感謝多位前輩的幫助小弟最後的 code 附在最後丟進 data 後是給第一段和最後一段 1 的時間並有處理 part 2 和 3 的問題反而其實 part 1 不需要真的作了因為有了 bwlabel 這個 function 的關係 -- function [ roi_time_first , roi_time_last] = groitime(roi_data) roi = roi_data + 0; temp = 0; while temp == 0 [~ , num_of_roi] = bwlabel(roi); for n = 1:num_of_roi if n < num_of_roi [~, roi_time_t1] = find(bwlabel(roi)==n); [~, roi_time_t2] = find(bwlabel(roi)==n+1); time_diff = roi_time_t2(1) - roi_time_t1(end); if time_diff <= 200 roi(roi_time_t1(end)+1 : roi_time_t2(1)-1) = 1; break end else temp = 1; end end end for n = 1:num_of_roi [~, roi_time] = find(bwlabel(roi)==n); if length(roi_time) <= 100 roi(roi_time) = 0; end end [~, roi_time_first] = find(bwlabel(roi)==1); [~, roi_time_last] = find(bwlabel(roi)==num_of_roi); end -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 24.208.230.65 ※ 文章網址: https://www.ptt.cc/bbs/MATLAB/M.1441503241.A.D15.html
