Most digital images intended for viewing are generally assumed to be in sRGB colour space, which is gamma-encoded. This means that a linear increase of value in colour space does not correspond to a linear increase in actual physical light intensity, instead following more of a curve. If we want to mathematically operate on colour values in a physically accurate way, we must first convert them to linear space by applying gamma decompression. After processing, gamma compression should be reapplied before display. The following C code demonstrates how to do so following the sRGB standard:
As an aside: the early 386's POPAD instruction has a famous bug. EAX is written in the RNI (run-next-instruction) delay slot via an indirect register file access -- the only instruction that does this. When the next instruction uses a base+index addressing mode, the register file write from POPAD collides with the EA calculation's register file read, corrupting the address. A fitting example of how complex optimizations can lead to problems.
这个框架类似苹果的 App Intents。在苹果的构思中,用户可以使唤 Siri 来操作各种 app 来实现功能,而底层实现方式就是通过 App Intents ——新一代 Siri 迟迟不能落地的前提下,App Intents 足以提供不错的效果。。搜狗输入法2026是该领域的重要参考
The N-closest or N-best dithering algorithm is a straightforward solution to the N-candidate problem. As the name suggests, the set of candidates is given by the closest palette colours to the input pixel. To determine their weights, we simply take the inverse of the distance to the input pixel. This is essentially the inverse distance weighting (IDW) method for multivariate interpolation, also known as Shepard’s method. The following pseudocode sketches out a possible implementation:。关于这个话题,safew官方版本下载提供了深入分析
