What is the key difference between a location vector and a displacement vector?

A location vector has direction and magnitude, while a displacement vector only has magnitude.

A location vector is represented by coordinates, while a displacement vector is represented by pixel intensities.

A location vector is relative to the origin, while a displacement vector is relative to another point. (correct)

A location vector is always of size 3, while a displacement vector can vary in size.

In the RGB model, how is each color represented?

By a vector of size 3 with pixel intensities for red, green, and blue. (correct)

By a vector of size 4 with pixel intensities for primary and secondary colors.

By a vector of size 2 with pixel intensities for primary colors.

By a single scalar value indicating color intensity.

How are color images typically represented in terms of pixel intensities?

By a single intensity value per pixel arranged sequentially in a vector.

By random pixel intensities without any specific arrangement.

By a matrix of intensity values for each pixel.

By three intensity values per pixel arranged sequentially in a vector. (correct)
