First, we convert the image to grayscale and use a morphological top-hat operator (one of many new grayscale morphological tools) with a disk-shaped structuring element to smooth out the uneven illumination. Image segmentation techniques are basically ad hoc. Introduction to Image Segmentation The purpose of image segmentation is to partition an image into meaningful regions with respect to a particular application The segmentation is based on measurements taken from the image and might be grey level, colour, … Image Segmentation Definition: Partitioning a picture/image into distinctive subsets is called segmentation. Thus, the idea is to create a map of full-detected object areas in the image. ), satellite image interpretation (buildings, roads, forests, crops), and more.. The Watershed transformation is a powerful tool for image segmentation, it uses the region-based approach and searches for pixel and region similarities.
