... Recent advances in deep learning have led to growing interest in data-driven color space alignment solutions [45]. Environmental and equipment-induced light attenuation varies non-uniformly across channels, leading to inconsistent color stylization [46]. ...

... However, properties of the human visual system are not well exploited. Although the use of YUV color space in image compression is not new, in this work, we build on our prior works [5,6] to shed some light on the effect of color spaces in learned image compression. The performance is compared with state-of-the-art image codecs by means of rate-distortion curves, Bjøntegaard delta bitrate [7], and distortion values. ...

... Encoding images with DNN models has been rapidly developed in recent years [31,34,51,52]. Despite that several works have encoded CFA images [6,10,12,27,47], there is still a long way to using neural codecs for CFA images on mobile devices with insufficient computing power. Traditional DNN methods targeting to improve humanview-experience by using more parameters in the DNN codec which induces huge time overhead and performance consumption, making ...

... Such an implementation was studied in [26], and an end-to-end latency between 70 and 350 lines, depending on the configuration, was reported. The latency also depends on the transport mechanism and whether all packets need to be transported sequentially, or if out-of-order transport is permissible. ...

JPEG XS -A new standard for visually lossless low-latency lightweight image coding

... In 2016, the Joint Photographic Experts Group (JPEG), jointly established by the International Organization for Standardization and the International Telegraph and Telephone Advisory Committee (CCITT) under the International Telecommunication Union (ITU), launched a project for low-complexity, low-latency image compression codecs [1], the JPEG XS international standard, to support fields requiring low latency and high quality, such as autonomous driving, virtual reality (VR), and broadcast television. JPEG XS is the latest international standard in the shallow compression domain, called ISO/IEC 21122: JPEG XS lowlatency lightweight image coding system [2,3], the coding standard was officially released in 2019. ...

... Entropy coding [1,2] is a type of lossless coding to compress digital data by representing frequently occurring patterns with few bits and rarely occurring patterns with many bits. A number of well-known entropy encodings include Huffman coding [3], arithmetic coding and asymmetric numeral systems (ANS) [4]. ...

Workshop 3D-ARCH "3D Virtual Reconstruction and Visualization of Complex Architectures", 21-23 February 2024, Siena, Italy Unfortunately, the human retina does not have the same unique and objective response to light as the film does. On the other hand, human visual receptors can record a brightness change greater than 10-12 log units, while camera sensors only 5-6 log units (Artusi et al. 2017). Digital cameras are incapable of fully capturing what humans sees with their eyes. ...
