Home automation system refers to automatic and electronic control of household features, activity, and appliances. In addition, home automation is a network of hardware, communication, and electronic interfaces, which work to integrate smart devices with one another via Internet. Every device has sensors and is connected through Wi-Fi, so anyone can manage them from a smartphone or tablet. This allows to turn on lights, lock doors, or even turn down heat remotely. Home automation and controls system is an automatic centralized control system. This system finds application in heating, ventilation, & air conditioning; lighting; and security & access control. Increase in demand for energy efficiency and maintenance of secure & safe environment with enhanced user convenience in various industry verticals boost the market growth.

Machine vision in the healthcare sector used to offer imaging-based automatic inspection and analyze the image for application such as process control and robotic guidance. Surge in adoption of artificial intelligencebased technologies and big data in healthcare, rise in demand for automation in healthcare applications, and increase in adoption of personalizes medicines are some of the factors that drive the growth of the machine vision system market. However, a shortage of skilled professionals is acting as restrain and hampers early adoption in developing countries. Further, the adoption of cloud-based healthcare solutions is expected to provide lucrative opportunities for the global machine vision industry during the forecast period.

Barcode reader is a device that reads and scans barcode using a laser or the imager. The barcode reader consists of a light source, sensor, and a lens that converts optical impulses into electrical. These readers are available in different size and shape such as handheld, counter top barcode reader, and portable. They are can read 1Donedimensional and two-dimensional (2D) codes based on its design. Laser scanners are mostly used to read onedimensional code. 2D barcode readers are able to read dot matrix and QR codes.

The Food and Agriculture Organization of the U.S. predicts that the global population is expected to grow by over 30% by 2050, reaching approximately 9.72 billion individuals. For increasing overall food production to cater to the growing population, farmers need to implement advanced precision farming processes that enable them to produce more crops and efficiently. The changeability of the climate require solutions that can deal with all biophysical and useful variables in their complexity. In recent times, remote sensing technologies have evolved exponentially due to continuous technological advancements with the spread of multispectral cameras. Hyperspectral imaging is a technology for developing and analyzing an image of a real scene in order to obtain quantitative information for quality assessment and process control. In hyperspectral imaging, the image is split into tens or hundreds of colors.
