Raster Representation Algorithms

 Bitmap Algorithm :-

 Stores image data as a 2D array of pixels, where each  pixel has a specific intensity or color value.

Image Representation

 It refers the way an image is stored, processed, and analyzed. These are several ways to represent an image including.

Raster Representation:- 

• Known as Bitmap representation.
• Image is represented as a 2D array of pixels.
• Each Pixel has a specific intensity or color value.
• Commonly used in digital images, graphics and video.

Vector Representation :-

• Image is represented using geometric shapes and lines.
• Uses Mathematical equations to draw shapes and lines.
• Commonly used in graphics, CAD and illustration software.

Frequency Domain Representation :-

• Image is represented in the frequency domain using fourier transform.
• Shows the frequency components of the image.
• Useful for image filtering compression and analysis.

Image Attributes:-

Intensity :- Refers to the brightness or darkness of a pixel.

                  Typically represented as  grayscale value (0-255).

Color - Refers to the combination of red green and blue values.

            Can be represented using different color models (RGB, CMYK , HSV).

Texture:- Refers to the pattern or arrangement of pixels in an image.

                Can be used to analyze and classify image.

Data Cummunication System

 Data communication is the exchange of data between two or more devices via a transmission medium. The communicating  devices in a data communication system are referred as nodes or workstations.

The Transmission media used for communicating between devices are referred as communication channels or links.

Effectiveness of data communication depend upon these characteristics.

Delivery:- data must be deliver to the correct destination.

Accuracy:- data must be deliver accurately 

Timeliness:- data must be deliver in timely manner.

Multimedia

 

What are Multimedia System

Multimedia refers to the integration of multiple forms of media such as text, audio, images, animations, and video to create a comprehensive and engaging experience. The scope of multimedia is vast and encompasses various applications, including education, entertainment, advertising, and more.

"A multimedia system is responsible for developing a multimedia application. A multimedia application is a bundle of different kinds of data. A multimedia computer system is one that can create, integrate, store, retrieve delete two or more types of media materials in digital form, such as audio, image, video, and text information."

Types of Images

 The Binary Image:- As one could have guessed, binary is all about 0's and 1's.

A binary will contain only two colors. 

One being white and the otherr being black.
