Creating Objects for Metaverse using GANs and AutoencodersIRJET Journal
This paper proposes a method to create objects for use in the metaverse using generative adversarial networks (GANs) coupled with an autoencoder. Specifically:
1) A GAN model called DCGAN is used to generate new images of human faces from a dataset of over 5000 images.
2) The lower quality images produced by the GAN are then upscaled using an autoencoder model to improve image quality.
3) The higher quality generated images can then be used as virtual objects that are more connected to the real world in augmented and virtual reality applications of the metaverse.

Unpaired Image Translations Using GANs: A ReviewIRJET Journal
This document reviews recent research on unpaired image translation using Generative Adversarial Networks (GANs). It discusses CycleGAN, an approach for unpaired image-to-image translation using two GANs and cycle consistency. The document reviews several papers applying CycleGAN and related methods to tasks like horse to zebra translation, summer to winter, and medical imaging. It finds CycleGAN often succeeds at color and texture changes but struggles with geometric transformations. Improving complex translations, especially geometry, remains a challenge.

Deep learning technologies are at the core of the current revolution in artificial intelligence for multimedia data analysis. The convergence of large-scale annotated datasets and affordable GPU hardware has allowed the training of neural networks for data analysis tasks which were previously addressed with hand-crafted features. Architectures such as convolutional neural networks, recurrent neural networks and Q-nets for reinforcement learning have shaped a brand new scenario in signal processing. This course will cover the basic principles and applications of deep learning to computer vision problems, such as image classification, object detection or image captioning.
The goal of this report is the presentation of our biometry and security course’s project: Face recognition for Labeled Faces in the Wild dataset using Convolutional Neural Network technology with Graphlab Framework.
Generative adversarial networks (GANs) are introduced, including the basic GAN framework containing a generator and discriminator. Various types of GANs are then discussed, such as DCGANs, semi-supervised GANs, and character GANs. The document concludes with a summary of resources on GANs and applications such as image-to-image translation and conditional waveform synthesis.
This document is a project report submitted by Shubham Jain and Vikas Jain for their course CS676A. The project aims to learn relative attributes associated with face images using the PubFig dataset. Convolutional neural network features and the RankNet model were used to predict attribute rankings. RankNet achieved better performance than RankSVM and GIST features. Zero-shot learning for unseen classes was explored by building probabilistic class models, but performance was poor. Future work could improve the modeling of unseen classes.

This document summarizes research on using a Generative Adversarial Network (GAN) called Cartoon GAN to transform real-world images and videos into cartoon images and videos. The researchers trained Cartoon GAN on 3000 real-world images to learn how to generate cartoon images by using content and adversarial loss functions. They were able to successfully convert both individual images and video clips into cartoon/animated versions. For video, they used the OpenCV library to divide videos into frames, pass each frame through the trained Cartoon GAN model, and then recombine the cartoonized frames into an output cartoon video. The researchers concluded that Cartoon GAN is an effective method for automatically transforming real media into cartoons and aims to improve the quality and resolution
IRJET- Generating 3D Models Using 3D Generative Adversarial NetworkIRJET Journal
This document discusses using a 3D generative adversarial network (GAN) to generate 3D models without needing 3D modeling software. A 3D GAN uses 3D convolutional layers in both the generator and discriminator networks. The generator maps random noise to a 3D voxel space, and the discriminator tries to determine if a 3D model is real or generated. The networks are trained adversarially, with the generator trying to fool the discriminator and the discriminator trying to accurately classify models. The goal is for the generator to learn the data distribution and output realistic 3D models without supervision by sampling latent vectors and passing them through the generator network.
The document discusses using generative adversarial networks (GANs) for text-to-image generation. GANs involve two neural networks, a generator and discriminator, that compete against each other. The generator generates images from text descriptions, while the discriminator tries to distinguish real images from generated ones. The document outlines the network architecture, literature review on GAN improvements, methodology used which involves training the GAN on a dataset to generate high resolution images from low resolution inputs conditioned on text.

An Intelligent approach to Pic to Cartoon Conversion using White-box-cartooni...IRJET Journal
This document presents an intelligent approach for converting photographs to cartoons. It proposes extracting three representations from images - the surface representation containing smooth surfaces, the structure representation containing thin color blocks and flattened surfaces, and the texture representation containing high-frequency textures and contours. A generative adversarial network is trained on these extracted representations to generate cartoonized images. The approach is implemented in a web application that allows users to upload images and obtain cartoonized outputs in a few seconds. Quantitative and qualitative evaluations demonstrate the approach outperforms previous methods.

This document summarizes the implementation of neural style transfer to combine the content of one image with the artistic style of another image. The authors used a pretrained VGG-16 convolutional neural network to extract feature representations from images. They defined a loss function combining content and style losses to minimize differences between the generated image and the style/content images. The image was iteratively updated using L-BFGS optimization. Testing with sample images achieved good results in 5 epochs, transferring the style of a painting onto photos. Further improvements could optimize speed for a web app and experiment with different parameter weights and image sizes.
IRJET- 3-D Face Image Identification from Video Streaming using Map Reduc...IRJET Journal
This document summarizes a research paper that proposes using 3D face recognition techniques and Hadoop for large-scale face identification from video streams. It describes extracting faces from video frames, representing faces as 3D models with 15 distinguishing features, and using Hadoop for parallel processing to enable fast matching of input faces against a large database of faces. The Hadoop implementation includes map and reduce processes to distribute the face matching computations across multiple servers for improved performance on large datasets.
The main objective of this work is the uniting and streamlining of an automatic face detection application and recognition system for video indexing applications. Human identification means the classification of gender which can increase the identification accuracy. So, accurate gender classification algorithms may increase the accuracy of the applications and can reduce its complexity. But, in some applications, some challenges are there such as rotation, gray scale variations that may reduce the accuracy of the application. The main goal of building this module is to understand the values in image, pattern, and array processing with OpenCV for effective processing faces for building pipe-lining, SVM models.

Generative Adversarial Networks have proven how powerful the deep neural networks and
they have created a new milestone in the field of machine learning. This project use the
work of Ian Good fellow. The main idea behind developing this project is to learn about
GAN model and LSGAN model. GAN’s or Generative models which are trained with
the samples to generate the new data using the data. In this project developed a
generative adversarial network model and Least Squares model and trained it’s sub
models one for generating fake images and another model for image classification. The
GAN and LSGAN model was developed using python keras ,torch, torchvision.

6. SUMMARY OF SURVEY PAPERS:
1. A survey of face manipulation and fake detection:
Different ways of manipulation are there like entire face synthesis, Attribute
manipulation , identity swap, expression swap.
2. A style based architecture of GAN:
Compared with traditional GAN the StyleGAN can produce more realistic image by
adding the styles. The new architecture leads to an automatically learned, unsupervised
separation of high-level attributes (e.g., pose and identity when trained on human faces)
and stochastic variation in the generated images (e.g., freckles, hair), and it enables
intuitive, scale-specific control of the synthesis.

7. SUMMARY OF SURVEY PAPERS:
3.Least Squares Generative Adversarial Networks:
Least Squares generative adversarial network (LSGANs) adopts the least squares loss
function for the discriminator. This will minimizing the Pearson divergence. First,
LSGANs are able to generate higher quality images than regular GANs. Second, LSGANs
perform more stable during the learning process.
4. Gradient Descent GAN optimization is locally stable:
Traditional GAN implemented using gradient descent optimizer. Further showed that the
recently proposed WGAN is not stable under the some conditions, but we introduced a
gradient-based regularizer which stabilizes both traditional GANs and the WGANs, and
can improve convergence speed in practice.

GAN and Least Squares GAN. This can happen just by changing the Loss function from
Binary Cross Entropy to Mean Square Error. This Project also shows the difference
between GAN and LSGAN which will solve the problems of GAN like mode collapse,
Image Quality , vanishing Gradient problems and stability during learning process.

Keras is used in this project because it is powerful open source library, Which used for
developing and evaluating deep learning models. Written in python programming
language . It is capable of running above the tensor-flow and other numerical computation
libraries. Keras allows to train and develop neural network models with fewer lines of
code.
2.PYTORCH:
PYTORCH is a defined as an open source machine learning library for python .It is used
for application such as natural language processing .It is initially developed by face book
artificial intelligence research group. Pytorch redesigns and implements torch in python
while sharing the same course c libraries for the backend code.

20. CONCLUSION AND FUTURE SCOPE
Conclusion:
This project had successfully demonstrated Generative Adversarial Networks and
LeastSquares GAN. This project had also demonstrated to test the trained GAN
model which classifies whether the image is real or fake. The whole system with all
the tools was less than 50 MB. This model can be used for other image dataset
training andclassification.
This project also demonstrated Least Squares GAN which also gives more realistic
image than the traditional GAN by using Least Squares error loss function.
Future Work:
Since the scope of this project is limited to one trained model that which is trained
with the single dataset. This can be improvised by adding more number of hidden
layers. That can also improved using different loss function and optimizer. In future
one can make application to identify whether the image is real or fake. One can also
design an application to identify the accuracy whether the written digits really
matching with generated or not.
