07 Dec 2014 Linear Kalman Filter A fully commented script which explains Linear Kalman Filtering in the form of a simple example. Author: Amir Omidvarnia Yossarian

yh_(:,i) = C * xh_(:,i) + R;

Line 79 maybe wrong, because the estimated observation y(t|t-1) = C*x(t|t-1). It should be just like line 69, xh_(:,i) = A * xh(:,i).

Hello, this code does not give right results if the training database contains the image that we choose for testing. If the image chosen for testing is a face that already exists in training database but a different image of the face, it's not giving the correct results, anyone having same problem?

Hi
i wanted to ask is there any pre-processing can be apply to the recognition to improve recognition rate?

Hello, can u suggest how can I change dimension of all my 320x240 images to 200x180 images? It is urgent for me.

@SUMAN AND RAMYA

i also got the same error..the solution is this will work for same dimension images..i changed all my images in the data base with same dimension eg(200*180);
then i got the output..try it best wises

for the problem encountered in using "quadtfd",I read the handbook of TFSA 5.5, find that "To install the distribution on MS-Windows simply run the tfsa 5.5 win.exe file." ,but this file is not included in its winzip file from (http://espace.library.uq.edu.au/view/uq:211321).

Hi,Omidvarnia,thanks for sharing.

a problem encountered when trying the simulated data:

Attempt to execute SCRIPT quadtfd as a function: D:\Codes\tfsa_5-5\windows\win64_bin

Error in ==> GPS_SingleSegment at 49
tfd = quadtfd( sig', lag_window_length, time_res, 'mb',.01);

By the way,I am using Windows. Thanks

CAT arguments dimensions are not consistent.

Error in ==> CreateDatabase at 47

great work..in your code it is not show eigenvalue ..it is just recognize face with train image.can you tell me how to show eigenvalue?

first of all Thanks a heap.How can I average results for more than one data set (need PDC results for 6 patient's EEG data).Do i need to average 4-D matrix PDC_ST and then surrogate and ploting ?? please help!

@Jaime
Thanks to you for your correctness in this cod in fisherfacecore.m file
its really effective for me.

Thanks and best regards.

great work!! i have created my own traindatabase , but if i eliminate test database and try to take the test image via webcam and store it directly into a matlab variable and then run the program , it is not recognising my image but rather match some other face in the traindatabase.. i have resized test image appropriately and no errors are found when i run the code.. just face recognition fails... please suggest if i need to make any changes in the code or any other measures need to be taken into account while image capture through webcam like lighting. or any specific background needed.. please reply and help me ..

great work indeed!!very neatly computed!...I will be very happy if you can suggest how we can reject non-face images by calculating the Euclidean distance of the mean/centered test image from the face space??(Re:"Pentland and Turk:Eigenfaces for Recognition)

09 Jun 2012 PCA-based Face Recognition System This package implements 'Eigenface', a PCA-based face recognition system. Author: Amir Omidvarnia Shamir Alavi

I've run the code several times using my own face database and it seems its trying to recognize on the basis of same file names in both training and test folders !!! I changed the file names several times to check this theory and as suspected, the recognition came out to be wrong. Only once it truly recognized the same face having different file names. Most of the times, it was just matching both 1.jpg files regardless of whose picture i put there.

Hello,

I noticed that you don't sort the eigenvectors at all. All you did was keeping the eigenvalues that are greater than 1 and their associated eigenvectors.
Can you tell me why please.

Can the author or anyone tell me why the Eigenfaces is 36000*19 instead of 36000*20? Why the D[1 1] would be negative value that causes the dimemsion to be 19?

Tsai, I forgot to mention that Sb should be multiplied by the number of pcitures per class (in this case 2), you are right on that too. Refer to section 2.4 of the following paper to note the error: http://www.face-rec.org/algorithms/LDA/belhumeur96eigenfaces.pdf

If you guys would like to look at another sample Matlab code for fisher faces, look at:

12 Dec 2011 FLD-based Face Recognition System This package implements 'Fisherface', a FLD-based face recognition system. Author: Amir Omidvarnia Jaime

Tsai there is a mistake indeed; the order of the eigenvectors is backwars, and you are using the eigenvectors with less relevance.

In line 43 of FisherfaceCore.m, you have to substitute line 43:

"for i = 1 : P-Class_number"

for

"for i = P:-1:Class_number+1"

This will solve the problem. I tested with all the faces in the sample set, and it was 90% accurate.

Everything has been working perfectly, thanks for an excellent and well commented code Amir!
