How to Accelerate an Image Upscaling CNN on FPGA Using HLS

This repository contains a jupyter notebook with the implementation of a simple CNN with the objective of demonstrating how these neural networks can be used for image upscaling

Contains a module for functions that build and evaluate a U-Net Model which is a modified auto-encoder image-to-image architecture that includes skip connections from encoder to decoder layers with matching input dimensions to retain features from the encoded image. The model is designed for image segmentation and produces a mask based off x-ray data. The model is used with lung x-rays to segment out lungs, brain scans to segment out brain tumors, and pictures of a room to segment out a human figure. With the lungs dataset, it is able to manage 98% accuracy with a wide range of 3,4,5 encoding block of Conv2D and MaxPooling and BatchNormalization + 1 latent layer without pooling and the mirrored number of decoding layers that do Conv2DTranspose for deconvolution and UpScaling to reverse MaxPooling making 7,9,11 layers with doubling filters/kernels in each encoding block from 16,32,64,80 that double with each block like in a traditional CNN and then half with each decoding block.

Super-resolution using GANs. CNN, Image Classification and Image Upscaling.

Efficient sub-pixel convolutional neural networks can be used for both images and videos. ESPCN (Efficient Subpixel CNN), is a model that reconstructs a high-resolution version of an image given a low-resolution version. The ‘array’ of image upscaling filters are learned by efficient sub-pixel convolution layers.

Built a web-based platform for real-time image enhancement, exploring AI’s potential in medical imaging, security, and digital media.

An AI-powered Image Enhancement tool that improves image quality using deep learning-based super-resolution and noise reduction techniques. This project leverages CNNs and GANs to restore details, sharpen edges, and upscale low-resolution images.

This project focuses on improving the resolution of low-quality images using Convolutional Neural Networks (CNNs). The goal is to upscale images while preserving fine details, textures, and overall quality. Models were trained and tested using the

Image processing uses deep learning, like CNNs and GANs, to upscale low-resolution images by predicting missing details. Despite accuracy improvements, high-frequency details are often lacking. Our model uses a GAN framework (generator and discriminator) to produce high-quality, high-resolution images from low-quality inputs.

A U-Net-based CNN upscales images using SE blocks, pixel shuffle, and residual bottlenecks. Trained on Flickr2K with realistic degradations, MAE and perceptual-loss models improve detail recovery. Achieves strong PSNR/SSIM, producing sharper high-resolution outputs.
