我正在使用 CGAL 计算两个凸多边形相交的面积。在对 this 的接受答案中发布了执行此操作的简短演示代码...
mask = poly2mask(x2, y2, ceil(max(y2)), ceil(max(x2))); % Display the image. p2 = subplot(2, 2, 2); imshow(mask); axis(p2, 'on', 'xy'); title('Mask Image', 'FontSize', fontSize); % Compute the Euclidean Distance Transform edtIma...
. I first thresholded the image, then eroded the mask to get a roughly square shape, filled in the holes, then dilated the mask using a square shape that touched all 4 sides.Thank
ordered cw or ccw - it's basically random. They are also not concave, and so I can't use (or I can't figure out) the polygon functions (polyshape, boundary, alphaShape, convhull, etc) as they do not draw the boundaries correctly, and hence can't use ...
在《使用 MATLAB 对 FLUENT 的计算结果进行后处理——非结构化网格上的等高线图、云图与矢量图》一文中作者举例说明了用单幅图表现 FLUENT 计算结果的方法。但是有时候,单幅图不足以表达意图,需要将多幅图拼在一起使用。这篇文章即说明这种拼图的绘制方法。

Sometimes, it seems there is a problem on how the function wants 2D inputs and sometimes 3D inputs. Here's a sample. How can it take the first vertex and not the second one? Copy pgon = polyshape([1 1 2 4], [1 4 4 1]); ...
(mask)>1 mask = strcmpi(pname,pnames); % use exact match to resolve ambiguity if sum(mask)~=1 m = message('stats:internal:parseArgs:AmbiguousParamName',pname); throwAsCaller(MException(m.Identifier, '%s', getString(m))); end end varargout{mask} = varargin{j+1}; setflag(mask) ...
