Covers using .NET SIMD intrinsics (hardware-specific CPU instructions exposed as intrinsics since .NET Core 3) to accelerate image-processing algorithms. Describes several real image-processing algorithms, the performance bottlenecks encountered, and the optimization stages and techniques applied to achieve best throughput.
