The method for computing Ambient Occlusion (AO) generally involves recording the proportion of rays that hit obstacles in the surrounding area. In addition to recording the collision ratio of rays emitted from probes, we also take into account the hit ratio of rays after they rebound off objects...
The system exhibits a high (>33 dB) peak signal-to-noise ratio in the compression and decompression of the ImageNet and Kodak24 datasets. Benchmark comparison results show that the 4-bit memristor-based storage system could reduce the latency and energy consumption by over 20×/5.6× and ...
By an image-adaptive denoising filter selection, the RDLS-modified transformation may be better-suited to characteristics of the processed data. Filters might be selected by checking the actual compression ratio obtained by a compression algorithm for the image transformed using RDLSs exploiting differen...
In the context of the high communication cost in federated learning, various gradient sparsification methods have been proposed. Previous approaches used fixed thresholds28 or fixed ratios24 as communication criteria to reduce the communication traffic between workers and the central server. However, thes...
Lossy compression techniques provide high compression ratio compared with lossless compression ratio. In lossy compression, the compressed image is not usually the same as the original one, but forms a close approximation to the original image. Therefore, some form of distortion measure is required. ...

The number of matrices contained in each MCU shall not exceed 10. For example, the ratio of row and column sampling is 4:2:2, and each MCU will contain four brightness matrices, a chromaticity matrix, and a saturation matrix. When the image data is divided into a 8*8 matrix, each ...
The optimization offered by the backward reference selection module allows an improved compression ratio and faster compression speed for lossless image compression.Inventors: Alakuijala, Jyrki (Adliswil, CH) Helminen, Hannu (Zurich, CH) Seefeld, Bernhard (New York, NY, US) ...
As for applications not requiring high compression ratio, the algorithmic complexity of the JPEG-LS is high, so that the load of the encoder is increased. As the requirement for the image resolution of the user becomes higher and higher, the load in image compression is also increased. If a...
Peak signal to noise ratio (PSNR) is defined as the peak signal of the geometry over the symmetric Root Mean Square (RMS/rms) distortion (def 8.). For colors, a similar metric is defined; the color of the original cloud is compared to the most nearby color in the degraded cloud and ...
