Nature of Image Processing

 images are everywhere! Sources of images are paintings, photographs in magazines, Journals, image galleries, digital Libraries, newspapers, advertisement, boards, television and Internet.

Images are limitations of Images.

In image processing, the term  'image' is used to denote the image data that is sampled, quantized, and readily available in a form suitable for further processing by digital computers.

cryptocurrency, but do you know exactly what it is and how it works?

 Cryptocurrency

Cryptocurrency is digital money that can be used to buy goods and services, using strong encryption techniques to secure online transactions. Banks, governments and even companies like Microsoft and AT&T are very aware of its importance and are jumping on the cryptocurrency bandwagon!

1 - Cryptocurrency owners keep their money in encrypted, virtual ‘wallets.’ When a transaction takes place between the owners of two digital wallets, the details are recorded in a decentralized, electronic ledger or blockchain system. This means it is carried out with a degree of anonymity and is self-managed, with no interference from third parties such as central banks or government entities.

2- Approximately every ten minutes, special computers collect data about the latest cryptocurrency transactions, turning them into mathematical puzzles to maintain confidentiality.

3- These transactions are then verified through a technical and highly complex process known as ‘mining.’ This step typically involves an army of ‘miners’ working on high-end PCs to solve mathematical puzzles and authenticate transactions.

Once verified, the ledger is updated and electronically copied and disseminated worldwide to anyone belonging to the blockchain network, effectively completing a transaction.

Cryptojacking

Cryptojacking is an emerging threat that hides on a user’s computer, mobile phone, tablet, laptop or server, using that machine’s resources to 'mine’ cryptocurrencies without the user's consent or knowledge.

Many victims of cryptojacking didn’t even know they’d been hacked until it was too late!

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.
