I guess you'll be using rgb2hsv() to do that, unless you want accurate
results instead of the book formula.  In that case you'll have to
calibrate your system by imaging a known standard, such as the xrite
ColorChecker Rendition Chart.  It can be quite tricky and involved to
do calibrated color imaging if you really need the utmost accuracy
(involves measuring the OECF of the camera/scanner, using a
spectrophotometer, etc.), so I'm not going to get into it.

I know there is the function which converses an image from RGB to HSV color space is rgb2hsv. But is there any function which convert only one value RGB to HSV? Thang Nguyen.

RGB transform
Hi all , I want to extact the 3 components R,G,B of an image and convert them in a space of two dimension trough two formulas like as : a=f(R,G,B) b=g(R,G,B) Where f and g are two simple rational functions .

Most graphics APIs seem to want colours specified in RGB space. But RGB is a poor choice for doing colour manipulations; for example, if you want a lighter or darker version of a given colour, naive manipulations directly on the RGB components are likely to lead to hue shifts. A better space to work in is HSV. This way, you can, say, tweak the saturation or brightness, and leave the hue unchanged. It is also easier to predict what colour you are likely to get from a given set of HSV values. Even if your graphics API doesn’t support it directly, you can still convert to HSV, do your man...

transformation between xyY and RGB
Dear all, I have some questions about the use of icc Matlab commands of Image Processing Toolbox. I need to convert xyY coordinates to RGB coordinates. How can I specify the Y (in cd/m2 or normalized between 0 and 1)? I obtained incorrect results, so I tried the invers process: transformation from RGB to xyY but I find Y always smaller than one. Is it normalized? If yes, how can obtain Y in cd/m2? and what's the value I have to moltiply for the de-normalization? Any help will be appreciated!! Many thanks in advance!

Hi, I had to build a function that converts RGB to HSV. This is what I've done so far but I am not sure if it is correct or not. Plus, I am stuck with Hue conversion.. can someone help me to verify if I am on the right track or at least give a hint. I've tried to verify it using the built in function rgb2hsv in matlab, but when I plot it separately, there was only a blue image appeared. To verify it, this i did H=rgb2hsv(I); image(H(:,:,1)); image(H(:,:,2)) etc2.. % --------------------------------------------------------------------------------------------------------- % This funct...

Image processing RGB to HSV
Hi ! I faced some problems in converting the RGB images in database to RSV. I have to convert all the images in the database to HSV and extract the feature vectors. I don't know how to convert all the images in the database to HSV. Can anyone help me? here is my code for RGB images 2D histogram: count=0; distance=0; for i=1:90 % first 90 images in database (which are categorized as beach) for j=91:810 % other images in database h1 = database{i}.Hist; h2 = database{j}.Hist; count = count+1; distances(count) = sqrt(sum(sum((h1-h2).^2))); % get euclidian di...
