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...

Tone mapping operators with AI High Dynamic Range (HDR) is fast becoming the video format of choice for content providers, albeit not quite as quickly as thought. Standard Dynamic Range (SDR) displays still dominate the market. Therefore, efficient ways must be found to convert HDR content to SDR format, a process known as tone mapping. There are already numerous tone mapping operators (TMO for short), but these do not always lead to a usable result. Recently, many "new" TMOs based on deep learning approaches have been proposed. However, the main challenge in training such deep learning networks is the lack...

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...

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...
