Screen content images typically contain a mix of natural and synthetic image parts. Synthetic sections usually are comprised of uniformly colored areas and repeating colors and patterns. In the VVC standard, these properties are exploited using Intra Block Copy and Palette Mode. In this paper, we show that pixel-wise lossless coding can outperform lossy VVC coding in such areas. We propose an enhanced VVC coding approach for screen content images using the principle of soft context formation. First, the image is separated into two layers in a block-wise manner using a learning-based method with four block features. Synthetic image parts are coded losslessly using soft context formation, the rest with VVC. We modify the available soft context formation coder to incorporate information gained by the decoded VVC layer for improved coding efficiency. Using this approach, we achieve Bjontegaard-Delta-rate gains of 4.98% on the evaluated data sets compared to VVC.

Soft context formation is a lossless image coding method for screen content. It encodes images pixel by pixel via arithmetic coding by collecting statistics for probability distribution estimation. Its main pipeline includes three stages, namely a context model based stage, a color palette stage and a residual coding stage. Each stage is only employed if the previous stage is impossible since necessary statistics, e.g. colors or contexts, have not been learned yet. We propose the following enhancements: First, information from previous stages is used to remove redundant palette entries and prediction errors in subsequent stages. Additionally, implicitly known stage decision signals are no longer explicitly transmitted. These enhancements lead to an average bit rate decrease of 1.16% on the evaluated data. Compared to FLIF and HEVC, the proposed method needs roughly 0.28 and 0.17 bits per pixel less on average for 24-bit screen content images, respectively.

Environmental pollution is an ever-growing concern. Industrial sites as well as agricultural use areas can bear immense harmful burdens. Unintentionally improperly disposed of wastes as well as illegally dumped chemicals pose additional risks in the environment, while remains of pharmaceuticals are a regular concern in sources of drinking water. Pollutants such as PFAS and microplastics could even be detected in the most remote regions of the earth and are known for adverse effects on humans and their environment. Establishing a comprehensive overview of where pollution of which severity and with what substances occurs is thus important, so remediations can be planned and prioritized. This necessitates fast, versatile, reliable and cheap measurements, ideally directly at sampling sites.
A promising class of transducers for detecting a multitude of pollutants are DNA Quantum Clusters. QC:DNA are highly sensitive and selective transducers for many substances, showing responses in their fluorescent behaviors based on their chemical environment. Based on the specific design, QC:DNA can interact with different chemical species and exhibit tuned excitation and emission wavelengths.
For the use of such transducers, we present a fluorescence reader integrated around capillaries. The system is designed for easy and fast customization for a large range of excitation and emission wavelengths while focusing on system portability and striving for affordability. The microfluidic system controlling and performing the assay is based on droplet sequences to facilitate fast mixing while allowing for incubation times with minimal dispersion and enabling a temporary storage and a precise processing of samples.
