SelectiveSearchCodeIJCV遇到First two input arguments should have the same 2D dimension

在windows 10+visual studio环境下运行SelectiveSearchCodeIJCV中的demo.m难免会出现下列错误

-----------------------

if(~exist('mexFelzenSegmentIndex','var'))

-----------------------

错误使用 CountVisualWordsIndex (line 21)
First two input arguments should have the same 2D dimension

出错 BlobStructColourHist

出错 Image2HierarchicalGrouping (line 42)
[colourHist blobSizes] = BlobStructColourHist(blobIndIm, colourIm);

出错 demo (line 61)
[boxes blobIndIm blobBoxes hierarchy] = Image2HierarchicalGrouping(im, sigma, k, minSize, colorType,

simFunctionHandles);

原因是：Dependencies/FelzenSegment/mexFelzenSegmentIndex.cpp

行149：int* dims = (int*) mxGetDimensions(input[0]);

中int的问题。

方法一：

把demo.m中mex  Dependencies/FelzenSegment/mexFelzenSegmentIndex.cpp -output mexFelzenSegmentIndex;

改为

mex -compatibleArrayDims Dependencies/FelzenSegment/mexFelzenSegmentIndex.cpp -output mexFelzenSegmentIndex;

因为在 mex -compatibleArrayDims下mwSize才等于C中的int。

方法二：

直接将

int* dims = (int*) mxGetDimensions(input[0]);

改为跨平台使用的数据类型mwSize

mwSize* dims = (mwSize*) mxGetDimensions(input[0]);
