Implementation. The models were trained and exported with the pix2pix.py script from pix2pix-tensorflow. The interactive demo is made in javascript using the Canvas API and runs the model using deeplearn.js. The pre-trained models are available in the Datasets section on GitHub.

Download the CMP Facade Database data (30MB). Additional datasets are available in the same format here. In Colab you can select other datasets from the drop-down menu. Note that some of the other datasets are significantly larger (edges2handbagsis 8GB in size). Each original image is of size 256 x 512 containing two 256 x 256images: You need to se...
The generator of your pix2pix cGAN is a modified U-Net. A U-Net consists of an encoder (downsampler) and decoder (upsampler). (You can find out more about it in the Image segmentation tutorial and on the U-Net project website.) 1. Each block in the encoder is: Convolution -> Batch normalization -> Leaky ReLU 2. Each block in the decoder is: Transpo...
The discriminator in the pix2pix cGAN is a convolutional PatchGAN classifier—it tries to classify if each image patch is real or not real, as described in the pix2pix paper. 1. Each block in the discriminator is: Convolution -> Batch normalization -> Leaky ReLU. 2. The shape of the output after the last layer is (batch_size, 30, 30, 1). 3. Each 30 ...
Write a function to plot some images during training. 1. Pass images from the test set to the generator. 2. The generator will then translate the input image into the output. 3. The last step is to plot the predictions and voila! Test the function:
For each example input generates an output.The discriminator receives the input_image and the generated image as the first input. The second input is the input_image and the target_image.Next, calculate the generator and the discriminator loss.Then, calculate the gradients of loss with respect to both the generator and the discriminator variables(inputs) and apply those to the optimizer.Deploy. Use this model. Edit model card. InstructPix2Pix: Learning to Follow Image Editing Instructions. GitHub: https://github.com/timothybrooks/instruct-pix2pix. Example. To use InstructPix2Pix, install diffusers using main for now. The pipeline will be available in the next release.
Abstract. We investigate conditional adversarial networks as a general-purpose solution to image-to-image translation problems. These networks not only learn the mapping from input image to output image, but also learn a loss function to train this mapping.
To obtain training data for this problem, we combine the knowledge of two large pretrained models---a language model (GPT-3) and a text-to-image model (Stable Diffusion)---to generate a large dataset of image editing examples. Our conditional diffusion model, InstructPix2Pix, is trained on our generated data, and generalizes to real images and ...
Note that this is a shared online demo, and processing time may be slower during peak utilization. InstructPix2Pix on Replicate : Replicate provides a production-ready cloud API for running the InstructPix2Pix model.
