This article examines the visual gaps between mobile IBL lighting using Split Sum Approximation and Substance Painter results, analyzes reflection direction corrections, details Prefilter map generation techniques, and proposes solutions for high‑frequency aliasing on low‑roughness surfaces.
This article explains the technical challenges of high‑latency video decoding in Android game streaming with Moonlight, analyzes why it occurs, and provides practical solutions—including API choices, immediate buffer release, frame ordering, and low‑latency vendor configurations—to achieve smoother, low‑delay gameplay.
This article reviews the CVPR2021 paper on Regressive Domain Adaptation (RegDA) for unsupervised keypoint detection, explaining its motivation, novel adversarial regression framework, sparse output-space modeling, min‑min training strategy, extensive experiments, and the resulting performance gains across multiple datasets.
This article explains the core principles of building a Nintendo Entertainment System (NES) emulator, covering the collaboration of CPU, PPU, and APU, memory mapping, ROM loading, instruction decoding, graphics rendering, and interrupt handling, with practical code examples.
This article details Kuaishou Y‑Tech's practical deployment of GAN‑based high‑precision face attribute editing—covering gender, age, hair, and expression transformations—for short‑video effects, discussing background, business applications, technical challenges, and solutions across data preparation, model training, and mobile deployment.
This article details Kuaishou Y‑tech’s Gorgeous beauty platform, covering traditional smoothing, advanced skin‑tone effects, AI‑driven blemish removal, clarity enhancement, local facial tuning, and the UNet‑based GorgeousGAN that delivers one‑click high‑definition beauty for live‑stream and short‑video applications.
This article chronicles the step‑by‑step evolution of Kuaishou's special‑effects authoring tool—from early QWidget layouts through QML redesign, then JSON/Lua configuration, and finally dynamic QML loading—highlighting how each stage reduced code size, improved developer efficiency, and enabled seamless hot updates without app releases.
This article explores the core portrait deformation techniques behind today’s beauty and body‑shaping effects—covering affine transforms, Moving Least Squares, triangulation, liquify, offset, 3D mesh, and deep‑learning approaches—detailing their principles, implementations, and visual results in live‑streaming and short‑video apps.
This article explains the fundamentals of physically based rendering (PBR) assets, the role of Substance Painter tools, image‑based lighting theory, texture export standards, and provides step‑by‑step shader code modifications to achieve consistent results between Substance Painter previews and real‑time game engines.
This article explains how KAIFX, a synthetic data platform built on computer graphics and AI techniques, tackles challenges of data scarcity, realism, labeling bias, and management to boost AR and 3D face reconstruction model performance.
