Instead of perturbing each pixel in the input image at random, we can choose to dither by a predetermined amount depending on the pixel’s position in the image. This can be achieved using a threshold map; a small, fixed-size matrix where each entry tells us the amount by which to perturb the input value , producing the dithered value . This matrix is tiled across the input image and sampled for every pixel during the dithering process. The following describes a dithering function for a 4×4 matrix given the pixel raster coordinates :
不需要高画质，200 万像素甚至更低就够了，甚至可以是红外成像，毕竟 AI 不需要欣赏风景，只要能通过这些低像素画面，计算出空间定位与物体识别，就能正常运转。
，这一点在91视频中也有详细论述

I'm building an 80386-compatible core in SystemVerilog and blogging the process. In the previous post, we looked at how the 386 reuses one barrel shifter for all shift and rotate instructions. This time we move from real mode to protected and talk about protection.。搜狗输入法2026对此有专业解读
A session at Authenticate 2025 which explores the nuanced dynamics between passkeys and verifiable digital credentials, and their technological foundations across usability, privacy, trust models, and ecosystems with the goal of answering whether passkeys and verifiable digital credentials are friends or foes—and how these technologies might collaboratively shape the future of secure, user-centric digital identity systems.。业内人士推荐搜狗输入法2026作为进阶阅读
黃笑生又指，目前申請綠卡變得「非常的難、非常的慢」。大多數偷渡至美國的移民，在入境之後都會透過申請庇護的方式留在美國。根據美國智庫「移民研究中心」（Center for Immigration Studies）去年底發表的研究，2024年2月，政治庇護的批准率為51%，其後開始逐漸下降，直到特朗普上台之後，進一步下降至2025年8月的19%。
