Hi, For example, I have a 500*500 size of image, but I normalized the range of [0 1], then how to find the image actual coordinate value from the normalized image value
Dear Adhiyaman Manickam,
If I understand your question correctly, this will be the answer;
You have always the index of matrices, you can find the value of an index of one element and use find function to find the value or index of the corresponding metric in the normalized matrix and vide vera.

Assuming that the upper left hand corner is the origin (0.0, 0.0), and that the x and y pixel-indices start at 0, then the coordinate of pixel (i, j) is:
PixelSizeX = 1.0 / (500 - 1);
PixelSizeY = 1.0 / (500 - 1);
CoordXY = (i * PixelSizeX , j * PixelSizeY);
Normalization will not change in the coordinates of pixels in the image. Instead normalization will change their values.
Example:
Suppose "Img1" is your image.
Suppose that "Img2" is obtained by normalizing "Img1".
Pixels in "Img2" will always have the same coordinates as in "Img1".
You have to clarify your question or tell us the exact problem you are facing in order to provide you with more help.
