The terms “computer system vision” and “image processing” are utilized practically interchangeably in lots of contexts. They both include doing some computations on images. However, are they the very same thing? Let’s discuss what they are, how they are various, and how they are linked to each other.
Image processing concentrates on, well, processing images. What this means is that the input and the output are both images. An image processing algorithm can change images in numerous methods: smoothing, honing, altering the brightness and contrast, highlighting the edges, and so on.
Computer vision, on the other hand, concentrates on making sense of what a machine sees. A computer vision system inputs an image and outputs task-specific knowledge, such as item labels and collaborates.

Computer Vision And Image processing
Computer vision and image processing work together in a lot of cases. Lots of computer system vision systems count on image processing algorithms. Computer vision systems rarely use raw imaging data that comes straight from a sensor. Instead, they utilize images that are processed by an image signal processor.
The opposite is also possible. It wasn’t typical for an image processing algorithm to depend on computer vision systems in the past; however, more and more sophisticated image processing approaches have begun to utilize computer system vision to improve images. Face beautification filters, for instance, use computer system vision techniques to identify faces and apply smoothing filters such as a bilateral filter selectively. They can do advanced things, such as enhancing eye clearness or imitating a spotlight by spotting facial landmarks and tuning the images in your area. I know the result you see on the right does not look good. It looks very artificial. I did it on function, though, to show the distinction better.
Another essential quality of computer system vision is making use of artificial intelligence. We have spoken about artificial intelligence in the earlier videos; however, if you are not familiar with the idea, it’s a discipline that focuses on mentor devices how to perform a certain task given a set of examples. For instance, we can construct a design that can tell the difference in between a cat and a pet dog after being trained on photos of cats and pets.
It’s true that computer vision greatly counts on machine learning; however, that’s no longer a differentiator. Many advanced image processing approaches likewise use machine learning models to transform images to achieve a variety of jobs, such as using creative filters to an image, tuning an image for optimal effective image quality, or enhancing details to make the most of the performance for computer system vision tasks.
It’s worth discussing that there isn’t a tough line in between these two fields. The line in between computer vision and image processing gets fuzzy when you do pixel to pixel changes. Let’s take semantic segmentation as an example. If a model produces per-pixel labels for an input image, then its output can be considered as an image. In that sense, the design would be doing some sort of image processing. On the other hand, because such a change includes image understanding, attempting to understand what’s in the input, it would also be considered computer system vision. Overall, I think I would still think about semantic segmentation more of computer vision than image processing; however, you understand.
Another example of the interplay in between image processing and computer system vision would be using Convolutional Neural Networks or CNNs for short. CNN’s typically take pixel intensity worths as inputs and find out to process them in a way that makes it possible to achieve a certain computer system vision task, such as image acknowledgement. The output of such a model can, for instance, be a label that explains what’s in the input image. Internal layers of CNNs can be thought about as image filters with tunable criteria. What a CNN does can be thought about as some adaptive image processing. Using CNNs is not restricted to image processing, though. They can be utilized to process and evaluate other kinds of information as well.
CNN’s do a fantastic job at vision, audio, and even natural language processing applications. Scientists and engineers have built remarkable applications using CNNs. If you wish to learn more about how they work, check out my earlier videos in the Deep Learning Crash Course series.
