MATLAB: Find the intersecting points curve fittingimage analysis How can I calculate the intersecting points (red circled) from the following image? Best Answer If you have the image in hand. Get the locations/ positions i.e (x,y) for both the regions using logical indexing. Get the boundary of both the regions using boundary. Use InterX from the link: https://in.mathworks.com/matlabcentral/fileexchange/22441-curve-intersections?focused=5165138&tab=functionIf you have points (x,y) straight away follow from step 2 in the above. Related SolutionsMATLAB: Area of intersection of two ellipses You can follow the below steps. For the two ellipses i.e get coordinates of both the ellipses. Let L1, L2 be your coordinates of both the ellipses. Use this function interx to get the the intersection points. This will give you four points. https://in.mathworks.com/matlabcentral/fileexchange/22441-curve-intersections?focused=5165138&tab=functionUse this function to fit the ellipse. https://in.mathworks.com/matlabcentral/fileexchange/3215-fit_ellipse MATLAB: Intersecting image with plane So you want to compute a level curve? Why would you not just use a contour plot to do that? If you want the curve itself as a polygonal path in the (x,y) plane, then:help contourc Related QuestionMake polar coordinate from cartesian coordinateHow to check if two vectors of different length intersectHow to find the point where most lines intersect in a binary image
