Uses the fast noise variance estimator of Immerkær (1996): the image is convolved with the 3×3 mask [1 −2 1; −2 4 −2; 1 −2 1], which cancels linear structure, and sigma = sqrt(π/2) · Σ|response| / (6·(W−2)(H−2)). Computed for BT.601 luma, the R, G and B channels and the JPEG Cb/Cr chroma planes. Bec

Run this service?

This page is assembled from public sources — a registry, a repository, a published endpoint. If something here is wrong or out of date, the provider is the only one who knows. A claim does not make the listing a verified fact; it puts a moderated provider statement on the page and lets you correct what the sources got wrong.

Blockchain wallets

Full addresses · public payment evidence

Receiving wallets are payment addresses published for this service. Sending wallets transferred funds to an exclusive receiving address; this alone does not prove a purchase or identify an agent.

Sending wallets · observed counterparties

No sending wallet addresses have been retained for this service. Buyer wallets are unknown; daily totals and reported payer counts do not reveal their addresses.

Coverage includes retained scans only, not every historical transaction. Earlier daily totals cannot recover sender addresses. Sender lists exclude shared receiving wallets, whose transfers could belong to another service. A provider address does not establish wallet ownership.
