You are not using the function correctly. your code is this (verbatim): f = figure; hax = axes(f); af = figure(‘Name’, ‘Do Not Touch’); x = rand(1,100); y = rand(1,100); linewidth=1; plot(hax, x,y, ‘LineWidth’, linewidth); I = getframe(hax); I = I.cdata; The matrix I is not a matrix that contain peaks like the function is … Read more

According to your new rules, may be this helps: data1 <- data #changing some elements to test the code data1[2,8] <-2 data1[4,1] <- 1 ##The code is for the row indx <- which(t(sapply(split(data1 == pattern, row(data1)), { function(x) colSums(sapply(1:(length(x) – 3), function(i) x[seq(i, i + 3)]), na.rm = TRUE) == 4 })), arr.ind = TRUE) … Read more
You could try a library like the Oddcast Face Detection API, which tracks points like the eyes, the nose and the chin. http://www.oddcast.com/dev/facedetectionAPI/ You need to buy a license for this API. There are a couple of other libraries for face detection with Flash, but this is the only one so far that tracks different … Read more
There are a couple of simple basic ideas you can put to work here. First, take the input audio and divide into small sized buckets (on the order of 10’s on milliseconds). For each bucket compute the power of the samples in it by summing the squares of each sample value. For example say you … Read more
