Computer vision is basically an interdisciplinary field that deals with how computers can be made to gain a high-level understanding from digital images or videos.
With computer vision, your computer can extract, analyze and understand useful information from an individual image or a sequence of images. Computer vision is a field of artificial intelligence that works on enabling computers to see, identify and process images in the same way that human vision does, and then provide the appropriate output.
Computer Vision is the same as imparting human intelligence and instincts into a computer.
Sounds simple, right?
Well, technology isn’t although the concept is simple. It is a difficult task to enable computers to recognize images of different objects.
For better understanding, imagine whenever a machine processes raw visual input – such as a JPEG file or a camera feed – it’s using computer vision to understand what it’s seeing. Think of computer vision as the part of the human brain that processes the information received by the eyes – not the eyes themselves.
As a scientific discipline, computer vision is associated with the theory behind AI systems that extract information from images. As a technological discipline, computer vision seeks to apply its theories and models for the construction of computer vision systems.
Sub-domains of computer vision include scene reconstruction, event detection, video tracking, object recognition, 3D pose estimation, learning, indexing, motion estimation, and image restoration.
The concept of computer vision was first introduced in the 1970s. All these new applications of computer vision excited everyone. Having said that, the computer vision technology advanced enough to make these applications available to everyone at ease today.
However, in recent years the world witnessed a significant leap in technology that has put computer vision on the priority list of many industries.
As mentioned earlier, computer vision plays a crucial role in the advancement of technologies, especially AI. The applications of computer vision, in particular, are very versatile and never-ending.

From something as basic as convenient stores to healthcare, computer vision is being implemented everywhere.
That’s right, no more waiting in line to pay the bills. It’s a partially automated store and by utilizing computer vision, deep learning, and sensor fusion customers are able to simply exit the store with products of their choice and get charged for their purchases through their Amazon account. Amazing, right?
They are equipped with sensors and software that can detect 360 degrees of movements of pedestrians, cyclists, vehicles, road work, and other objects. They are able to follow the traffic flow and regulations and can detect obstacles in its way.
One of the most recent and exciting medical procedures involving computer vision is a real-time blood monitor by the Gauss Surgical company, that solves the problem of inaccurate blood loss measurement during injuries and surgeries. It maximizes transfusions and recognizes hemorrhage better than the human eye.
Both computer vision and image processing are based on the input of an image or signal and then processing the signal to give us the altered output. As their names already imply their goals and methodologies, the boundaries of these two fields may seem clear. However, they draw heavily from the methodologies of one another, which can make the boundaries between them blurry and people confused between the two.
To put out simply, image processing is a subset of computer vision. A computer vision system uses the image processing algorithms to try and perform its functions.
As the name suggests, in image processing an image is processed. The image is bettered. It may have something to do with smoothing, sharpening, contrasting, stretching etc. It makes the image more enhancive & readable. Also, input and output are both images.
The ultimate goal of computer vision is to use computers to emulate human vision, including learning and being able to make inferences and take actions based on visual inputs. Computer vision is not limited to pixel-wise operations, it can be a lot more complex than image processing. The input can be both images or videos, and the output is not necessarily an image but can also be quantitative or qualitative information, like size, color, shape, classification, etc.
Therefore, if the goal is to enhance the image for later use, then this may be called image processing. And if the goal is to recognize objects and provide useful information on it then it can be called computer vision.
As you already know, there is a lot of overlap between computer vision and image processing. Machine learning, on the other hand, is flexible as it can be used in both computer vision and image processing. Machine learning is an application of artificial intelligence that provides systems with the ability to automatically learn and improve from experience without being explicitly programmed. The goal of machine learning is to optimize differentiable parameters so that a certain loss/cost function is minimized.
Machine learning can be used in both image processing and computer vision but it is found to be more useful in computer vision than in image processing.
Computer Vision has the power of complex image processing techniques to extract meaningful features from a given image or video samples whereas machine learning deals with pattern recognition and computational learning using sophisticated data-prediction algorithms, artificial neural networks, etc.

3. Facial Expression Recognition Project:
Imagine a project where a machine can detect a person’s facial expression and even display whether he/she is smiling, sad or shocked. Sounds fun, right?
This software system is designed to first detect and read a person’s face. The system then computes a number of facial parameters of the person.
After detecting these parameters, the system compares them with default expressions for sadness, smile, and others. Based on the statistics, the system concludes the person’s emotional state. Visual Studio and SQL Server are some of the technologies that are used and you can gain knowledge on them.
4. Cursor Movement by Hand Gesture Project:
Imagine if you could control cursor through hand gestures. It sounds really intriguing, doesn’t it?
Well, this project puts forward a system that allows the user to control the mouse movements through the use of hand movements only. No need to use a mouse anymore. The implementation of this project will be really useful in large scale industries and offices
The system uses a webcam in order to detect hand gesture movements. It continuously scans the camera input for five finger hand like patterns. Once a hand is detected, the system then locks it as an object. After the object has been flagged and detected, the system then constantly records its movements in terms of X-Y direction movement based coordinates. These coordinates are then mapped real time onto the mouse cursor to move it according to hand movements.
5. Theft Detection Device Project:
Are you paranoid about your safety? If you are, there is no surprise. Everyday theft is increasing and having a machine that can detect thieves will undoubtedly come in handy.
This device helps to secure your homes and offices from theft. It uses image processing on live video to detect theft using motion. It also highlights the area where theft occurs.
It allows the user to view the theft details and saving the video of the theft in a USB drive. In this system, a camera along with a circuit LCD, display IR for night vision and a USB drive for storage is used. As soon as the camera detects motion, the system uses image processing to identify the exact area of motion occurrence and then highlights it accordingly. The system now transmits the images of the occurrence over the internet to be viewed by the user online.
You can gain so much knowledge on image processing algorithms its and Raspberry Pi by doing this project.
6. Camera Motion Sensing Project:
This motion sensor project detects motion in a particular environment and sets off an alarm accordingly. It is like having your own CCTV camera. The only difference is you would be the one who built it.
This software system is designed in C that constantly monitors an environment using a camera. It even records images of the motion taking place as soon as it is detected.
You first need to set a security code. As soon as the user sets the code and activates the system, the monitoring starts.
The motion detector algorithm now constantly monitors the environment to check for any movement.
As soon as any movement takes place in front of the camera the alarm is activated. The user can deactivate the alarm by entering the security code again.
7.Look Based Media Player:
Remember those moments when you're completely immersed in a movie you're playing on the laptop and then you get an urgent call? And you miss important parts while answering it and you have to rewind again to the part where you exactly left it off. Sounds irritating, right? Well, it is. However, here is a solution to this problem.
A look based media player that pauses itself when the user is not looking at it and resumes as soon as the user looks at it again.
This is done using the camera or webcam on top of the computer. As long as the camera detects the user’s face looking at it, the media will be played. The player pauses as soon as the user’s face is not completely seen. This way you won’t miss any emotional drama from your favorite movie.
