Column-first iteration for Error Diffusion

[adrhill]

Transposes the ED filter matrices in the Error Diffusion constructor to iterate over CartesianIndices(img) instead of rows of the image.

I'm temporarily transposing reference tests until they are passed in this PR, then I will update the references.

[adrhill]

Not sure why reference tests pass on binary images but fail on color images.

An empty cell means that the value was zero. | ID | time | GC time | memory | allocations | |--------------------------------------------------|----------------:|----------:|----------------:|------------:| | `["closest color", "binary inplace"]` | 7.500 μs (5%) | | 64.11 KiB (1%) | 2 | | `["closest color", "binary new"]` | 4.683 μs (5%) | | 64.11 KiB (1%) | 2 | | `["closest color", "color inplace"]` | 196.114 ms (5%) | | 36.48 MiB (1%) | 2357848 | | `["closest color", "color new"]` | 202.937 ms (5%) | 3.391 ms | 36.48 MiB (1%) | 2357848 | | `["closest color", "per-channel inplace"]` | 1.027 ms (5%) | | 192.05 KiB (1%) | 2 | | `["closest color", "per-channel new"]` | 998.604 μs (5%) | | 192.05 KiB (1%) | 2 | | `["error diffusion", "binary inplace"]` | 1.177 ms (5%) | | 320.23 KiB (1%) | 5 | | `["error diffusion", "binary new"]` | 1.230 ms (5%) | | 320.23 KiB (1%) | 5 | | `["error diffusion", "color inplace"]` | 169.332 ms (5%) | | 16.44 MiB (1%) | 995660 | | `["error diffusion", "color new"]` | 156.637 ms (5%) | | 16.44 MiB (1%) | 995660 | | `["error diffusion", "per-channel inplace"]` | 4.190 ms (5%) | | 960.42 KiB (1%) | 11 | | `["error diffusion", "per-channel new"]` | 4.312 ms (5%) | | 960.42 KiB (1%) | 11 | | `["ordered dithering", "binary inplace"]` | 107.800 μs (5%) | | 69.42 KiB (1%) | 5 | | `["ordered dithering", "binary new"]` | 104.500 μs (5%) | | 69.42 KiB (1%) | 5 | | `["ordered dithering", "color inplace"]` | 932.330 ms (5%) | 28.242 ms | 364.51 MiB (1%) | 14417965 | | `["ordered dithering", "color new"]` | 1.132 s (5%) | 39.572 ms | 401.20 MiB (1%) | 16473466 | | `["ordered dithering", "per-channel inplace"]` | 1.163 ms (5%) | | 207.98 KiB (1%) | 11 | | `["ordered dithering", "per-channel new"]` | 1.147 ms (5%) | | 207.98 KiB (1%) | 11 | | `["threshold dithering", "binary inplace"]` | 13.000 μs (5%) | | 128.22 KiB (1%) | 4 | | `["threshold dithering", "binary new"]` | 11.300 μs (5%) | | 128.22 KiB (1%) | 4 | | `["threshold dithering", "per-channel inplace"]` | 969.405 μs (5%) | | 384.38 KiB (1%) | 8 | | `["threshold dithering", "per-channel new"]` | 998.005 μs (5%) | | 384.38 KiB (1%) | 8 | ## Benchmark Group List Here's a list of all the benchmark groups executed by this job: - `["closest color"]` - `["error diffusion"]` - `["ordered dithering"]` - `["threshold dithering"]` ## Julia versioninfo ``` Julia Version 1.7.3 Commit 742b9abb4d (2022-05-06 12:58 UTC) Platform Info: OS: Linux (x86_64-pc-linux-gnu) Ubuntu 20.04.4 LTS uname: Linux 5.13.0-1031-azure #37~20.04.1-Ubuntu SMP Mon Jun 13 22:51:01 UTC 2022 x86_64 x86_64 CPU: Intel(R) Xeon(R) CPU E5-2673 v4 @ 2.30GHz: speed user nice sys idle irq #1 2294 MHz 2335 s 2 s 189 s 3829 s 0 s #2 2294 MHz 4599 s 1 s 282 s 1481 s 0 s Memory: 6.783603668212891 GB (3575.46484375 MB free) Uptime: 641.82 sec Load Avg: 1.0 1.08 0.71 WORD_SIZE: 64 LIBM: libopenlibm LLVM: libLLVM-12.0.1 (ORCJIT, broadwell) ``` --- # Runtime information | Runtime Info | | |:--|:--| | BLAS #threads | 2 | | `BLAS.vendor()` | `openblas64` | | `Sys.CPU_THREADS` | 2 | `lscpu` output: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian Address sizes: 46 bits physical, 48 bits virtual CPU(s): 2 On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 2 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 79 Model name: Intel(R) Xeon(R) CPU E5-2673 v4 @ 2.30GHz Stepping: 1 CPU MHz: 2294.688 BogoMIPS: 4589.37 Hypervisor vendor: Microsoft Virtualization type: full L1d cache: 64 KiB L1i cache: 64 KiB L2 cache: 512 KiB L3 cache: 50 MiB NUMA node0 CPU(s): 0,1 Vulnerability Itlb multihit: KVM: Mitigation: VMX unsupported Vulnerability L1tf: Mitigation;
