Computer Vision

How does it work?

Machines understand process and analyze images with the information it can access on the topic. With the neural networks, the iterative learning process can be set. If you are looking forward to identifying the forest area all over the globe, the datasets used by neural networks require images and videos of green patches and dry patches. Tagged images and metadata helps the machine to reply correctly. Different pieces of image are recognized using pattern recognition by the neural networks.

Mainly the system uses various components of the machine vision system such as lens, image sensors, lighting, vision processing, and communication devices. Computers assemble visual images in bits like a puzzle put together. The pieces assembled into an image makes filtering and processing speedy. In the above example of identifying forests, the machines are not trained to see different tree types and leaves instead they are trained to recognize the green patches on earth. The training lets it create an image of the forest and match it with the data.

Deep Learning learns from large amounts of data and its algorithms are inspired by a human brain to result most accurately. This subset of machine learning can identify objects, people, tag friends, translate photos, translate voice, and translates text in multiple languages. Deep learning has transformed computer vision with its high level of accuracy that is beyond human capacity.

Difference between Computer Vision and Machine Learning:

Machine learning helps the computer to understand what they see and computer vision determines how they see. Machine learning is where the systems teach themselves based on the continuously populating data. CV requires artificial intelligence to train the system in performing varied tasks. CV does not learn from the training data available but makes data patterns to find relations between data and understand it for a visual representation of a preset result.
Computer vision is progressing towards replacing human vision that assists in complicated tasks. This requires intelligent algorithms and robust systems.

Examples of Computer Vision Applications:

Applications of Computer Vision

Augmented Reality:

  1. Geo Travel: Augmented Reality Geo Travel can be your travel guide, GPS enabled application gives you information on your exact location. Plan a trip for you using your searched data on the city with the result of Wikipedia pages that you can save for easy travel. Find a car with a car finder that saves your parking position for you to get back to your car easily.
  2. Web: The Augmented Web combines HTML5, Web Audio, WebGL, and WebRTC to improve the user experience when they visit existing pages. Image search, Google photos use face recognition, object recognition, scene recognition, geolocalization, Facebook takes care of image captioning, Google maps use aerial imaging and YouTube does content categorization with help of computer vision.

Automotive: In this field can save millions of people from tragic traffic accidents. Human error is possible due to multitasking, overthinking, tension and negligence. Self-driving cars are loaded with multiple cameras, radar, ultrasonic sensors and technology that detect 360-degree movement, developed by Google Labs. Tesla car warns drivers to take control of the steering wheel. The error proofing, presence, and absence of objects, responsible control on the machine all is possible with computer vision. Technology takes control by detecting objects, marks lanes, catches signs and understands traffic signals for us to drive safely.

Agriculture: Computer vision can check the quality of grain, identify weeds, and take actions to save crops by sprinkling herbicides on weeds using AI technology. It helps in the packaging of agricultural produce and products.

Healthcare and Medical Imaging: This technology helps healthcare professionals inaccurate presentation of data, reports, and illness-related information. It can save patients from getting improper treatments, study their medical data, which is image-based such as X-Rays, CT scans, sonography, mammography, and other monitoring activities of patients. Augmented Reality assisted surgery ensures better results than surgeries with human surveillance.

Get assistance in surgery from the analysis of various images with computer vision technology. Gauss Surgical is a blood monitoring solution that closely watches blood loss in real-time. It can save patients’ life during critical operations, facilitate blood transfusions, and make out hemorrhage. The images captured with help of iPad or Triton, processed by cloud-based computer vision and it estimates blood loss through intelligent machine learning algorithms. Computer vision can improve diagnosis ad automate pathology.

Smartphones: These handy tools for perfect pictures and AI are transforming the arena of development in computer vision. It scans QR codes, has portrait and panorama modes of photography. The face and smile detection, anti-blur technology is computer vision.

The accurate recognition of any sign is possible due to optical character recognition and augmented reality for exact translation.

Challenges of Computer Vision:

Challenges of Computer Vision
  1. The human visual system is too good to be simulated. The capacity of the human eye and brain in coordination with each other can recognize things, people and places are better. Computer systems can fail to recognize the faces with a variety of expressions or variant lighting.
  2. Initial research for industry-specific tasks can be expensive. The technology is changing rapidly but the complexities of integrating computer vision systems are a higher-level challenge.
  3. Face recognition is an annoyance and breach of privacy and business ethics in the hospitality, finance and banking industry. Multiple and adverse uses of technology are a threat and San Francisco has banned facial recognition.
    The algorithms for each talk about a particular industry may not be accurate or updated and the results may not match the preordained results.
  4. The misuse of computer vision is the result of faulty inputs or intentionally tampered images to form flawed patterns that harm the learning models.
  5. Object classification is challenging as the label is assigned to the entire image for classification. Handwritten documents are difficult for computer vision, due to a variety of handwriting styles, curves and shapes formed while writing for each alphabet.
  6. Object Detection is more complicated than image classification as there can be multiple objects in an image and the request can be for single objects or combinations.

Insufficient visual data sets or image reconstruction used to fill in for the missing parts of the image damages or corrupts the versions of photos.
