What’s Quantitative Image Analysis?

[ad_1]

Quantitative image analysis involves the use of digital images to provide data and information. This is done with computer technology to recognize patterns, create maps and process signals within images that cannot be done with the human eye due to the large amount of information generated and collected. There are many different methods for quantitative image analysis, including medical scanning, object recognition, and three-dimensional modeling techniques. The techniques are performed by individuals trained in computer engineering, computer vision, and image analysis, who understand how to use technology to analyze data.

Some types of images are difficult to analyze without the use of technology, which is why quantitative image analysis is performed. For example, in some medical fields, images can be used to find information about what is happening inside a person’s body that could otherwise only be found through surgery. In security, quantitative image analysis is used to identify people’s faces and help eliminate security threats. There are many other applications of quantitative image analysis that are useful in various situations and for finding different types of information.

The data that is collected from the images is analyzed using sophisticated statistical and modeling techniques, depending on the end use. Some situations require a three-dimensional model that provides information that would otherwise be very complicated, expensive and time-consuming to find. In other situations it is more useful to have graphs, charts, and other quantitative information that can provide insight into ongoing trends. Other techniques involve analyzing extremely small images that contain a large amount of information by looking at the spatial intensity of pixels in an image.

Information is found through quantitative analysis of images with methods such as wavelengths of light, cross-sections of materials, and video, depending on the purpose of the analysis. Once the images have been collected, they are then processed via computer to calculate the data into binary code which can be further analysed. Images can be edited, manipulated or transformed easily because the computer software used is very advanced and technical.

Image analysis occurs in different fields from statisticians, computer scientists and engineers. Individuals involved in this line of work generally have advanced degrees in the subject in order to understand the complicated computer programming and statistical techniques required to make sense of the vast amount of data. As new technology is constantly being developed, the field of quantitative image analysis continues to change and grow on a regular basis.
