Morphological Operations in Image Processing
Blog post from Roboflow
Morphological operations are fundamental techniques in image processing that focus on analyzing and modifying the shape and structure of objects within an image, primarily using binary images but applicable to grayscale as well. Rooted in the mathematical theory of morphology, these operations utilize structuring elements to probe and transform images, aiding in tasks such as noise removal, shape analysis, and feature extraction. Common operations include erosion, which shrinks object boundaries; dilation, which expands them; opening and closing, which respectively remove small objects or fill gaps; and more complex transformations like the Top-Hat transform, skeletonization, and thinning. The choice of structuring element—ranging from simple geometric shapes like squares and disks to custom designs—significantly impacts the outcome of these operations. Using the Scikit-Image Python library, these techniques can be applied to enhance image processing tasks, preparing images for more advanced applications in computer vision.
