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
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!
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.
Bitmap Algorithm :-
Stores image data as a 2D array of pixels, where each pixel has a specific intensity or color value.
It refers the way an image is stored, processed, and analyzed. These are several ways to represent an image including.
Raster Representation:-

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.
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.
