Image Processing Techniques and Concepts

The video tutorial explains the process of image convolution using a 3x3 grid of values. It describes how each value in the grid is multiplied by the corresponding pixel it overlays, and how colors are represented as RGB vectors. The process results in an average along each color channel, creating a blurred version of the original image. The tutorial also covers the technical aspect of convolution, including the use of a 180-degree rotated grid.

What is the purpose of the 3x3 grid in the image processing technique described?

• To add noise to the image

• To multiply with corresponding pixel values

• To enhance the image colors

• To change the image resolution

How are colors represented in computer science according to the video?

• As single values

• As hexadecimal codes

• As vectors of three values

• As binary codes

What is the result of averaging the color channels in the image processing technique?

• A grayscale image

• A sharper image

• A pixel with increased brightness

• A pixel defined by the sum

What is the overall effect of applying the described image processing technique to every pixel?

• The image colors are inverted

• The image resolution increases

• The image becomes sharper

• The image becomes blurrier

What term is used to describe the process of applying the grid to the image?

• Erosion

• Dilation

• Transformation

• Convolution
