Hi, I'm Logan from Harmony Schools. Today, we live in a world where everything
is becoming automated, from banking to food production and even car manufacturing. Thanks
to recent advances in computer hardware, computer vision is taking automation even further.
Computer vision, the use of a computer to analyze image data, can be used to automate
tasks that usually require visual analysis by a person. Computer vision systems can already
be used to automate a variety of tasks. Geographical Information Systems, or GIS, use computer
vision to analyze satellite images and other geographical information. They greatly reduce
the amount of labor that goes in to generating and analyzing the data. Record-keeping, statistical
analysis, and even disaster relief planning can be automated using GIS.
My research focused on implementing a computer vision system to track people. My computer
vision system, like many others, has three main functions: learning, segmentation, and
tracking. First, a target image is used to teach the computer vision system what to look
for. Next, the computer vision system analyzes each frame of video from the camera and attempts
to locate the target. Finally, it tracks the target as it moves around the camera's field
of view. During my research and development, I focused specifically on generating object
descriptors. The problem was: how does the computer differentiate between a person and
other objects in the scene like a tree or a car? The computer has to be able to both
recognize the target image in different orientations and lighting as well as differentiate it from
the other objects in the scene. This is accomplished using an image descriptor called a Histogram
of Oriented Gradients, which describes the frequency of certain patterns within an image.
For more information about how this works, check out my project website or my research
paper. I've put both of these in the description. Computer vision has countless applications.
It's already being used for quality control, GIS, and even Google's experimental self-driving
cars. Thanks for watching this Harmony Schools video.
