MATLAB: Measure the surface of trapezium image measure surface image trapezium Hello, does anyone know how I can measure the surface/area of images of trapezoidal shape in matlab? Thank you Best Answer Try polyarea(). If that doesn't work for you, then explain your situation better.

MATLAB: How to select and find the colours on the areas that edge detection has separated How are you going to do that? edges aren't always closed contours. Many are just simple straight lines or curves with 2 endpoints.Maybe you'd rather use an approach like this:http://www.mathworks.com/matlabcentral/fileexchange/37197-dem--diffused-expectation-maximisation-for-image-segmentationor even the mean shift algorithm or k-means.http://www.mathworks.com/products/demos/image/color_seg_k/ipexhistology.html Related QuestionHow to calculate the area of this crescent shapeArea of many cracks in imageHow to measure surface area layer by layer using MatlabIdentifying the circle that fits the outer white pixels in a binary image (or make external mask)
