- accumulate the events into frames and then training and testing based on these frames
- all the data into the cell (CINs) are partitioned into mupltiple frame of which consists of nEvt events
- event frequence - inverse frame frequence (ef-weight) is used to reweight the event frequence
- only SVM can be applied to this case!
- Each column corresponds to a data point.
% If the codes or data sets are helpful to you, please appropriately cite our works. Thank you very much!
The MATLAB code of BOE is stored under the filefold 'BOE', but all the other filefolds are needed!
- main_cards_DVS.m: run experiment on the card dvs data set;
- main_mnist_DVS.m: run experiment on the mnist dvs data set;
- main_posture_DVS.m: run experiment on the posture dvs data set;
To store the original DVS database
To store temporary data
The code of svm with linear kernel. If you hope to test other classifier such as nonlinear SVM, please modify the code accordingly. If you perform experiment using MAC, nothing need to be modified. otherwise, please complie the SVM lib, linearlib. We have also provided a compiled mex under the filefold ``LinearSVM_Win64โโ
