Question

下面是代码和出现的错误。请帮助我解决此问题：

代码：

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

IndexError：索引352超出了尺寸为352的轴1的边界

Answer 1

i上升到m - 1，因此i + 1上升到m，这是超出范围的。也许您应该早一点停下来？与j类似。

计数器r和g的初始化为0。在使用它们之前先对其进行递增，因此它们从1开始。您可能需要将r = r + 1行与其后的行交换，对于g = g + 1也是如此。
