Here's a suggestion:
http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer
Read that, then explain better what you mean. Otherwise all I can suggest to to look at things like dlmread(), fread(), and similar kinds of text reading functions.

Please, Vivek, post any details. There is absolutely no chance, that we can guess how the "pixel values" are stored in the file.

An image in MATLAB is an array (matrix) of pixel values. I'd say you have 2 steps. 1. Importing the TXT file. 2. Display the image. For 1. there are tons of options. Read the doc, try IMPORTDATA and other commands and if you need help, ask here. For 2. the commands are IMAGE or IMVIEW.

Hi,
I am using this command for finding mean of the 10 images
mean(cat(3,IMG1,IMG2,IMG3,IMG4,IMG5,IMG6,IMG7,IMG8,IMG9,IMG10),3)
Here 3 is the dimension
Why to use 3 dimension here?
When I am using 2 dimensional I am not getting the answer.why?

Just answered this in your other topic. Duplicating questions makes for more work :(
