Зеленый экран служит, чтобы помочь вам установить для объекта четкий и чистый альфа канал. Это альфа может быть использована в изготовлении композиционного материала. Для того, чтобы осуществить это он смотрит на разницу в цвете между объектом и фоном. Поэтому имеет смысл, чтобы убедиться, что есть  разница, насколько это возможно. Сдвоенные несчастья являются: разлив (зеленый свет отражаясь от экрана на объект) и неравномерное освещение на экране.

Зеленый экран и освещение

Цель состоит в том что бы освещение зеленого экрана и фигуры полностью было отдельно, так что освещение одного из них не перетекало в другое.

Освещение зеленого экрана (Background Green and light)

Освещение для зеленного фона должно быть легким равномерным таким образом, чтобы сделать манипуляции проще.

  • Не беспокойтесь о краях зеленого экрана, которые не пересекались с объектом. Проблема с мусором может быть решена с помощью маски.
  • Не используйте гели или цветное освещение.
  • Не слишком темный, не слишком светлый. Либо повредит чистоту зеленого цвета (см рис1.
  • чрезмерно светло-зеленый, который повредил чистоту цвета).

Освещение фигуры (Figure–ground)

Держать FG около 2-х до 3-х метров от экрана с тем, чтобы избежать отбрасывают тени от FG на экран (который затем должен быть ключами наружу).

In November 2007 an AI pioneer at Stanford University, addressed this issue:

The problem is that we cannot yet characterize in general what kinds of computational procedures we want to call intelligent.

 John MCarthy

This informal definition signposts things that a regulator could manage, establishing and applying objective measures of ability (as defined) of an entity in one or more environments (as defined). The core focus on achievement of goals also elegantly covers other AI.

Another constraint is that AIXI lacks a “self-model” (but a recently proposed variant called “reflective AIXI” may change that).

Smart boats and yatches are already here. What does it take to acquire one?

First, the informal definition may not be directly usable for regulatory purposes because of AIXI’s own underlying constraints. One constraint, often emphasised by Hutter, is that AIXI can only be “approximated” in a computer because of time and space limitations.

Second, for testing and certification purposes, regulators have to be able to treat intelligence as something divisible into many sub-abilities (such as movement, communication, etc.). But this may cut across any definition based on general intelligence.

Intelligence measures an agent’s ability to achieve goals in a wide range of environments.

From a consumer perspective, this is ultimately all a question of drawing the line between a system defined as displaying actual AI, as opposed to being just another programmable box.

If we can jump all the hurdles, there will be no time for quiet satisfaction. Even without the Big Four, increasingly capable and ubiquitous AI systems will have a huge effect on society over the coming decades, not least for the future of employment.

The core focus on achievement of goals also elegantly covers other intelligence-related concepts such as learning, planning and problem solving.

The future of AI

First, the informal definition may not be directly usable for regulatory purposes because of AIXI’s own underlying constraints.

  • AIXI can only be “approximated” in a computer because of limitations.
  • Another constraint is that AIXI lacks a “self-model”.
  • Regulators have to be able to treat intelligence as something divisible.
  • May cut across any definition based on general intelligence.

But if the Big Four do ever (seem to) show up in AI systems, we can safely say that we’ll need not just a yacht of philosophers, but an entire regatta.
