With this vector as an input argument, we can now call the function to draw a rectangle on an already created plot. MATLAB also allows you to specify the curvature at the vertices of the rectangle, adjust the line style and width, add text, and work with different axes, which makes the...

有时候,我们处理好图像后,为了标识出图像的目标区域来,需要利用plot函数或者rectangle函数,这样标识目标后,就保存图像。一般的保存图像可以利用figure中的edit菜单中的copy figure,这样可以完成,但是保存后的图像外围多了一片区域,这是figure的区域,效果如下: 外部的白色区域不是我们想要的…… 于是我们想办法,利用imwrit...

visualization in MATLAB. Circles can represent various data points, regions of interest, or simply add aesthetic elements to your plots. MATLAB provides several methods to plot circles, and in this article, we will explore three commonly used functions for this purpose:rectangle(),plot(), and...
为1的所有地方在图像上画一个圆圈。 MATLAB中是否有任何功能可以做到这一点?我能想到的最好的是: [x_p, y_p] = find (points); [x, y] = meshgrid(1:size(im,1), 1:size(im,2)) r = 5; circles = zeros(size(im)); for k = 1:length(x_p) ...
