Hi HN, I've been working on a bio / visual cortex inspired edge detection algorithm. I released a preliminary version a couple of months ago, and I've been improving it since. Benchmark scores currently sit midway between old-school (Canny, Sobel), and modern deep nets, while having the former's interpretability. I'm planning to develop this further for down

Review priority 41 / 100
This score orders research candidates. It is not search volume, a forecast or verified commercial demand.
Evidence
8 / 30Distinct dated articles or first observations; repeat crawling adds nothing.
Publisher diversity
8 / 25Conservative owner grouping; syndicated copies count once.
Comparable change
0 / 20Comparable complete weeks only; no percentage from a zero baseline.
Recent evidence
15 / 15Latest publication or first observation, not repeated fetch time.
Name specificity
10 / 10Explicit entities and technical concepts outrank ambiguous acronyms.
Limitations and interpretation
- First observation is a collection milestone, not proof that a word or product is new to the world.
- Counts describe monitored public sources, not the whole web or search demand.
- First observed here is not the invention date of a name or idea.
- Candidates come from public titles, summaries and entity URLs, not verified full-text analysis.
- Owner grouping is conservative; undisclosed syndication may remain.
- Sources behind this term changed or lack a comparable baseline.
- Recent evidence includes collection over three days after publication.
- The previous week is too small for a reliable percentage change.
- Current evidence comes from one publisher or owner.
