sorry, your report link can't open and be downloaded, can you give me a new link or the article's name which I can search? thank you very much.
FYI, I did not find where the SPM is used.

Do you recall the dictionary size (number of clusters in Kmeans to generate the "codewords") you used to generate the voc.pkl? I tried 200, and my accuracies are much worse than yours:
Yours:
Level 2, 21 * (vocabulary size) dimensions, in this case, 6300 dimensions for each histogram
SVM (linear): 0.875 (105/120)
SVM (poly): 0.316666666667 (38/120)
SVM (rbf): 0.741666666667 (89/120)
SVM (sigmoid): 0.166666666667 (20/120)
SVM (Histogram Intersection): 0.85 (102/120)
KNN: 0.483333333333 (58/120)
Mine (with vocabulary size 200):

Hi,
I am trying to build vocabulary for my own data set. I am not sure what to give into 'stackOfDescriptors' to the visualVocabulary class.
Any help?
