Question

我在matlab中执行以下代码。

ver
img = imread('/usr/local/MATLAB/coursera_svm/10.pgm');
[featureVector, hogVisualization] =extractHOGFeatures(img);

输出：

未定义的功能＆＃39; extractHOGFeatures＆＃39;对于输入参数类型＆＃39; uint8＆＃39;。

有人可以帮我解决这个问题。感谢。

Answer 1

extractHOGFeatures是计算机视觉系统工具箱的一部分，您似乎已安装...如果您这样做，您会看到什么

>> which extractHOGFeatures

如果它告诉您找不到extractHOGFeatures，请执行以下操作：

>> rehash toolboxcache

再试一次。如果这不起作用，则计算机视觉系统工具箱的许可证可能存在问题。您可能需要与系统管理员联系，或致电Mathworks技术支持。

请参阅rehash toolboxcache的文档。

图像处理工具箱已经安装了未定义的功能＆＃39; extractHOGFeatures＆＃39;对于类型＆＃39; uint8＆＃39;的输入参数
