what kind of data you have.
there are lots of features Morphological and discrete such as mean, Variance, RR interval etc.
once you have data vector then you can proceed for features
well you have to first binarize the image first and you can do that by proper thresholding . Once you got the image free of unwanted info you can play with that image using matlab or what ever that suits.
I have 100 ECG samples from 05 ECG classes. (20s/class)
I determined 7 features after preprocessing and segmentation of ECG data.
Then used Dimensionality reduction techniques PCA,LDA and reduced the feature space to 2 from 7.
Finally Minimum Distance Classifiers used for classification.
Now i...
I have tried this code below for plotting ecg from physionet as given by echo47 during my last conversations
that time it worked but now when i am get back to it it is not working
i have downloaded the rdsamp.exe file,wfdb-10.4.dll file and the libcurl-3.dll and downloaded the .atr, .dat and...
I am working on ECG patterns. my feature matrix is 50X18. 50 samples and 18 features per sample. i applied PCA but this effort did not give me good results. i want to apply LDA also known as FDA. Can anybody help?
t wave detection
I need help in detection of P, QRS, T, R wave detection. i want to follow Derivative based and Length Transform Method. Can any body share experiences with me.

Dear Friend u can see my code on the top in this conversation . Mr. Nick gave me a solution , i am not able to incorporate that into my code. i request for help me incorporate this code into my code. i am not understanding how i can convert my vector into a 3 dimensional array as said by Mr...
Dear Nick
i am not getting this code and am stuck plz insert this code into my code so that i can get it or plz guide me some other way about this part of code... plus i dont get this 3 dimension array concept.

matlab using graythresh
Here is a matlab code i am using for ecg image analysis. actually i am capturing an image named s2.png in 1D;
i have 10 images like s1,s2,,,,,,,,,s10,.............or more
if i wanna read all of them at once not one by one and then find the program processed output plot...
segmentation matlab code
its nice ,, i am greatful but there iz one problem i want to incorporate a loop as u can see below:
d1 is my vector
i want to get seg1, seg 2,,,,,,,,,,, by doing as below,,, but it is working as below but not as ""seg(jk)""
because segjk gives the last segment of my...
