Artifact Identification
Updated 2026-08-10
INTRODUCTION
English translation pending.
CORE DEFINITION
A practice of distinguishing real signal from spurious structure that instruments, methods, or processing pipelines generate. Its proposition is that data is always the product of acquisition plus processing, so sensor noise, interpolation, normalization, and motion effects leave traces that can be mistaken for findings. Identification therefore requires tracing results back to their generative process rather than reading the final image. Qualifier: an artifact is defined by its origin, not by its visual prominence.
SCAFFOLDING EFFECT
Reduce cognitive load
- Signal authentication: Establish whether an unusual pattern comes from the phenomenon or from the method. - Control testing: Use blanks, repeats, and alternative instruments to test whether a result survives. - Pipeline tracing: Inspect processing parameters to find where spurious structure could have been introduced.
Anchor fast decisions
Every acquisition step imposes its own structure on the data, and processing steps such as interpolation or normalization impose more. When that imposed structure resembles a real pattern, the two compete for the same attention, and the more visually striking one usually wins. Tracing each candidate signal back through the pipeline reveals whether it originates in the phenomenon or in the machinery.
