Question

我在我的linux系统中安装了MATLAB2015a。在安装MATLAB时，我已经在我的系统中安装了几乎所有的软件包。运行以下代码时，我遇到了一个严重的错误。任何人都可以帮助我：我需要工具箱：

Commands:

I = checkerboard;
corners = detectHarrisFeatures(I);
imshow(I); hold on;
plot(corners.selectStrongest(50));

错误： 未定义函数'detectHarrisFeatures'用于'double'类型的输入参数。

Answer 1

我认为您需要使用灰度来使用detectHarrisFeatures函数。所以正确的代码是：

I = checkerboard;
I_grayscale = rgb2gray(I);
corners = detectHarrisFeatures(I_grayscale);
imshow(I); hold on;
plot(corners.selectStrongest(50));

MATLAB：未定义函数'detectHarrisFeatures'用于'double'类型的输入参数
