How does Greenscreen work

Computers and Technology

Drupady [299]3 years ago

<span>All of this high-tech fakery happens with the help of backdrops of brightly colored fabric or paint, and a process called "chroma key," also referred to as "green screen" due to the backdrops' color, which is typically a vivid green. ... Chroma keying isn't just for backgrounds; it works with objects, too.</span>

The minimum spanning tree of an undirected graph G exists if and only if G is connected. True or False?
zlopas [31]

Answer: True

Explanation:

The definition of minimum spanning tree(MST) says that the graph must be connected and undirected to be considered for MST. It has (V-1) edges where V is the number of vertices. The minimum spanning tree is implemented using Kruskal's algorithm whereby it starts by considering the minimum weighted edge and covers all the edges upto (V-1) edges. So for MST it has to be connected

Why is computer science hardware needed to solve problems with computers?
dybincka [34]

Answer:

Computer science is the study of problems, problem-solving, and the solutions that come out of the problem-solving process. Given a problem, a computer scientist's goal is to develop an algorithm, a step-by-step list of instructions for solving any instance of the problem that might arise. ... Algorithms are solutions.

Which one of these tasks is part of the pre-production phase of game development?
pickupchik [31]
[B], developing the art style guide and production plan.

It wouldn't be [A], because patches are released to consumers of the game, to fix bugs and add new content, which won't be done until post-production.

It wouldn't be [C] either, as it is also post-production, because you are sending the game to produced, packaged and shipped, meaning the game has already been pretty much fully developed.

Consider the two computers A and B with the clock cycle times 100 ps and 150 ps respectively for some program. The number of cyc
Kipish [7]

Answer:

Option d) B is 1.33 times faster than A

Given:

Clock time, t_{A} = 100 ps

t_{A} = 150 ps

No. of cycles per instructions,  n_{A} = 2.0

n_{B} = 1.0

Solution:

Let I be the no. of instructions for the program.

CPU clock cycle, f_{A} = 2.0 I

CPU clock cycle, f_{B} = 1.0 I

Now,

CPU time for each can be calculated as:

CPU time, T = CPU clock cycle\times clock time

T_{A} = f_{A}\times t_{A} = 2.0 I\times 100 = 200 I ps

T_{B} = f_{B}\times t_{B} = 1.0 I\times 100 = 150 I ps

Thus B is faster than A

Now,

\frac{Performance of A}{Performance of B} = \frac{T_{A}}{T_{B}}

\frac{Performance of A}{Performance of B} = \frac{200}{150}

Performance of B is 1.33 times that of A
