Computer Vision

I always prefer to write Article in simple and easy way to understand the fast

growing concept in the globe. In the concept of these, I wrote many of concept

of AI related before. You can read all of them from my blog (POPULAR POST) 
option. As far as concern about the Computer vision it also the part of AI, 
and a lot of research is going on this. In this Article we are going to understand
 about in very easy and simple way.

I also insist you to attempt the quiz which is present in the last of Article.

First word

       Computer Vision derived from Artificial intelligence and Computer science, this concept giving the virtual concept of the world in the form of images understanding! Would that Computer can see and observe, it is the dream of past where our desire to do our computer work as like human after seeing the object. But in this modern world it’s become true in the form of Computer Vision.

So, what is Computer Vision?

How does it work?

From these and related question arise in our mind.

       In this Article we are going to understand the concept of Computer Vision from basic introduction

Let’s assume I give you an image in which different living and nonliving things are present, as human we can easily identify the human and animal also others nonliving thing like floor, wall, frame and others which is represent in the background of the image.  Also we can write a complete novel on it after observing the image from depth.

      The Concept of understanding the image and identify the character on it, is called Computer Vision.  Actually it the concept of seeing the computer as like human, using this concept we are trying to make computer intelligent as like human to identify the character from images.

How does it work!

Using three basic component computer vision does it work with digital images.

Image acquisition

Image processing
Image analysis and understanding

The flow diagram of these process:

Let’s understand these three individually.

Image acquisition

Image acquisition is the process of translating the analog world around us into binary data composed of zeros and ones, interpreted as digital images.

In the process of image acquisition we convert the analog image into binary data which composed it into 0’s and 1’s, like digital images.

For this process different tools have been used

Like webcam, digital camera, modern DSLR, 3D cameras, laser related camers.

Image processing

In the part of image processing, image is changed into geometrical element to build and show the basic structure of the images or object using low level processing. For basic understand if you used the PHOTOSHOP you did this work many time using different option on it. We used this effect on our images but we don’t know about them. Actually these  happened on it using advance mathematical algorithm and the images processing effect.

Few of these techniques are:

1. Edge detection
2. Segmentation
3. Classification
4. Feature detection and matching

Edge detection

Segmentation

Classification

Feature detection and matching

Image analysis and understanding

Computer vision last step is identify the object from data, where machine finally take the decision in term of output using advance algorithm. The step complete their work using previous steps (image date, and low level information).

High-level image analysis are:
1. 3D scene mapping
2. Object recognition
3. Object tracking

3D scene mapping

Object recognition

Object tracking

Applications of computer vision

In the field of computer science, AI, robotics, human-computer interaction and images visualization different application are doing their work, few of are:

Horizon with Computer Vision 

Diseases identification using Computer vision

Image restoration such as denoising

Computer Vision on the Horizon

Motion recognition

Computer Vision in Industrial Preventative Maintenance
Augmented reality
Autonomous cars

Thanks for reading, I am hopeful it is very informative for you. It's also good thing for you after ready to attempt the quiz, TRY IT TO UNDERSTAND YOU KNOWLEDGE. Do and understand about your knowledge.

Git Vs Github understanding and Advancement on them!

Hi, Well come to Fahad Hussain Free Computer Education!

As a Computer Scientist I always prefer to express my knowledge 

around the globe FREE. A lot of tool, software and application are 

being used around the globe and we are using this according to

the market trend and need. GIT AND GITHUB in one of them.

I know many folks know about the usage and definition But 

I personally observed many person don’t know about the 

DIFFERENCES  BETWEEN THEM, 

and many of developer even failed to express their word in term

of differences, but they are using this.

So, in this Article we are going to understand the

DIFFERENCES BETWEEN GIT AND GITHUB.

So, Let’s understand…

       As a developer or programmer often time we need to share our code with our team member to make your project more perfect according to the demand. For this we used to use Google Drive and related cloud base software when we update or change the previous code but here is no option to Version Control on it  we just replace the code and finally we lost the existing code which were be the part of your project before. To secure the previous code and capability to control the version GIT and GITHUB are being used in the IT industries these days.

I am pretty sure many of you know about GitHub and also you are user of it but only few of them know about the difference between Git and Github!

So what are they?

Why we use it?

What are the differences between them?

And can we survive in IT field without this technology?

       In this Article we going to get the answer of these most frequently asked question which has been asked in interview as well.

But first we need to understand the word Version Control

Version Control:

         

          Let’s consider 3 person are working on project and these three doing work on JavaScript file at the same time, unwilling they made the function by the same name but different in work. When the code merge it is an obstacle thing to identify the error in less time. In industry point of view TIME IS MONEY, and if you expend more time to find an error what will be the max time to make a whole project? So a Version Control who enable us to control the version and keep track the changes in the file time to time and finally make it repository. Also the feature to come back to previous it provides. A repository (folder) is central place where the records are saved in the organized way. A way of this Version control is really helpful for big project where the numerous of person do work on the same project.

Let’s see the practice example of Version control in industrial work.

We were finding that kind of system which make our work easier, for this we are using Version Control System. The picture demonstrate the concept of Version Control using three broad way Time, project and DataBase. Time creates the basic history when any developer submit the code using Version Control in the Project were DataBase (VCS) hold the history of the file including the developer comment (which type of work has been done by him/her). By using VCS we can see the previous file and also another file which has been modified by another developer which make our work easier and faster and easy to compare. 

GIT:

It’s a version Control System also a software, which mange your source code history in your computer. It has been designed by Linus Torvalds, after the frustrated with the past proprietary software, as like other version control like subversion or CVS it is similar. It is best system when you are working on your own project and you need to find the history of you project it will provide stunning service. For getting this service we need to install in on your machine.

It is also called DISTRIBUTED VERSION CONTROL SYSTEM means using this system we can apply different operation like push and pull in other’s user machine. Git provides to access the same file’s copy as your project’s member, But it does not reflect any changes in the main directory unless or unless you applied any operation like push and pull on it. The basic benefits of Git: 

Backup
            Free and Open Source
            Fast & Small
            Easier Branching

GITHUB:

     

 Now a days, numerous of developers are used Git in different organization to build their own project. As a picture demonstrate us the latest trend of Git usage in the market and showing it popularity. Ahead from 2005 the Git grow its market through it version control system and including America and related country, it’s important in term of usage and saving time.

Github:

          Actually GitHub is a hosting service for Git Repositories and it is service for the project that use Git. UI of Github make it more attractive for user. Github is used to get connection with Git and allows user to save their code not in your local machine as like Git, it provide you to save your code online also give access to connect with different user/developer on different project. Its provide bug tracing, feature request and task management. In simple word we can say that Github provide us the collaboration tool which provide the connection between users/developer and also them to share their ideas according to their project. It is not end of Github features, Moreover, the additional features make Github more attractive and get attention form developer/users. Let’s discuss.

Pull: When you are going to make changes in your code, and you done it and copied. Now, you want share it like original order, you need pull command this command send a notification of changes.  

Push: commit make on your local branch to a remote repo. It has two argument, a remote name like origin, a branch name, like master.

Fork: Also called forking, when the user has not access to write, he/she fork (copy) the repository from other user account. Now he/she can make changes on it in local machine.

Merge: by using this command user merge the active file with previous file only who is the owner of the code where did he makes changes.

Basic comparison:

Git	GitHub
Work like as a software	Whereas Github is a service (online)
Need to install on the local machine	Whereas Github hosted on web.
Support command line tool	Whereas Github provides UI for their user
Using Git we can manage different version for Git repo.	There is a space to upload copy of the git repo.

I am hopeful this Article will be beneficial for you!
