Unsigned 16-Bit Image Brightness Contrast

Hello, Everyone
I have Unsigned 16-Bit Image , I want to change the brightness & Contrast of this Image.
I dont found any VI in LabVIEW to do that with this format (there is BCG but only for 8-Bit).
I found this link for that issue:Adjusting Brightness and Contrast for 16-Bit Image
So, I used the Operators function to do that. but i dont know if the order of that functions is sensitive or NOT. see Picture
and did i realy need to use Subtract operators and Divide operators .
Best wishes

Hi Al-Zahrani,
I don't believe that it matters whether you do brightness or contrast first. You can verify this by looking at a picture using both methods you showed below. However, when I did this, I did not see much of a difference and believe that you can place either brightness or contrast first. Also, you will need to include the math functions in order to perform the image processing you are trying to do. Hope this helps!

BCG Brightness Contrast Gamma - Looking for BCG function returning color table / lookup table coded in pure G and applicable to Intensity Graph or Picture Control

Looking for BCG function returning color table / lookup table coded in
pure G and applicable to 8-bit Intensity Graph or Picture Control. Do
not want to use IMAQ Vision is this particular application. Any
help is appreciated.
Sincerely,
Don

Take a look at this color model software I put together. (Don't concern yourself much with the basic programming at this point.). The color component generator subVI is borrowed from a LabVIEW example.
First look at test_color2.vi. If you adjust the sliders of the various controls, you will see how it works. You can see that for pure B&W images, brightness, contrast, and gamma (which I think I have coded correctly) are all fairly straightforward to modify.
Now look at test_color3.vi. Here we try to adjust BCG for color images using the color model shown here where current color component clusters are carried into the BCG event cases via shift registers. You can see that once color is introduced into the image, it becomes difficult to mix the colorizing with the BCG model. And this is pretty much where I am right now.
Would be interested in comments / suggestions.
Sincerely,
Don

How to Change Brightness, Contrast and Saturation of an image in LabWindows/CVI (Urgent) ?

Hi All
I want to change brightness, contrast and saturation of an image, plz help me how it will possibe in labwindows/cvi
Thanks

CVI does not include native functions to operate such changements on an image.
It may be possible that these functions are included in IMAQ library, but I never used ot so I'm not sure. In any case, this is an additional tool to install and it is not free.
Alternatively, you may need to search for a third party library that offers such functions.
Proud to use LW/CVI from 3.1 on.

Brightness/Contrast of an indexed image

Hi all,
Is it possible to change the Brightness/Contrast of an indexed image?
I've tried that with the following code:
// Brighten the image by 30%
float scaleFactor = 1.3f;
RescaleOp op = new RescaleOp(scaleFactor, 0, null);
bufferedIm = op.filter(bufferedIm, null);but it outputs:
java.lang.IllegalArgumentException: Rescaling cannot be performed on an indexed imageThanks in advance

Just roll your own: get the color components of the IndexColorModel, rescale them, build a new
IndexColorModel from that and put that together with the original WriteableRaster to form the
rescaled BufferedImage:
import java.awt.*;
import java.awt.image.*;
import java.io.*;
import java.net.*;
import javax.imageio.*;
import javax.swing.*;

        BufferedImage original = ImageIO.read(url);
        BufferedImage index = convertType(original, BufferedImage.TYPE_BYTE_INDEXED);
        JPanel p = new JPanel(new GridLayout(2,4));
        addToPanel(p, original, "original image");
        addToPanel(p, index, "indexed version");
        float[] scales = {1f, 1.1f, 1.2f, 1.3f, 1.3f, 1.3f};
        float[] offsets = {48, 32, 16, 0, 16, 32};
        for(int i=0; i<scales.length; ++i) {
            float s = scales;
float o = offsets[i];
addToPanel(p, rescale(index, s, o), "scale=" + s + ", offset="+o);
JFrame f = new JFrame("");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setContentPane(p);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
public static BufferedImage convertType(BufferedImage image, int type) {
if (image.getType() == type)
return image;
BufferedImage result = new BufferedImage(image.getWidth(), image.getHeight(), type);
Graphics2D g = result.createGraphics();
g.drawRenderedImage(image, null);
g.dispose();
return result;
static void addToPanel(JPanel p, BufferedImage image, String title) {
JLabel label = new JLabel(new ImageIcon(image));
label.setBorder(BorderFactory.createTitledBorder(title));
p.add(label);
public static IndexColorModel rescale(IndexColorModel icm, float scaleFactor, float offset) {
int size = icm.getMapSize();
byte[] reds=new byte[size], greens=new byte[size], blues=new byte[size], alphas=new byte[size];
icm.getReds(reds);
icm.getGreens(greens);
icm.getBlues(blues);
icm.getAlphas(alphas);
rescale(reds, scaleFactor, offset);

int newComp = Math.round(comp*scaleFactor+offset);
if (newComp < 0)
newComp = 0;
else if (newComp > 255)
newComp = 255;
comps[i] = (byte) newComp;

Blending 32-bit images into panorama clips brightness in CC (Windows)

Hi all,
I'm running Photoshop CC on Windows and am trying to stitch a HDR panorama. I have several 32-bit HDRI images, and I can open them individually and see that the full range of brightness is present by reducing the exposure and seeing the detail come up in the bright areas.
However when I try to run them through Photomerge, I end up with an image that has the brightness clipped - reducing the exposure no longer brings out the highlights in the bright areas.
The culprit seems to be the auto-blending part of the process.
How can I blend 32-bit images to end up with a panorama that has the same dynamic range as the original images? There doesn't seem to be much point having panorama support for 32-bit images if it clips the dynamic range. Am I doing something wrong?
Thanks in advance
-Matthew

It's been out for months.
You're using CC, not CC 2014 -- it may already be installed, and you're just launching the wrong version.

Brightness / contrast settings on color -RGB64 images

Hello everybody,
I have some problem displaying RGB64. Is there any possibiliy to set the constrast / the brightness displaying the data? I know there is some solution for grayscale images and RGB32 images but I didn't found any applicable for RGB64. May somebody has a solution?
I have alos some trouble to convert RGB64 to RGB32 images.
Best regard
Joe

Hi Joe16,
This could help:

http://digital.ni.com/public.nsf/websearch/10C8CFADB37710E786256AE300782419?OpenDocument
The RGB32 images, uses 8 bits for every color planes, so I asume that the RGB64, uses 16bits for every color plane. Check the NI Vision Concepts.
http://digital.ni.com/manuals.nsf/websearch/E1F8EB3E2E28AE34862570AC005CC736
You can configure the the Image Indicator, to configure the display of these 16 bit images, in the Concepts Manual, you can see there diferent methods.
Let me know how it goes.

Image / Adjustments: Brightness/Contrast. Why is it crap now?

Ever since we got CS3, I have to hit the "Legacy" button in the Brightness/Contrast to get decent results. I just tried again WITHOUT using the Legacy button to enhance a scan a little. I brightened it up a few notches and then dragged the contrast bar and NOTHING happened. Whats that about? I hit the Legacy button and do my adjustments and it works as it should. Am I missing something?

How can I apply Brightness, Contrast, Saturation, etc on an color Image or Picture?

I am using IMAQ to open an existing color jpeg file, and perform operations on it. I would like to be able to change the brightness, contrast, saturation, etc. similarly to what can be done to an IMAQ Session via a property node. I've seen examples for grayscale, but not for color? Anyone have ideas / examples?
Thanks,
Tim

I found it -- IMAQ ColorBCGLookup.vi if others are interested.

Exposure vs. Levels vs. Brightness/Contrast Adjustment Layers?

I have some photos that are a bit underexposed and I'm trying to brighten them up a bit and I made a Levels adjustment layer and also experimented with the Exposure adjustment layer. Are these essentially doing the same thing OR are there reasons to have a Levels adjustment layer along with an exposure one and a Brightness/Contrast one?
Thanks in advance.

The Exposure adjustment in Photoshop is primarily meant to correct tonal values of High Dynamic Range images, which are 32 bits. This command makes tonal adjustments using a linear color space or gamma instead of your image’s color space. You can use it on 8 bit or 16 bit images too, but the adjustments may seem rather drastic.
When rescuing poorly exposed 8 bit or 16 bit images, I prefer Levels or Curves because you have greater control. Brightness/Contrast, isn't something I use much.

Using Labview to save image from PCO camera(12 bit images)

Hello,
I have labview 8.5 version in my Winxp. I have PCO camera (pixelfly). So far I know that it saves 12 bit images. I used normal save pattern of labviewas png,tiff or jpeg. As .pngit saves the images as 32 bit and as bmp it takes 8 bit images. But the picture quality is not good. I used IMAQ to take single picture and to save it I used IMAQ Write File 2. I used the following mechanism.
1) IMAQ ImageTo Array--> To unsigned word integer--->IMAQ ArrayToImage--->IMAQ Write File 2---> save it as .png file.
Please inform where I made the problem. Why the picture is not as like as 12 bit images of PCO Camera.
Thanks,
Stuttgart University,Germany.

IMAQ Create.vi supports Grayscale(I16) and RGB (U64). Both should be suitable for 12Bit Greyscale.
Documentation of "IMAG Write File 2.vi" says:
IMAQ Write TIFF File 2
Writes an image to a file in TIFF format.
Note 16-bit monochrome images and 64-bit RGB images are nonstandard extensions of the TIFF standard. Most third-party applications cannot read 16-bit monochrome or 64-bit RGB TIFF files. For compatibility with most applications, write 16-bit monochrome images or 64-bit RGB images into PNG files.

Image Brightness Changes When Authoring DVDs

Hello,
To encode footage I export 720 24p footage from FCP as a Quicktime .mov using Microcosm then encode in Compressor using the standard Best Quality, 16:9, SD setting. The Quicktime .mov and the encoded .m2v file plays with the same image brightness and contrast as does the original footage in the FCP timeline, but once I author it in Studio Pro it consistenly looks lighter and consequently washed out when played back on the same monitor from the DVD. It also ends up looking lighter when played on a TV than programs from a typical rental DVD movie.
I set up my 23" Cine display carefully with with Apple's advanced profiling software, and images and color bars match footage displayed on my Sony PVM-14M that has been set up with color bars through a decklink card.
Can anyone offer advice about why this may be happening? So far my only fix is to arbitrarely change image brightness when encoding with Compressor. Is there some change I should be making in FCP to go from 720 24p HD footage to SD encodes?
Thanks,
Drew Harty
G5 dual 1.8 Mac OS X (10.4.9)

I have read on various forums that people are getting better encodes from HD footage by exporting to a Quicktime file before encoding. Several people have complained about the results exporting directly to Compressor. I take it you haven't found this to be a problem?

Understanding 32 bits image mode

Hi
i'm developping a plugin in which higher image quality means higher sound quality.
though when i'm in mode 32 bits, colors don't behave the same way as in 8 bits or 16 bits.
for example, in 8 bits i have
R = 128;
g = 255;
b = 128;
it will not be the same color as in 32 bits:
R = 0.5;
G = 1;
B = 0.5;
(in 32 bits, is it much brighter)
how come ?
how do i do to use 32 bits mode with the same color scheme as in 8 or 16 bits?
thanks
Jeff

thank you
8 bits and 16 bits images have a gamma 1.0, this is in 32 bits that the gamma is higher.
How do i set gamma = 1 for 32 bits images? I want 8, 16 and 32 bits images behave the same.
thanks
Jeff

Difference in video brightness/contrast across viewer applications

I am using FCP->Color>FCP roundtrip to grade Red footage. After I grade the clips in Color and send them back to FCP, I see a difference in brightness/contrast of the graded clips when playing in FCP. And when I export the final output to quicktime and play it in quicktime player, I see further difference in brightness and contrast. Essentially the clips appear darker when played in QT player. Now I am confused as to which application is showing the correct brightness/gamma level? Is there a way to make all the applications play the video at same/true brightness/gamma? Any insights would be highly appreciate. Thanks!

There is a distinction between PCIe-based GPUs and I/O cards that you have to be aware of. COLOR's user interface, render/scopes and output are split between the two. A graphics processor handles the user interface (PCIe is better, application won't run on on-board integrated or AGP), and actual grade values for judgement are based on a PCIe HD-SDI I/O card like AJA Kona3, or Blackmagic (Intensity?) which are NOT graphics cards, they are video interfaces.
For GPUs, if the application is running, that's a good indicator. However, preferred cards have been evolving over the past 5 years. My first system was configured with a Quadro 4500FX which was a total waste of money. I deliberately chose an ATI X1900XT for the next tower, which was a significant improvement. My third MacPro is running fine with the default ATI 2600HD, which is as plain vanilla as you can get. Some users report speed advantages with the newer 4870 series, but I fail to see significant differences -- COLOR in its current delivery will never deliver "real-time" preview playback on any card, and it still takes a very long time to render, in comparison with some other grade offerings. Fourth machine, I'm still deciding, but it would be great if Apple got the FX4000 thing happening, and I'll get to that.
Nvidia does suffer from some bit-depth processing issues in that it does not directly support 10-bit codecs, but can be switched into the more intensive "float" mode. It also has some other transient issues.
Looking outside Apple COLOR, consider that Blackmagic Resolve ("DaVinci") is predicated entirely on nVidia's CUDA-processing technology and is restricted to implementation on 2 or 3 very specific cards, as opposed to the FCP-centred, but ATI/AJA-leaning Apple solution, which, although somewhat restricted, is 90% more likely to run on almost anything PCIe that you can stick into a MacPro. However, the color science and cross-platform (AVID support, for example) that DaVinci offers makes it very tempting, and that's why I'm paying a lot more attention to nVidia these days.
If you are looking for HDSDI PCIe cards, then AJA, with IO, Kona3, and so on definitely has the edge and can extend capabilities up to and beyond 2K processing, but many users select other solutions that suit their individual needs -- not everyone delivers theatrical Digital Cinema or needs to.
