Nov 16, 2012 · I am having trouble achieving the correct segmentation of a grayscale image: The ground truth, i.e. what I would like the segmentation to look like, is this: I am most interested in the three components within the circle. Thus, as you can see, I would like to segment the top image into three components: two semi-circles, and a rectangle between ...
Measuring Regions in Grayscale Images - MATLAB & Simulink
www.mathworks.com › help › images
This example shows how to measure properties of objects in a grayscale image. To accomplish this, first segment the grayscale image to get a binary image of objects. Then, use the regionprops function to analyze the original grayscale pixel values corresponding to each object in the binary image.

Image Segmentation - MATLAB & Simulink
www.mathworks.com › help › images
Image segmentation is the process of partitioning an image into parts or regions. This division into parts is often based on the characteristics of the pixels in the image. For example, one way to find regions in an image is to look for abrupt discontinuities in pixel values, which typically indicate edges. These edges can define regions.
