Module 2.1: Boundary Extraction| Image Morphological Operation | Digital Image Processing #subscribe
Hello Students, Internal and external boundary extraction are fundamental operations in digital image morphology that help in understanding the shape and structure of objects within images. Internal Boundary Extraction Internal boundary extraction refers to the process of identifying the boundaries of an object within an image that separates it from its background. This is typically achieved by using morphological operations such as erosion. In this context, the inner boundary is calculated by subtracting an eroded version of the original image from the original itself, mathematically expressed as: Inner Boundary=Original Image−Eroded Image The eroded image is obtained by applying a structuring element to shrink the original image, which effectively removes outer pixels and highlights the internal shape of the object. This operation is particularly useful for analyzing the size, shape, and position of objects within an image. External Boundary Extraction External boundary extraction, on the other hand, focuses on identifying the outermost boundaries of an object or a specific region within an image. This is accomplished through dilation operations, where the dilated image is created by expanding the original image using a structuring element. The outer boundary can be defined as the difference between the dilated image and the original image, expressed as: Outer Boundary=Dilated Image−Original Image This method allows for the extraction of outlines of all objects present in the image. External boundaries are particularly valuable for tasks like image cropping and background removal, as they define the edges of regions or objects effectively. Together, both internal and external boundary extraction play essential roles in image processing, helping to formulate accurate representations of image features for further analysis.
