The first reproducible result in a computer-vision project should often be a dataset audit, not a training curve. If the same physical object appears in both training and test images, a model can look impressive while answering a much easier question than the one we intended. This is especially relevant for heritage collections, where one […]

A digital twin can organize geometry, measurements and knowledge about an asset. A system that also promises to predict future conditions or compare interventions makes additional commitments. It needs a model of change, a way to update that model from evidence, and an account of uncertainty. Calling the system a world model is useful only […]

A point selected on a 3D surface is a geometric location. An annotation saying “possible repair” is an interpretation. Linking the two requires more than saving a screen coordinate, because the viewer can move, the mesh can change and the interpretation can later be revised. A useful annotation system should preserve both the selected region […]

A sensor installation can produce a very large dataset and still fail to answer a conservation question. The missing step is often the link between the damage mechanism we care about and the quantity the device actually observes. Before choosing a product, I would write down that link. Research context Our paper Sensor-Driven Preventive Preservation […]

A detailed model can show where a crack was photographed. To support a conservation decision, we also need to know when the image was taken, what else was measured, which interpretation was proposed, and who reviewed it. Those relationships do not emerge automatically from a mesh or a textured surface. A useful first step is […]

I’m pleased to share the release of my first short story, The Kingdom of Mirrors — now available as a paperback on Amazon. The book was written at a time when power did not yield to weakness – but to bluff. When a single loud figure moved, and nations built on principles watched, spoke, and […]

An assistant can produce a fluent explanation of a sensor reading without knowing whether that reading is new, whether the same situation occurred last winter, or whether a proposed intervention was actually carried out. For conservation work, those omissions are not details. They are part of the decision. A useful agent therefore needs an evidence […]

imagine
you exit to where there is no exit
just to look at what’s inside
and build more bubbles out in the nowhere
not to feel alone in the dark,
but this transforms nothing to something
by this simple given thought
and then you run back into symmetries
for a meaning all in all,
on a stage of equal weights
on which singulars are stars

It has been many years working on digitization, reconstruction and virtual world applications; tested and used various techniques covering almost all aspects in the digital recording workflow. In the recent past years our team has been successfully engaged in a very productive workflow regarding digitization and reconstruction in 3D. Specifically, this workflow involved the application […]

Interesting talk about our brains and…cooking…

Σας τα λέω όλα αυτά γιατί εδώ στο νησί μας, όπως και αλλού, οι γάτες ξεχνάνε, οι άνθρωποι ξεχνάνε και η τρέλα δε θέλει πολύ να φουντώσει πάλι φτου ξανά και απ’ την αρχή… πώς μου είχε ξεφύγει…

Free will has long been an issue on my mind. Although I am not into psychology or neuroscience I approached it in a logical/abstract way. It became apparent to me that there is no such thing as ‘free will’. The manifestations of our thoughts, our actions, which we tend to base upon free will, seem […]
