    <p>I am working on a project which is about pattern (male/female)classification with matlab.I have a problem, I need your help, please.</p> <p>My program should find mean images of datasets. First dataset is women,second dataset is men. So first mean image has to look like a woman and second a man.I have different datasets which all have format of jpeg. I am trying different datasets for my program to check if it is working but when I use different datasets I can not see true mean images all the time, for ex:</p> <p>They are mean images from a dataset:</p> <p><img src="https://i.stack.imgur.com/qo2KZ.jpg" alt="enter image description here"></p> <p>But when I use another dataset my mean images are like this, they have no meanings, I mean they dont look like face:</p> <p><img src="https://i.stack.imgur.com/FdCj8.jpg" alt="enter image description here"></p> <p>What can be the reason for this? I should work with different datasets. Please help. `</p> <pre><code>filenamesA = dir(fullfile(pathfora, '*.jpg')); Train_NumberA = numel(filenamesA); %%%%%%%%%%%%%%%%%%%% Finding Image Vectors for A imagesA= []; for k = 1 : Train_NumberA str = int2str(k); str= strcat(str); str = strcat('\',str,'b','.jpg'); str = strcat(pathfora,str); imgA = imread(str); imgA = rgb2gray(imgA); [irowA icolA] = size(imgA); tempA = reshape(imgA',irowA*icolA,1); % Reshaping 2D images into 1D image vectors imagesA = [imagesA tempA]; % 'imagesA' grows after each turn imagesA=double(imagesA); end` `%%%%%%%%%%%%%%%%%%%%%%%% Calculate the MEAN IMAGE VECTOR for A mean_vectorA= mean(imagesA,2); % Computing the average vector m = (1/P)*sum(Tj's) (j = 1 : P) mean_imageA= reshape(mean_vectorA,irowA,icolA); % Average matrix of training set A meanimgA=mat2gray(mean_imageA); figure(1); imshow(rot90(meanimgA,3));` -------------------------------------And same for dataset B (male) </code></pre>

    1. COIt's impossible to say, because you haven't shown any code.

    3. COOk, you should do some debugging yourself first. For a start, you need to simplify your code (all the stuff to do with creating a filename is irrelevant, for instance). You should then inspect intermediate variables, to make sure they're what you expect.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
