Image segmentation Using MATLAB Digital Images Processing Using MATLAB What is segmentation? Image segmentation is the process of partitioning an image into a collection of connected sets of pixels. The goal of segmentation is to simplify change the representation of an image into something that is more meaningful and easier to analyses. Image segmentation is typically used to locate objects and boundaries like lines, curves in images. It is the process of assigning a label to every pixel in an image.  Three main techniques to do. Thresholding Region based segmentation Edge based segmentation Thresholding Thresholding is finding histogram of gray level intensity. Types Basic Global Thresholding Multiple Threshold Variable Thresholding Otsu’s Technique Basic Global Thresholding Primarily Segment image use: Calculate the average intensity m1 and m2 for the pixels Calculate a fresh threshold:        ...

Basic Morphological Operation Using  MATLAB Digital Image Processing using MATLAB Introduction I mage Processing is a method to perform some operations on an image, in order to get an enhanced image or to extract some useful information from it. Image Morphology is an important tool in image processing. It is the study of shapes of object present in the image and extraction of image features. Image features are necessary for object recognition. The fundamental morphological operations include Erosion and Dilation. Opening and Closing are also morphological operators. These operators are considering as basic operations in image processing algorithms. DILATION Dilation operator can be applied to binary and grey scale images. The objective of this operator is to enlarge the foreground and shrinks background. It gradually increases the boundaries of the region, while the small holes present in the image become smaller. It increases the bright...
