After the operation i have to use that image for feature extraction. also with that operation quality of image remains same.
Dear Pritam Mantri,
Do you want convert to different color spaces?
Do you want convert to different sizes?
Do you want use MATLAB?
Question is not clear, if you simply want to resize a grayscale image of size 64x64 pixels into 36x36 pixels in Matlab you can use imresize function.
A=imread('path of the image');
X=imresize(A, 0.5);
in X you will get the resized image.
the question is not clear. do you want to get entire image into 64*64 or to get some portion of the image. It is very easy as Mr. Manikandan said.
You can use imresize function for resizing the required image in MATLAB
As pointed out by other researchers, the question asked is not clear.
Read the original image of size 206 x 205 into some variable (say I). Further, resize it the image size of which you are interested.
I = imread('test.tif'); % test.tif is an example image
I_resize = imresize(I, [64 64]);
You better to read some topics on this regard. Pls go through http://in.mathworks.com/help/images/ref/imresize.html
