Discrete cosine transform (DCT) [PDF]
, 2014 Kao i druge transformacije, diskretna kosinusna transformacija (DCT) nastoji dekorelirati podatke slike. Nakon dekorelacije svaki transformirani koeficijent može biti kodiran neovisno bez gubitka učinkovitosti kompresije.

Novel quantized DCT for video encoder optimization
, 2006 A novel technique is proposed to reduce the computational complexity of discrete cosine transform (DCT)-based video encoders. The proposed method merges the DCT and quantization into a single procedure, which is referred to as the novel quantized DCT ...

High‐Speed Altitude Regulation With Neuromorphic Camera and Lightweight Embedded Computation
Advanced Intelligent Systems, EarlyView.Neuromorphic cameras deliver rapid, high‐dynamic‐range sensing but overwhelm embedded processors at high speeds. This work presents a lightweight, optimized Lucas–Kanade optical flow method with parallelization, gyroscopic derotation, and adaptive event slicing.

Soft Active Electromyography Interface for Machine Learning‐Enabled Silent Speech Recognition
Advanced Intelligent Systems, EarlyView.A soft, hand‐worn electromyography interface enables intent‐driven silent speech recognition without continuous facial attachment. The device integrates liquid‐metal interconnects, a transparent flexible circuit, and elastomer encapsulation with a fingertip electrode that contacts perioral muscles only on demand.

Animal Models and Experimental Medicine, EarlyView.DPSCs, hepatocytes, and exosomes were tested for liver fibrosis therapy. Exosome‐based treatment exhibited superior antioxidative and regenerative effects. Liver enzymes, oxidative stress, and profibrotic markers were significantly reduced. α‐SMA, desmin, and related gene expression were downregulated.
