Multitude Regional Texture Extraction for Image Lecture 18 Segmentation Region Based

Region Growing is an approach to image segmentation in which neighboring pixels are examined and added to a region class if no edges are detected This process is iterated for each boundary pixel in the regionMultiple regions can also be identifi ed by scanning the image in a regular fashion adding pixels to growing regions and spawning new regions as needed We can then make additional passes through the image resolving these regions

classify the pixels of an image correctly in a decision oriented application Therefore we can state that the objective of image segmentation is to simplify or change the representation of an image or convert the information of an image into a more meaningful form so that it make it easier for further analysis It divides an image into a number of specific regions such that the pixels The region merging after the region growing also suppresses the high frequency artifacts The updated merged regions produce the output in formed of segmented image This algorithm produces the results that are less sensitive to the pixel location and it also allows a segmentation of the accurate homogeneous regions

A seeded region growing algorithm is then used to segment the image based on the color edge information and the distances between edge pixels and non edge pixels Seed regions are created automatically These regions grow simultaneously After all pixels in the image are labeled the boundaries shared by two regions are checked If a boundary is weak enough it is eliminated and the classify the pixels of an image correctly in a decision oriented application Therefore we can state that the objective of image segmentation is to simplify or change the representation of an image or convert the information of an image into a more meaningful form so that it make it easier for further analysis It divides an image into a number of specific regions such that the pixels
