IndexError: index 352 is out of bounds for axis 1 with size 352

Below is the code and the error I'm getting. Please help me to fix this:

Code:

def cross_number(enhanced_img, m, n):
# minutiae extraction using crossing number method

    r=0
    g=0
    row_start = 3
    col_start = 3
    mep = np.zeros((m,2))  # array for indices of minutiae points (end point)
    mbp = np.zeros((m,2))  # bifurcation point

    for i in range(row_start, m):
        for j in range(col_start, n):
            if enhanced_img[i,j] == 1:
                cn = (1/2)*(abs(enhanced_img[i,j+1] - enhanced_img[i-1,j+1]) + abs(enhanced_img[i-1,j+1] - enhanced_img[i-1,j]) + abs(enhanced_img[i-1,j] - enhanced_img[i-1,j-1]) + abs(enhanced_img[i-1,j-1] - enhanced_img[i,j-1])+ abs(enhanced_img[i,j-1] - enhanced_img[i+1,j-1]) + abs(enhanced_img[i+1,j-1] - enhanced_img[i+1,j])+ abs(enhanced_img[i+1,j] - enhanced_img[i+1,j+1]) + abs(enhanced_img[i+1,j+1] - enhanced_img[i,j+1]))
                if cn == 1:
                    r = r+1
                    mep[r,:] = [i,j]
                elif cn == 3:
                    g = g+1
                    mbp[g,:] = [i,j]

    return mep, mbp

Error:

IndexError Traceback (most recent call last) in () ----> 1 end_point, bifur_point = cross_number(dedot_image, row, col)

in cross_number(enhanced_img, m, n) 294 for j in range(col_start, n): 295 if enhanced_img[i,j] == 1: --> 296 cn = (1/2)*(abs(enhanced_img[i,j+1] - enhanced_img[i-1,j+1]) + abs(enhanced_img[i-1,j+1] - enhanced_img[i-1,j]) + abs(enhanced_img[i-1,j] - enhanced_img[i-1,j-1]) + abs(enhanced_img[i-1,j-1] - enhanced_img[i,j-1])+ abs(enhanced_img[i,j-1] - enhanced_img[i+1,j-1]) + abs(enhanced_img[i+1,j-1] - enhanced_img[i+1,j])+ abs(enhanced_img[i+1,j] - enhanced_img[i+1,j+1]) + abs(enhanced_img[i+1,j+1] - enhanced_img[i,j+1])) 297 if cn == 1: 298 r = r+1

i goes up to m - 1, so i + 1 goes up to m which is out of bounds. Maybe you should stop one earlier? Similar for j.

The counters r and g are initialized 0. You're incrementing them before using them, so they end up starting from 1. You probably need to swap the r = r + 1 line with the one after it, and similar for g = g + 1.
