Normalized image

I want to calculate the boundary of the signature image before going to Moment Invariant, the algorithm should check from left to the right the first white pixel is the left boundary and the last white pixel is the right boundary. Similarly from top to the bottom.

My research step:

  1. Data Acquisition
  2. Preprocessing
  3. Signature Boundary Calculation
  4. Moment invariant
  5. fkcn

This is my code so far 

a=imread('ttd.bmp');  
b=rgb2gray(a);  
c=im2bw(b);  
c=~c;  
c=1-c;  
c=(c == 0);  
imshow(c);

Normalize? You mean map it to range [0,1] ? img is your single channel input image you want to map:

imgNormalized = (img-min(min(img)))./(max(max(img))-min(min(img)))
