Image Segmentation

Segmentation methods in image processing and analysis

Image segmentation is the process of dividing an image into multiple parts. This is typically used to identify objects or other relevant information in digital images. There are many different ways to perform image segmentation, including:

• Thresholding methods, such as Otsu’s method
• Clustering methods, such as K-means and principle components analysis
• Transform methods, such as watershed
• Texture methods, such as texture filters

You can perform image segmentation in MATLAB with Image Processing Toolbox, which provide image segmentation algorithms, tools, and a comprehensive environment for data analysis, visualization, and algorithm development.
