# histo SOPs

- [Histo preprocessing libvips container performance](/knowledge/wiki/workstreams/histo/sops/histo-preprocessing-performance)
  — why `VIPS_CONCURRENCY` must be pinned in containers, the cpu/memory
  operating point for `histo-preprocessing`, and two still-open `virdx-ome`
  bugs (full-array materialization; JPEG-only compression corrupting masks).
- [Viseg segmentation inference](/knowledge/wiki/workstreams/histo/sops/viseg-inference) — the current
  `viseg.inference` API, anatomy label map, `binarize_mask`, and resolving
  weights via ClearML.

[Dashboard histo tile serving](/knowledge/wiki/workstreams/infrastructure/sops/dashboard-histo-tile-serving).
