运行用于虹膜识别的 libor masek 代码时出错

Question

当我为 Iris Recognition 运行 libor masek 代码时，我正在调用 segmentiris 函数，我收到错误消息

??? Undefined function or method 'conv2' for input arguments of type 'double' and   attributes 'full 3d
real'.

Error in ==> filter2 at 73
    y = conv2(hcol, hrow, x, shape);

Error in ==> canny at 40
im = filter2(gaussian,im);        % Smoothed image.

Error in ==> findcircle at 43
[I2 or] = canny(image, sigma, scaling, vert, horz);

Error in ==> segmentiris at 49
[row, col, r] = findcircle(eyeimage, lirisradius, uirisradius, scaling, 2, 0.20, 0.19, 1.00, 0.00);    

Answer 1

在 2D 中分别过滤每种颜色 (RGB)：

filter_g = zeros(size(im_double));

for i = 1:3
  filter_g(:,:,i) = conv2(gauss, im_double(:,:,i);
end

或者你可以使用convn()
