At present, most of the mainstream Ethereum mining machines in the market are from Bitmain and Canaan. However, with the decline in the price of Ethereum, the profit brought by mining has been very meager. Investors can choose to trade Ethereum in digital currency exchanges. Square trading investment. At present, the mainstream digital currency exchanges in the market are Binance, Huobi, Bitnet, etc.

“Wu” what does blockchain nft mean

Hello, the full name of NFT is Non-FungibleToken (non-fungible token), we generally see is a homogenized token. For example, 1 BTC in your hand and 1 BTC in other people’s hands are the same, with the same anchor value and can be exchanged at will.

Fiat currency is a homogeneous currency. For example, a $5 bill is completely interchangeable with any other $5 bill. Likewise, cryptocurrencies such as Bitcoin and Ethereum are interchangeable, i.e. 1 BTC can be swapped with 1 BTC, 1 ETH can be swapped with 1 ETH, and so on.

On the other hand, NFTs rely on special token standards such as ERC-721 to ensure uniqueness. Driven by blockchain technology, NFTs are not interchangeable and have verifiable uniqueness and scarcity.

Non-fungible tokens (NFTs) are unique tokens in the vernacular. Even in the same system, NFTs exist independently. And NFT is not like BTC and ETH which can be divided into 0.1 or 0.0002, the unit of NFT is always 1! NFT features: unique, not splittable.

In this sense, NFTs are like digital collectibles or proofs of ownership, they are valuable precisely because they are 1:1 or limited edition An asset with liquidity and utility on the Ethereum platform.

In 2017, with the launch of collectible items such as CryptoPunks and CryptoKitties, the NFT ecosystem began to enter the public eye. Since then, the field has blossomed towards a variety of new use cases and industries. According to analytics site NonFungible.com, the NFT economy has seen over $109 million in token sales to date, including $1 million in the last week alone!

Different Types of NFTs
NFTs can tokenize almost anything, especially various media types are achievable goals. By far, the most common use cases for NFTs are:

Digital art (SuperRare, KnownOrigin, Async Art, Rarible, etc.);

Digital music (Mintbase, InfiNFT, etc.) ;

·Virtual real estate (Cryptovoxels, Decentraland, etc.);

·VR wearable devices; NFT (Non-Fungible Token) defines an ecologically inseparable, Unique interface specification for token interaction and circulation. On the blockchain, digital cryptocurrencies are divided into two categories: native coins and tokens. The former, such as Bitcoin, Qtum, etc., are for reference only.

『柒』 Can you explain Ethereum in a simple way

Ethereum is not actually a currency, it is a way to Centralized smart agreement. It can be understood as a huge global ledger. The logic of this smart agreement does not require a specific server to support its daily operation in execution, but instead is the agreement terms given by the automatic executors between scattered users before entering. This is an application that evolved from decentralization.
Comparing with Bitcoin, we can find that Ethereum establishes a new type of encryption technology, and its program development difficulty is simpler than Bitcoin. This breakthrough greatly reduces development costs and development time for developers applying blockchain technology. The emergence of Ethereum once again reiterated the necessity of splitting and centralizing, as well as the feasibility and advantages of decentralizing distributed applications, giving the existing economic market and financial industry a new development direction and throwing a new direction to the society. New entrepreneurial ideas and opportunities.

What is the source of “渌” NFT

In 2017, the blockchain game Cryptokitties (Cat Obsession) rapidly became popular

『玖』What is Ethereum

People in the circle are very familiar with Bitcoin. Bitcoin has created a precedent for decentralized cryptocurrency, but Bitcoin is not It is not perfect, and there are many criticisms that are difficult to solve. However, the birth of Ethereum solved the problem of insufficient scalability of Bitcoin.
Ethereum is an open-source public blockchain platform with smart contract functions, providing a decentralized ether virtual machine through its dedicated cryptocurrency ETH to process peer-to-peer contracts.
It provides various modules for users to build applications. If building an application is like building a house, then Ethereum provides modules such as walls, roofs, and floors. Users only need to build the house like building blocks. , so the cost and speed of building applications on Ethereum are greatly improved. Specifically, Ethereum builds applications through a set of Turing-complete scripting languages, referred to as EVM language, which is similar to assembly language.

“Pick up” image processing experts are invited! May I ask what is the mean-shift image segmentation technology and what is the principle of it, thank you!

I searched the Internet, but I haven’t found an article that clearly explains the principle of mean shift, so I will write a paragraph:

First of all, you must know that this is from PAMI 2003 An article, very classic, Mean Shift: A Robust Approach Toward Feature Space Analysis. Of course, the original text has 17 pages, all of which are complex formulas. . . . .

Mean shift is mainly used for image smoothing and image segmentation (that tracking I don’t know yet), first introduce the smoothing principle:

The input is a 5-dimensional space , 2-dimensional (x, y) geographic coordinates, 3-dimensional (L, u, v) color space coordinates, of course, your principle can also be rewritten into rgb color space or texture feature space.

Let’s first introduce the kernel function, there are uniform and Gaussian kernel functions, no matter which one is, the basic idea is as follows: a simple smoothing algorithm uses a template to average, and for all pixels, use The surrounding pixels are averaged and it’s done.

This mean shift is based on the probability density distribution, and it is a non-parameter sampling. Sampling with parameters isAssuming that all samples obey a probability distribution function with parameters, such as Poisson distribution, normal distribution, etc., high school students know that there are parameters in the probability formula, let’s talk about the feature space is a 5-dimensional space, the distance You can use Euclidean space, at least that’s how the code is implemented, and the parameterless sampling in this article is like this: there is a 3-dimensional window in the feature space (imagine a 2-dimensional window), for a feature A point in space corresponds to a 5-dimensional vector, and a density function of the point can be calculated. If the coordinates of the point are directly brought in with parameters, the probability density can be calculated. The idea based on the window function is to consider its adjacent window. The contribution of the points in it to it. It assumes that the density will shift to a denser place, and calculates a 5-dimensional coordinate after the movement. The coordinate will be stable. After several iterations, the stable place is the modes. In this way, each pixel corresponds to such a mode, and using the last 3-dimensional value of the point is a smooth result. Of course, when calculating each point, some parts may be repeatedly calculated. If you are interested, you can refer to Look at the source code, it can indeed be optimized. To sum up, the smoothing principle of mean shift is to shift (transfer) to a higher density in the feature space.

Secondly, how to use mean shift to segment the image

First smooth the image,

The second step is to use the smoothing result to establish a region adjacency matrix or region The adjacency linked list means that two pixels that are relatively close in the feature space and relatively close to the 2-dimensional image plane are counted as an area, so that the adjacency linked list corresponding to an area records the label value of each pixel point. Of course, there is a calculation of transferring convex cells in the code, merging two adjacent areas with very close surface tension. I haven’t figured out how to understand this, and I hope a clearer friend can talk about it. Finally, there is an operation of merging regions with a smaller area. A region does not correspond to a mode value. In the smaller region to be merged, find all adjacent regions, find the region with the smallest distance, and merge into that region. It’s ok.

void msImageProcessor::Filter(int sigmaS, float sigmaR, SpeedUpLevel speedUpLevel) This is the smoothing operation, sigmaS is the window function of the 2-dimensional plane window, sigmaR is the window function of the color space, the last parameter Indicates whether to speed up the algorithm.

void msImageProcessor::FuseRegions(float sigmaS, int minRegion) This is a function that merges smaller regions.

void msImageProcessor::Segment(int sigmaS, float sigmaR, int minRegion, SpeedUpLevel speedUpLevel) This is the segmentation function, which includes the smoothing function. I won’t go into detail. . . . .

The last question is how to call: void CImageProcessing::mydebug()
{
int x,y;
int width_ = imageWidth;
int height_ = imageHeight;
unsigned char *tmp = new unsigned char[width_ * height_ * 3];
unsigned char *dst = tmp;

for (x = 0;x < imageHeight; x ++)
for(y = 0;y < imageWidth; y++)
{
//Color tmp = (*imageData_RGB)(y, x);
//uchar * data = &CV_IMAGE_ELEM(ip,uchar,x,y*3) ;
// *(dst++) = data[2] ;
// *(dst++) = data[1] ;
// *(dst++) = data[0] ;

*(dst++) = (*imageData_RGB)(y, x).channel[0];
* (dst++) = (*imageData_RGB)(y, x).channel[1];
*(dst++) = (*imageData_RGB)(y, x).channel[2];
}
cbgImage_->SetImageFromRGB( tmp, width_, height_, true);
delete []tmp;

msImageProcessor *iProc = new msImageProcessor();
iProc->DefineImage (cbgImage_->im_, COLOR, height_, width_);
iProc->SetSpeedThreshold(0.1);
iProc->Segm ent(5,8,10,NO_SPEEDUP);
// iProc->Filter(5,8,NO_SPEEDUP);
// iProc->FuseRegions(mWinSize,mAreaSize);//°ë¾¶ ºÍ×îС ÇøÓòÃæ»ý
} As for how to debug and compile, I can’t tell. . . . . . . . . . . . . . . . . . . . . .
