  2. As mentioned earlier, the CycleGAN works without paired examples of transformation from source to target domain. Recent methods such as Pix2Pix depend on the availaibilty of training examples where the same data is available in both domains. The power of CycleGAN lies in being able to learn such transformations without one-to-one mapping between training data in source and target domains

Let us tackle a simple problem that CycleGAN can address. In Chapter 3, Autoencoders, we used an autoencoder to colorize grayscale images rgb2gray(RGB) as discussed in Chapter 3, Autoencoders. Following on from that, we can use the grayscale train images as source domain images and the original color images as the target domain images

Keras implementation of CycleGAN. As discussed earlier in this chapter in the An Introduction to CycleGANs section, CycleGANs have two network architectures, a generator and a discriminator network. In this section, we will write the implementation for all the networks The CycleGAN with cycle consistency can generate more realistic and reliable images. The discriminator and the generator achieve a local optimal solution in an adversarial manner, and the generator and the classifier are in a cooperative manner to distinguish the domain of input images. A novel res-guided sampling block is proposed by combining. CycleGAN results. Based on about three days of training for about 100 epochs, the Cyclegan model seems to do a very nice job of adapting GTA to the real world domain. I really like how the smaller details are not lost in this translation and the image retains its sharpness even at such a low resolution In MMA-CycleGAN, the cycle-consistency loss and adversarial loss in CycleGAN are still used, but a mutual-attention (MA) mechanism is introduced, which allows attention-driven, long-range dependency modelling between the two image domains. Moreover, to efficiently deal with the large image size, the MA is further improved to the multi-head.

In this paper, we propose a novel underwater image enhancement method. Typical deep learning models for underwater image enhancement are trained by paired synthetic dataset.

By visual inspection, we observed that the proposed PSL method can deliver a noise-suppressed and detail-preserved image, while the TV-based method would lead to the blocky artifact, the N2V method would produce over-smoothed structures and CT value biased effect, and the CycleGAN method would generate slightly noisy results with inaccurate CT. The style classifier scored CycleGAN highest, while the content classifier gave DualGAN the edge. Ganilla ranked highest when style and content scores were averaged.

extracted 82 frames, and divided the data into train/val/test splits of 80/10/10. We then used an online photo editing tool called Birme to standardize image dimensions. For the CycleGAN method, for our training set, we have collected 53 frames from the 2D animate CycleGAN and DiscoGAN are pretty similar in terms of loss function but their neutral network structures are different. CycleGAN uses ResNet and DiscoGAN uses U-Net. In general, we found Cycl eGAN slightly outperforms DiscoGAN with the same number of epochs. DiscoGAN is more vulnerable from suffering and stuck in mode collapse.. Background: I'm currently using a variant of CycleGAN to preprocess synthetic imaging data before I use it for training another model. Shape-wise the real and synthetic datasets are very similar, but the synthetic data is a bit simpler than the real data and has some very vibrant colors not present in the real data The McAfee team used 1,500 photos of each of the project's two leads and fed the images into a CycleGAN to morph them into one another. At the same time, they used the facial recognition. For example, there are many freely available online tutorials on DCGAN and CycleGAN; much of the code in the book were also taken from open-sourced Github repo. Therefore, I went to buy a couple more books and found Image Generation with TensorFlow to be the best for my need as it covers not only the basics but also state-of-the-art models.

Most of the face generation AI you see online come from this family of model that grow the network progressively from low resolution of 4x4, 8x8, , to 1024x1024. In short, the core idea behind generative networks is capturing the underlying distribution of the data. This distribution can not be observed directly, but has to be approximately inferred from the training data. Over the years, many techniques have emerged that aim to generate data similar to the input samples A cCycleGAN is an extension of CycleGAN, which enables food category transfer among 10 types of foods and retain the shape of a given food. We experimentally show that 200 and 30,000 food images with the cCycleGAN enable a very natural food category transfer among 10 types of typical Japanese foods: ramen noodle, curry rice, fried rice, beef.
