Apple with Neural 3D Engine With FaceLit, Apple proposes a neural 3D engine for face relighting. The engine should Generate 3D faces that can be rendered in various custom lighting conditions and views. The engine only needs 2D images as input. The engine relies on standard pose and lighting estimators. With these estimates, the Phong reflection model is integrated into the neural volume rendering system. The model learns how to generate the shape and material properties of a face in this way. This is also the basis for generating photorealistic facial images with multiview 3D and lighting consistency. Apple confidently...

Thanks to new OLED material, cheaper OLED TVs soon? Based on new research results from the chemistry department at Pusan National University in Korea, the development of new OLED televisions could have a major impact on the price development of future models. OLED TV manufacturing currently uses a process called thermal vacuum evaporation, which is very labor intensive and very expensive in comparison. This is also one of the main reasons why OLED TVs are still more expensive than QLED TVs. Researchers at Pusan National University succeeded in synthesizing a solvent-resistant material for the hole-injection layer used in the OLED...

Will LG OLED TVs' Filmmaker mode get an HDR upgrade? The so-called Filmmaker mode allows viewers to watch movies the way the directors intended. However, it cannot be used to play Dolby Vision High Dynamic Range content. This is set to change soon. Filmmaker Mode in LG OLED TVs is currently limited to content in SDR and HDR10. However, the UHD Alliance is currently working with TV manufacturers to introduce Filmmaker Mode for Dolby Vision as well. The news was shared by Michael Zink, president and chairman of the UHD Alliance, which developed Filmmaker mode in partnership with Hollywood, at...

New image enhancement model for smartphone real-time applications The latest camera designs have seen major advances in image processing pipelines. These enable the capture of increasingly high-quality images on smartphones. However, one thing remains: The sensor is simply too small to keep up with the large sensors of compact or DSLR cameras in terms of quality due to the form factor. The lenses are also physically too small. Therefore, the recording quality cannot match the quality of larger cameras for physical reasons alone. Nevertheless, it's amazing what image quality the latest smartphone camera models achieve. However, artifacts and other impairments...

With exception of the Arri Alexa 35, all cine cameras still only have a hardware-based (sensor) dynamic range (DR) of around 13 stops. However, using the log profiles of the camera manufacturers, it is possible to record up to 15 stops DR. However, this could change in the future, because Thomas Wocial, Konstantin D. Stefanov, William E. Martin, John R. Barnes and Hugh RA Jones have published a paper on the possibility of a new readout method for CMOS image sensors (CIS) entitled "A Method to Achieve High Dynamic Range in a CMOS Image Sensor Using Interleaved Row Readout". The...
