Introduction to Machine Vision
Image processing techniques play an important role in the field of machine vision. Image processing is the process of analyzing and manipulating images to extract useful information. It involves techniques such as filtering, segmentation, and feature extraction.
Filtering is the process of removing unwanted noise from an image. It is done by applying a filter to the image. There are different types of filters such as median filter, mean filter, and Gaussian filter.
Segmentation is the process of dividing an image into multiple regions or segments. It is used to identify objects in an image.
Feature extraction is the process of extracting important features from an image. These features can be used for object recognition or classification.
One of the most commonly used image processing techniques in machine vision is edge detection. Edge detection is the process of identifying the boundaries of objects in an image. There are different algorithms for edge detection such as Sobel, Canny, and Prewitt.
Another important image processing technique is object recognition. Object recognition is the process of identifying objects in an image. It involves techniques such as template matching, neural networks, and decision trees.
It is important to choose the appropriate image processing techniques for a given application. Factors such as image quality, lighting conditions, and processing time need to be considered when selecting image processing techniques. Machine vision systems also need to be calibrated to ensure accurate and consistent results.
Overall, image processing techniques are essential for achieving reliable and accurate results in machine vision applications.
