This tutorial will talk over how to draw lines and other shapes on an image using the plot() and insertshape() function in MATLAB.
Draw Line on an Image Using the plot() Part in MATLAB
If you desire to describe a line or other variables like the sine moving ridge on an image, you can use the plot() function to practice that. For example, let'south draw a line on an image. Come across the code beneath.
load clown prototype(X) hold on plot([180 50], [60 250],'Colour','r','LineWidth',5) Output:
In the above lawmaking, we have used an already stored clown epitome and plotted a line on the clown image using the hold on command. You can change the color of the line using the Color property and the line width using the LineWidth belongings. You can also change the starting and ending signal of the line.
Draw Line on an Image Using the insertshape() Part in MATLAB
If you want to draw shapes: line, circle, rectangle, and polygon on an image, you can apply the insertshape() part to do that. The basic syntax of the insertshape() part is given below.
Output = insertShape(Image, shape, shape_position) In the above lawmaking, Image is the image object on which yous want to depict, shape is the shape you want to depict on the image, shape_position is the position on the image at which you desire to depict the shape. For example, let's draw a circle on an image. See the lawmaking below.
X = imread('peppers.png'); output = insertShape(10,'circle',[100 100 100],'LineWidth',5); imshow(output) Output:
In the above code, we have used an already stored peppers epitome, and a circle is drawn on the paradigm using the insertshape() function. In the case of a circle, the position consists of iii values; the start value is the x-axis position, the 2nd value is the y-axis position, and the tertiary value is the radius of the circle. In the case of a rectangle, the position consists of four values, the commencement value is the x-axis position, the second value is the y-axis position, the 3rd value is the width, and the fourth value is the height of the rectangle. You can also change the color of the shape using the Color property, the line width using the LineWidth property, and likewise the opacity in instance of filled shapes using the Opacity property.
