Jiangtherapee Super Resolution by 姜尧耕 y-g-jiang.github.io
JSR stacks a handheld burst of camera RAW frames into a single 2× super-resolution image — turning sub-pixel shake into real detail, while a four-layer deghost erases people, cars and swaying leaves and leaves the static scene untouched.JSR 把一组手持连拍的相机 RAW 合成为一张 2× 超分辨率图像，智能去移动物体重影。

100% crop · single template frame, AHD demosaic vs. JSR 2× — sharper, no grille moire, and the purple/green edge fringing is gone.100% 裁切 · 单张模板帧 AHD 解拜尔 对比 JSR 2×——更锐利、栅格无摩尔纹，且紫/绿边色差已消除。
How to shoot.怎么拍。
Shoot a burst of about 25 frames. Brace against a railing and shoot handheld — but don't clamp it to a rig, or you lose all displacement; a classic trick is to rest your hand on the railing (or a tripod head) to cradle the lens and steady the shot. If your camera bursts at 30 fps or more, standing and hand-holding with the electronic shutter has a high success rate too. On the computer, unzip, import and merge — about ten minutes to a finished super-resolution DNG.连拍25张左右。建议靠在栏杆上手持，但不要上架子否则一点位移都没了；一个经典的拍法就是把手放在栏杆/脚架上托着镜头拍摄，这样来稳定手持。如果你的连拍速度达到30fps+，电子快门直接站立握持连拍也有很大成功率。在电脑上解压、导入、合成，大概十分钟输出超分辨率成功的dng。
With deghosting enabled, it runs slower.去鬼影开启后速度降低。
Exceptional anti-aliasing sub-pixel alignment.尤其出色的抗混叠亚像素对齐能力。
Against every popular implementation, JSR holds the best false-colour control on a 16-frame star aliasing test.相较一切流行实现，JSR 在 16 帧星图混叠测试中拥有最好的伪色控制。
16-frame synthetic burst, each frame a random homography (rotation ≤0.8° + shift ≤3px) of the achromatic spokes.16 帧合成连拍，每帧是消色辐条的随机 homography（旋转 ≤0.8° + 平移 ≤3px）。
Mean false-colour chroma vs. radius (output px). Lower is better.平均假色 chroma vs 半径（输出像素）。越低越好。
RAW in, RAW out.RAW 进，RAW 出。
A linear DNG up to 16-bit (depending on the camera): aggressive highlight recovery, and lossless deep-shadow performance.最高16位（具体取决于相机）线性DNG：激进的高光恢复算法以及无损的极暗部表现。
Movers removed, the scene intact.运动移除，场景不动。
*When deghosting is on, a deghosting-off backup is exported too.*去鬼影开启时，也输出去鬼影关闭的备份
Purple and green fringes, aligned away.紫边、绿边，对齐消除。
JSR estimates and corrects lateral chromatic aberration on the fly — the coloured fringes even a good demosaic leaves along high-contrast edges are aligned out before the merge, so the result is clean to the pixel.JSR 在合成前自动估计并校正横向色差——即便高质量解拜尔也会在高对比边缘留下的彩边，被对齐消除，让结果干净到像素级。
Pull twice the detail out of frames you already shoot.从你本就在拍的画面里，榨出两倍细节。
