A Hands-On Guide to Evaluating AI Anomaly Detection (2/4)
When companies introduce AI visual inspection, the part most often misunderstood is "evaluation." This tutorial lets you get a feel for thresholds, the confusion matrix, and ROC/PR/F1 curves by moving sliders in a free browser app.
A Hands-On Guide to Evaluating AI Anomaly Detection (1/4)
When companies introduce AI visual inspection, the part most often misunderstood is "evaluation." What is F1, why does the threshold change the results, and how far can you trust a figure like 100%? This tutorial answers these questions hands-on.
How Are Thresholds Set in AI Visual Inspection? A Free Web App That Shows the Trade-Off of "Zero Misses" in Numbers
Choose "zero misses," and Recall (detection rate) reaches 100%. At the same time, false detections rise to 53 and Precision drops to 65%. TOMOMI RESEARCH, INC. has released a free educational demo app for exploring anomaly scores, thresholds and evaluation metrics in AI visual inspection.
Are You Really "Seeing" This Coin? Separating Color and Shape with FORESIGHT STEREO Viewer
The coins we handle every day: are we really "seeing" their surfaces? FORESIGHT STEREO Viewer is a GUI application that turns our 3D imaging technology FORESIGHT STEREO® into something people on the shop floor can operate on the spot.
RobustMAD: How Far Can We Trust the "Small AI" We Would Hand Factory Inspection To?
Ask an AI "Is there a defect in this image?" and it finds the scratch on the cable. Rephrase it as "Please confirm there is no defect" and it answers "No problem" for the same image. RobustMAD is the first systematic measure of how well small, factory-deployable inspection AIs withstand this kind of pressure.
"This Steel Sheet Has a Defect. Can You See It?" FORESIGHT STEREO Reveals a Dent Invisible in Color as "Shape"
This steel sheet has a dent, a shape defect with almost no color contrast. We captured it once with FORESIGHT STEREO and took four outputs from that single shot to show how the dent appears as shape.
What If One Capture of a Semiconductor Chip Let You See "Color" and "Shape" Separately? Observing a Semiconductor Surface with TR-100
Interference colors on a semiconductor chip hide its shape. We captured a chip once with TR-100 and used FORESIGHT STEREO to generate four outputs from that single capture, separating color from shape.
The Hardest Subject in Visual Inspection? A Mirror. Seeing Scratches and Flatness on a Reflective Surface with TR-300
A mirror shows only its reflections, never its own surface. We observed an ordinary office mirror with TR-300 and recovered the shape of the surface itself: flat at the macro level, with fine undulations and scratches invisible to the naked eye.
Bump "Discoloration" or "Crushing"? Capturing a Semiconductor Chip Once with FORESIGHT STEREO to See Color and Shape Separately
On semiconductor bump arrays, most defects live in shape, yet color and glare get in the way. We captured a copper-colored chip once with FORESIGHT STEREO and took four outputs from that single capture to separate color from shape.
Extract "Color" and "Shape" Separately from a Single Capture: Observing an Enamel Pin in 3D with FORESIGHT STEREO
Color and shape on a product surface look mixed to the human eye. We captured an enamel pin badge once with FORESIGHT STEREO and took four outputs from that single capture: peel away the color and only the shape remains.
