feat: switched `by column` reducers to the new framework for unrolled operation. note: this re-uses the `by-row` reducers. i.e. there are no special `by-column` functions. the region fetch already ensures that we have the proper in-memory layout. If we treat a row of W pixels with D bands as a row of 1 pixel with W*D bands. beware: reading the single-row statistic effectively materializes the selected columns of the input image in memory to then compute the reduction. the old code only materialized a single column as it iterated over them. beware: due to the W*D this easily drives the code into the (band > 4) case of the row reducer functions. look into possible alternatives to boost the performance of that case. note: the by band/row/column statistics are now mostly switched to the new framework. The row profiles still use the baseline, if wrapped, and the column profiles actually use a batch processor based on the ideas used for connected components. check-in: 51f25027ab user: aku tags: trunk | |

note: removed old commentary check-in: 188162a68b user: aku tags: trunk | |

tweak: some of the reduce ops feat: redone the templating used by the reducer generator. note: before - two separate pieces, the C code with simple placeholders (string mappable), and Tcl code mapping a reduce op to these placeholders, applied with `string map`. note: now - single piece of C code mixed with more complex placeholders (regexp, <<<...>>>) with arguments (key/value pairs). Generic extraction plus custom translation of the command with arguments into the proper C code, guided by the reduce op. chore: updated all def-func templates, added sourcing of the new generic mini processor where needed. check-in: 7267dc3a7e user: aku tags: trunk | |

chore: file reorg of reducer support, and band reducers note: `data/reduce` -> `support/reduce` note: fragment collection split into several files, sorted into a new dir hierarchy note: func template and setup of placeholders for same moved into single specification command - easier to match setup against the C code using them note: moved commands and state into namespace (analogous to vector math support) chore: updated users (tests, benchmarks, own codegen) check-in: 7ca3fdf0b5 user: aku tags: trunk | |
| 20:15 |

feat: performance work on the by-band statistics feat: exposing the by-band reducer variants (baseline, bands unrolled, + pixels 4-unrolled) to testing and benchmarking note: testing cross-checks the implementations against each other for equality chore: updated the notes and plots for reduction performance note: benchmarking is slow because each iteration of the reducer is given a new random input. this broader sampling of the input space should make the average a better estimate of implementation performance check-in: b05421b92c user: aku tags: trunk | |
