Hello. I'm a beginner at Matlab.
I want to use for loop.
I got data (25 x 12852) using this code.
I want to concatenate the matrix (dist).
For example, the last part of whole code,
dist = dtw(data(:,1),data(:,2));dist = dtw(data(:,2),data(:,3));dist = dtw(data(:,3),data(:,4));dist = dtw(data(:,4),data(:,5));dist = dtw(data(:,5),data(:,6));......dist = dtw(data(:,12851),data(:,12852));
Finally, I want to get one matrix.
Can I get an idea to solve this?
Also, is it resonalble to use dynamic time warping (DTW) for video classification?
clear allclose all%// read the video:
list = dir('*.avi')% loop through the filenames in the list
for k = 1:length(list) reader = VideoReader(list(k).name); vid = {}; while hasFrame(reader) vid{end+1} = readFrame(reader); end %// estimate foreground as deviation from estimated background:
cellSize = [8 8]; for i=1:25 fIdx(i) = i; %// do it for frame 1 ~ 60
frameGray{i} = vid{fIdx(i)}; [featureVector{i},hogVisualization{i}] = extractHOGFeatures(frameGray{i},'CellSize',cellSize); end data = cell2mat(featureVector'); data = double(data); dist = dtw(data(:,5),data(:,6));end
