How can use [c r p]=impixel('img1.png'); turn to an knowing [c r] to impixel image

firstimage=imread('img1.png');
[c r p]=impixel(firstimage);

There is my question:

I can use the code above so for the first image I can get a value to impixel,

and now I want to use the same range,to do to the other,different case but same place,

so what I think is to get the first image [c r] value so I can write like this

 impixel(firstimage c r)

so I can get the some range about it

but I have no idea how to get c value,because c is a double(matrix.....I think)

please help me about it,thanks

Hi Huang,

firstimage=imread('img1.png'); %Line 1
[c r p]=impixel(firstimage); %Line 2

It is my understanding that you want to get the c and r values of firstimage and apply impixel on other image (or firstimage) for same (x, y) coordinates i.e., c and r values.

secondimage = impixel(other_image,c,r); %Line 3

In line 2, you will get numeric vectors c and r that can be used as (x,y) coordinates in other image. So, line 3 will return pixel values for the other image for same (x, y) coordinates as used in firstimage.
