Ramesh - if the right-hand image is a binary image of 0's and 1's, then can't you get the rows and columns (y and x coordinates respectively) using the following
[rows,cols] = find(binaryImg==1);
where binaryImg is your binary image and 1 corresponds to the white pixels?

If, by chance, you want just the outline of the palm, you can use
boundaries = bwboundaries(binaryImage);
Or (not as efficiently)
[rows, columns] = find(bwperim(binaryImage));
Geoff's code can skip the unnecessary step of comparing every pixel in the entire image to 1 by simply just doing:
[rows,cols] = find(binaryImg);
