generation, in particular to a text data-based remote sensing image style conversion method. Background technique [0002] Image generation is one of the research hotspots in the field of artificial intelligence. At present, the application of Generative Adversarial Network (GAN) extends to many fields such as video, image, text, voice, etc., especially in the field of image generation, which has achieved good results. However, there are still research gaps in style transfer from text data to images. [0003] Currently, image generation mainly includes image-to-image generation and text-to-image generation. In the original GAN, because the output only depends on random noise, it is impossible to control the content to be generated, so M. Mirza et al. proposed the CGAN algorithm in 2014. As for the text-to-image generation, the rationality and authenticity of its generation become the judging criteria of th...
