In this research, we introduce RefineNet, a novel architecture designed to
address resolution limitations in text-to-image conversion systems. We explore
the challenges of generating high-resolution images from textual descriptions,
focusing on the trade-offs between detail accuracy and computational
efficiency. RefineNet leverages a hierarchical Transformer combined with
progressive and conditional refinement techniques, outperforming existing
models in producing detailed and high-quality images. Through extensive
experiments on diverse datasets, we demonstrate RefineNet's superiority in
clarity and resolution, particularly in complex image categories like animals,
plants, and human faces. Our work not only advances the field of image-to-text
conversion but also opens new avenues for high-fidelity image generation in
various applications.

RefineNet: Enhancing Text-to-Image Conversion with High-Resolution and  Detail Accuracy through Hierarchical Transformers and Progressive Refinement

In digital photography, two image restoration tasks have been studied
extensively and resolved independently: demosaicing and super-resolution. Both
these tasks are related to resolution limitations of the camera. Performing
super-resolution on a demosaiced images simply exacerbates the artifacts
introduced by demosaicing. In this paper, we show that such accumulation of
errors can be easily averted by jointly performing demosaicing and
super-resolution. To this end, we propose a deep residual network for learning
an end-to-end mapping between Bayer images and high-resolution images. By
training on high-quality samples, our deep residual demosaicing and
super-resolution network is able to recover high-quality super-resolved images
from low-resolution Bayer mosaics in a single step without producing the
artifacts common to such processing when the two operations are done
separately. We perform extensive experiments to show that our deep residual
network achieves demosaiced and super-resolved images that are superior to the
state-of-the-art both qualitatively and in terms of PSNR and SSIM metrics.
