This sounds like a very interesting area! I guess you are the "Statistical Process Monitoring"/"Control charts"/"Shewhart charts" [0] for images. Very cool!

Is this correct or is your solution totally different? In what aspect is it most similar and most different from "Control charts"?

Are there any keywords for interested hackernews readers to research this further and play with this concept? Is it correct that you do "just" outlier detection on the embeddings of the images? I guess it works something like this:

1) Image --CNN--> Embedding: maybe enforce (properties) of distribution on the embedding (something like VAE)

2) Approximate this distribution and call a (sequence of) images an outlier if its likelihood is small. Alternatively, compare the empirical distribution of a few collected images to a distribution of "good images", e.g. via embedding into RKHS.

What type of anomalies can be detected? Does in evaluate each image separately (i.e. it cannot differentiate between objects going from left to right) or does it "understand" short sequences of images? The latter sound even more interesting. Could you provide some keywords for it.

On the production line, there are already cameras and computer vision products, e.g. Halcon. These can be used to "drag/drop" a computer vision pipeline together. Could your software be integrated into it such that the output can be further processed in Halcon etc. ?

How does this differ from instrumental? https://instrumental.com/

Instrumental focus on detecting defect in already assembled/finished products we focus on detecting anomalies in the production process itself i.e we are positioned earlier in the value chain and use video and not images like Instrumental to detect anomalies

Earlier quoted context omitted.

We are indeed focusing - my comments regarding other areas where my personal thoughts on the above question and not Cerrion's strategy.

I was going to say this seems best as a packaged solution + consulting/setup fee. I could see this working in fast-food assembly stations as well, but may have more variance with human element. Also could add on an analysis component of "study my flow and quantify potential jam points".

We are more in the mode of "deploy cerrion at your most critical production vantage points and we tell you when, why and where deviations happen". This mode doesn't require any consulting, because that every manufacturer knows their critical points and our tech doesn't need manual customization. We will focus on processes where this is always applicable and consulting is not needed to be able to achieve fast growth.

The analysis of quantifying potential jams points and surfacing targeted improvement areas is smth we are already working on given that this can be done automatically in the customers dashboard by running some correlation analysis on our detections
