Ringing – high contrast areas with waves
Contouring, Banding, Pposterisation – extreme brightness changes
Staircase noise – along curving edges
Blockiness in “busy” regions – may mimick duplications
Gibbs phenomenon – small highlighted area of large contrast
Alias, Moiré, frequent color/brightness change
Now let’s have a look at the compression artifacts in descending quality (BTW this also good exercise for the upcoming 125kB Content Upload Filter, I am therefore adding also filesize here)
The plot above is the result of the “World Value Survey”. It assumes that there are two major dimensions of cross cultural variation in the world: “Traditional values versus secular-rational values” and “Survival values versus self-expression values”.
Sounds interesting at least for 3 seconds. Then we are discovering the strange axis labels – the opposite of tradition is lost tradition not rational value. The authors explain traditional values by the importance of religion, parent-child ties, deference to authority and traditional family values. People who embrace these values also reject divorce, abortion, euthanasia and suicide. These societies have high levels of national pride and a nationalistic outlook.
As a protestant, Inglehart–Welzel put me top right “having less or no traditional values, no religion, parent-child ties, no need for authority and traditional family values”. According to them I am “pro divorce, abortion, euthanasia and suicide with low level of national pride” – which is clearly wrong, just by a simple example.
I am quite sure that a single item analysis – lets say divorce rate vs Gross Domestic Product would compare countries much better. But do we even need such kind of science? The whole scheme is dangerously simplified – producing more stereotypes that I would have expected from any political scientists.
Damit stoße ich nun wieder an ihre alte Frage an mich: wie ich mich denn in dieser Zeit als Deutscher fühle? Meine Antwort muß sein: Gar nicht. So wie Hölderlin einst sagte, es sei die Zeit der Könige nicht mehr, so ist nun die Zeit der Völker nicht mehr. (Heinrich Blücher)
