What is the difference between graylevel image and intensity normalized image?
I have gray level images and I'd like to normalize them by intensity before next stage process. These gray level images are converted from RGB images by rgb2gray(). The pixel value varies between 0 and 255.
Here is what I do (follow ImageAnalyst's code)
image = imread('grayImage.bmp');
imageMin = double(min(min(image)));
imageMax = double(max(max(image)));
imageRange = imageMax - imageMin;
newMin = 0;
newMax = 1;
newRange = newMax - newMin;
newImage = newRange * (double(image) - imageMin) / imageRange + newMin;
imwrite(im, 'newImage.bm...Normalizing an image
I have an RGB image and i want to use the LST color space (similar to the Ohta color space).
L = (k/sqrt(3)) * (R+G+B)
S = (k/sqrt(2)) * (R-B)
T = (k/sqrt(6)) * (R-2G+B)
Then I have to compute a histogram for each channel with 16bins. The problem is that i have to normalize de image so i can use this to compose a color feature, but i don't know how normalize the image.
Can anyone help me?
Just divide by 65535 to get them into the range of 0-1.

My job is to classify raptors into their specific type using Artificial Neural Network.
I have already finished processing the image and now i have the raptor's silhouette. The thing is, not all raptor faced the same direction in the image, therefore i need to find a way to normalize them so that they would be looking the same direction (consistent). I also have problem finding useful features to look into for my NN inputs.
About normalizing the raptor, i thought about using a rectangle to compare every angle of the silhouette till the rectangle fill most of the image (wings of an raptor ...normalizing binary image

How about finding the bounding box, then using imcrop or indexing to
crop the image, then using imresize to make it the size you want?

Do not expect us to do the searching for you, or do all of your work
for you. Do your own homework. If you get stuck after doing most of
the work, we will likely help you.

How about dividing by the max value?

that normalizing may be a good thing for you to do when you...
