WhatsApp Introduces HD Photos for High-Quality Media Sharing

WhatsApp has introduced an update that allows iPhone and Android users to send high-resolution photos on the messaging platform, addressing the previous limitation of low-quality image sharing. The update includes an "HD" button that users can tap to switch from the default standard quality to HD quality, with a resolution of 3024 x 4032. Recipients will see a label indicating that they have received a higher quality version, and all high-resolution images are protected by WhatsApp's end-to-end encryption. The feature is rolling out globally over the next few weeks, with high-resolution video sharing set to follow soon.

"New AI Techniques for Image Compression and Visual Question Answering"

Google researchers proposed a method that combines a standard autoencoder with a diffusion process to efficiently compress high-quality images using score-based generative models. The proposed method outperforms several recent generative approaches in terms of image quality and preserves details much better compared to state-of-the-art approaches. The study revealed specific details that can be useful for future research in this domain, such as the impact of noise schedule and the amount of noise injected during image generation.
