I am happy to announce that my second Huawei publication "Generating Compositional Scenes via Text-to-image RGBA Instance Generation" has been accepted at NeurIPS 2024. The work has been led by our intern Alessandro Fontanella and our team leader Sarah Parisot. This work tackles a key challenge in the field of text-to-image diffusion models by focusing on improving controllability and fine-grained manipulation of generated images. While existing approaches often require tedious prompt engineering, or additional inputs such as bounding boxes, segmentation masks, clicks or scribbles, our novel approach leverages multi-layer based scene composition to give users better control over individual instance attributes, such as position, colour, and style, within complex scenes. Key Contributions: - Multi-Layer Generation Framework: Offering precise control over object attributes and scene composition. - RGBA Instance Generation: A transparency-aware method for generating isolated objects as RGBA images, allowing seamless scene composition. - Multi-Layer Noise Blending: A new strategy to build complex scenes by combining multiple object instances in a coherent, natural manner. - Modality Conditional Sampling: We leverage mutual conditioning between the RGB and Alpha channels in order to improve instance transparency coherence. Stay tuned for what's to come next.

Working Group Five focuses on the photonics applications of the materials and devices that IMOD is building and guiding the materials and architectures we investigate. Vinod, Minho and Jie walk us through recent advances and lead discussions on ideas for the next year

Closing out this quarter's captivating STS-Elionix Scientific Images https://bit.ly/3Xph1GF. The #ScientificImage we are showcasing today is - 'Information Waves', by Xing Ouyang. This image illustrates the so-called 'Fading Effect' in wireless communication systems which usually happens in a typical outdoor environment surrounded by dense buildings. The fading effect looks like the endless waves of the Atlantic Ocean, and the fluctuation of these waves indicates the strength of the radio frequency signals. This is due to the fading effect over time (horizontal) and frequency (vertical) dimensions. That’s why it called Information Waves. This fading effect is caused by both the small-scale scattering effect of a single RF signal path, created by surrounding buildings/objects and the multiple delayed transmission signal paths due to large-scale reflections. The construction and destruction of the combined scattered and reflected signal paths lead to the up and down pattern of the signal strength received by our cell phones. #ScientificImages #TyndallScientificImages #ResearchExcellence University College Cork

The paper from my internship at Huawei has been accepted to Neurips 2024! We propose an approach for layered text-to-image generation, designed for scenes with complex layouts and multiple objects with fine-grained attributes. We first fine-tune a diffusion model to generate individual objects as RGBA images with transparency. These objects are then composited into multi-instance scenes using a noise-blending technique, where each instance is associated with a specific image layer.

As the International Conference on Acoustics, Speech, and Signal Processing #ICASSP2024 approaches, I am excited to announce that I will be presenting my paper "Dynamic Bandwidth Variational Mode Decomposition" as a poster presentation on April 16 from 13:10 - 15:10 KST at Poster Zone 6C. If you're attending #ICASSP2024 be sure to swing by my poster session and say hello! Can't wait to engage in discussions with fellow researchers, exchange insights, and expand my network within the field. #ICASSP #signalprocessing

Invisibility has always been an intriguing and challenging optical phenomenon: https://lnkd.in/eJzndFzR University of Glasgow and Masaryk University researchers propose “shift invisibility cloaks,” transformation optical devices that appear to shift an interior region of space to the outside. Built from homogenous blocks of materials, the shifty cloaks can be applied to make other transformation optical devices, such as perfect invisibility cloaks, Janus devices, or optical wormholes.
