比较图像的两个坐标值 [英] Compare two coordinate values of an image

问题描述

我有一组坐标值，我想将这些值相互比较.我想要x-min，x-max，y-min，y-max作为结果. 例如 : (10,40) 和 (20,30) 是两组值. 我想比较一下； 它应该是结果:

i have set of co-ordinate values and i want to compare these values with each other. I want x-min, x-max,y-min ,y-max as result. For example : (10,40) and (20,30) are two set of values. i want to compare them; it should be the result:

x-min=10
y-min=30
x-max=20
y-max=40

推荐答案

如果x和y具有单独的数组，请参见@Andrey的答案. 如果您有一个类似

If you have separate arrays for x and y, see @Andrey's answer. If you have an array like

A = [x y] = [
    10 40
    20 30
    ..
    90 25];

然后使用此:

mins = min(A);
maxs = max(A); 

minX = mins(1);   maxX = maxs(1);
minY = mins(2);   maxY = maxs(2);
