Group (组)

• SplitLanes4Double: Deinterleave the Double array and split it into arrays of X, Y, Z, and W (对Double数组进行解交织，拆分出 X,Y,Z,W的数组). How do I optimally fill multiple arrays with SIMDs vectors? https://stackoverflow.com/questions/77984612/how-do-i-optimally-fill-multiple-arrays-with-simds-vectors/

Image (图像)

• Bgr24ToGray8Benchmark: Converte Bgr24 color bitmap to Gray8 grayscale bitmap (将Bgr24彩色位图转为Gray8灰度位图). Why SIMD only improves performance by only a little bit for RGB to Grayscale, with SIMD multiply but scalar add of vector elements? https://stackoverflow.com/questions/77603639/why-simd-only-improves-performance-by-only-a-little-bit-for-rgb-to-grayscale-wi
• Bgr24ToGrayBgr24Benchmark: Converte Bgr24 color bitmap to grayscale Bgr24 bitmap (将Bgr24彩色位图转为灰度的Bgr24位图). C++ to C# memory alignment issue. https://stackoverflow.com/questions/79185374/c-to-c-sharp-memory-alignment-issue/
