Image segmentation is the process of dividing an image into multiple segments or regions, each of which corresponds to a different object or feature in the image. Clustering methods are often used in image segmentation to group similar pixels or regions of an image together. Clustering algorithms are efficient techniques that can be used to segment images into regions of interest, where the pixels are grouped together based on their similarity in color, texture, or other features.
There are several clustering methods that can be used for image segmentation, each with its own advantages and disadvantages. Some of the most popular methods include:
K-means: A popular and widely used method that groups similar pixels together by iteratively updating the cluster centroids.
Mean shift: A non-parametric method that uses a kernel function to estimate the density of pixels in the image and groups pixels together based on their similarity in color and texture.
Hierarchical clustering: A method that groups pixels together in a hierarchical manner, starting with individual pixels and merging them together into larger clusters.
Spectral clustering: A method that uses eigenvectors of the image's similarity matrix to group similar pixels together.
Graph-based clustering: A method that uses graph-theoretic techniques to group pixels together based on their similarity in the image.
Density-based clustering: A method that groups pixels together based on their density in the image.
These methods are efficient in terms of time and space complexity, and their performance in terms of accuracy, segmentation quality and scalability. The choice of method depends on the specific requirements of the image segmentation task at hand, such as the size of the image, the number of clusters, and the desired level of accuracy.
Efficient Clustering Methods for Image Segmentation are a set of algorithms that are used to divide an image into multiple segments or regions, each of which corresponds to a different object or feature in the image. These methods are efficient in terms of time and space complexity, and their performance in terms of accuracy, segmentation quality and scalability. They are widely used in computer vision and image processing applications, such as object recognition and image analysis.
