I have set of random points in 2D plane, and have to make a closed polygon without any intersection between edges. There is a possibility that one or more polygons can be drawn. How do I get all those possible polygons along with their perimeter. ...
So let's say that you wanted to generate the mask manually in MATLAB using basic tools, what tools would you use and how would the results differ? You can use the ROI tools like drawfreehand(), drawpolygon(), or drawassisted() to create editable selections for each region. You can...
Create the polygon, create a circle as large as you want, with the radius being your main variable. Pass the radius of your first circle to whatever is drawing your next circle. If you create the circle with the center being the same as the previous circle, and a smaller radius, you a...

The perimeter looks right, but to make the area right either the first point must equal the last point or you need to extend the p_area by one more term, namely, (x(n)+x(1))*(y(n)-y(1)). Also you need to either ensure that your route around the polygon is clockwise or else...
When we need to draw a rectangle on an image or plain figure in Matplotlib, the rectangle patch from matplotlib.patches should be added to the axes by add_patch method. ADVERTISEMENT A Matpotlib patch is a 2-D artist that has a face and edge color. Matplotlib has patches like, Arc Arr...

Example #5 – Implementing the Normal Distribution Curve in Histogram We shall use the data set ‘swiss’ for the data values to draw a graph. Here the function curve () is used to display the distribution line. Code: curve (dnorm(x, mean=mean(swiss$Education), sd=sd(swiss$Education))...
(2.c) is obtained. After a number of preprocessing steps consisting of background subtraction, outlier removal, denoising and/or downsampling, the primary 3D representation may be transformed into a secondary representation, such as a polygon mesh (4.a), an octree (4.b), or an undirected ...
