June 2025 performance: Delivered a cross-repo, asset-backed demonstration suite for multi-page to 2D/1D dimension reduction across four repositories (ExampleImages, FLImagingExamplesCpp, ExamplesSNAP, FLImagingExamplesCSharp). Implemented substantial asset and example growth: added 11 new Reduce Dimension assets in ExampleImages (covering Min/Max/Mean/Median/Var/Stdev/GeoMean/HarMean/Count/Mode) with a DST asset and a channel removal asset revision; expanded dimension-reduction demonstrations in FLImagingExamplesCpp, ExamplesSNAP, and FLImagingExamplesCSharp to include min/max/mean/median/variance/stddev/geometric mean/non-zero count/mode/harmean across multi-page to 2D workflows; introduced a Discrete Sine Transform (DST) example in FLImaging/SNAP streams; updated documentation and refined naming for consistency. Also performed error-handling cleanup in FLImagingExamplesCpp to improve log readability without changing behavior. The combined efforts broaden testing coverage, accelerate customer validation, and strengthen cross-language demonstration capabilities for QA, partners, and product readiness.
