Image processing

 What is image quantization? why it is important?

Image quantization is process of converting the continuous range of pixel value into a limited set of discrete value. This step follows sampling and reduces the precision of sampled values to manageable level for digital representation.

DSA day by day preparation in two months

welcome! 

we are going to start a full dsa tour where we learn from the base to intermediate i know my some of time my spellings are not correct but i know the knowledge can make the differences between them. so lets going into deep

dsa mean Data Structure And Algorithm

 

data structure - data and the structure means ?

algorithm ?

write the correct answer in the comment section i want to know the numbers of students who want to learn the DSA.

after this post i start the journey to complete the DSA course with related languages like Java, Python, C++ and other languages on your demands. 

now its your turn write comments and i make sure everyone is ready to involved in this journey

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.

Introduction of Java

 What is Java??

Java is object oriented, platform independent programming language.

Java crash notes

 You want to learn java?

Then you are in right place. I will teach you how to understand the basic to advance in java 

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.

what is a pixel

 one should understand that, image is nothing but, an array or a matrix of multiple pixels which are properly arranged in columns and rows.    

Now, it is also good to understand what a pixel is. A pixel is a word framed from picture element.

"A pixel is the smallest unit in a digital images. Multiple pixels arranged in rows and columns actually from an image. An image is fully composed of pixels."

What is Image Processing?

 Assume a human seeing the above signage on the roads. Immediately, his/her eyes will start capturing the content and brain shall interpret what the signals signify. Based on the understanding, one would make a move further.

In digital image processing, the same image shall be fed in as an input to the system and the system  shall interpret and understand the content to let the further actions happends.

the algorithms developed shall play a major role in understanding the content with higher accuracy.

"Optical image processing is an area that deals with the object, optics and how processes are applied to an image that is available in the form  of reflected or transmitted."

"Analog image processing is an area that deals with the processing of analog electrical signals using analog circuits. The Imaging systems that use film for recording images are also knows as analog imaging systems.
