Denoising of RGB

I have an RGB image with little noise, I want to filter.

I want to do this by using the wavelet to Daubechie.

the idea is to break up the image on the R, G, B fields, transformed Wavelet for each, crossing a threshold and then recompose.

My problem at the moment, it is that when I try to do the transformation in Wavelet Daubechie integrated in any table field (R, G or B) I have zeros as a result (the table is not empty).

any ideas on how this should be done?

  • Preview color management issue - glued assigned Adobe RGB image

    I often web elements page layout in InDesign that my composition tool, then copy and paste in Photoshop as a smart object to then generate optimized web images. It's just easier to use photoshop. Problem, it is in the latest versions of Adobe have clogged the engine of anti-aliasing and now when rasterising a PDF file or paste a picture also as a chip oppose any portion of the image of this asset is smoother. You don't really notice that if the image of origin placed in InDesign is say double or more this resolution of the web version of final product, the scale hides the issue. But if they are closer to really see faceting full size occurs. Long story... anyway, I decided to study the implementation overview of Apple as a gateway for the rasterising instead of photoshop. He did a good job on glued assets resampling, but on this point saving and checking in Photoshop, I note that Preview assigned Adobe RGB profile to the processed image. Even if I opened the InDesign PDF and export as image in my size. My color workflow is sRGB. InDesign and Photoshop are two parameters in this way, the image placed in InDesign also has sRGB profile, the PDF has sRGB profile. If I copy / paste between InDesign and Photoshop, they are both aware glued Trump space and warn me if different from that of the target document. I have no idea where Preview becomes Adobe RGB, I don't see its place in the app to change that as a preference, and in any case, it seems very strange to be a defect when most of the people would not use them.

    In the preview, click on the tools bar menu point and scroll to the bottom of the drop-down list to assign the profile

    the next submenu you can click on and select sRGB at the bottom of this list. To save this profile to your image,

    do a "save under" (click on file, press the option/alt key Save As should appear). You can also test under the view menu bar item.

  • No display on screen Z30 - a Portege but HDMI / RGB ports work

    Hello

    I have a laptop of i7 Z30 - A old Portege of 6 months (PT243A-0HW02X) running Windows 7 64 bit and the internal display of 1920 x 1080 screen 13.3 "doesn't work - nothing is displayed on the screen.

    However, I can connect an external monitor via the port of RGB cable or the HDMI port and still use the laptop like that.

    I tried various output F5 toggle function choose Clone, external, Extend, switch display, but nothing works to get back out again to the laptop screen.

    The external option that I see a gray icon to clear color laptop with an X on the screen, and a '1' on another display icon and a window is displayed for "Toshiba Flash Cards" red x error message "Failed to initialize the output Configuration dialog box!". "."

    There is no extra help available to tell me what the problem is.
    When I choose the option to set up output function F5, the 'Internal' line is grayed out so I can't select it.

    Does anyone else have this problem?
    An update of the BIOS might help tell me if there is a hardware problem?
    There is nothing about the display error in the Windows Event Viewer.

    Thank you.

    I'm wrong CPU built in this Z30t-A-123 should be the Intel i7-4510U and this processor supports the Intel HD Graphics 4400.

    The latest graphics card for this Intel graphics driver may be downloaded from the Intel page:
    https://Downloadcenter.Intel.com/

    Here, you will get the list of drivers for the Intel HD 4400

    I recommend you to choose the ZIP package in order to install the driver in Device Manager by using the Advanced installation procedure.

    I guess you need VIDEO driver since I never heard of a RGB driver. The VIDEO (or known as VGA) driver is usually available on the toshiba driver site, so I Don t understand why you need this if you have already downloaded all the drivers available.

  • 1920 x 1080 - RGB - PC is not possible on Toshiba 32L2333DG

    I recently bought a 32L2333DG.

    When I connect the PC to the RGB/PC port I can only get 1366 x 768 maximum resolution. I find nothing on this topic in the user manual. (I tested with another TV and my PC can display 1920 x 1080 with the standard VGA port)

    If I connect the PC using HDMI then I get 1920 x 1080.

    The question is: what should I do to achieve maximum resolution using RGB - PC port?

    I guess this 1366 x 768 is the max resolution of supported using the RGB/PC port

  • Satellite A10: RGB Port is not installed - can not use external display

    Satellite A10 the RGB PORT is not installed & cannot be used as external display. I tried to install the communication or COM 1. interrupt code. What are the possible solutions?

    Hello

    What did you mean by "not installed"?
    Generally, you don't need to install anything. You don't need any drivers for this port 3.
    Windows XP drivers should work properly.

    Please check device manager if there are errors or yellow exclamation points.
    If the problem occurs for a short time, you can try to use the WinXP restore tool.
    This tool will reduce the BONE until the start.

  • Satellite M30x-174: cooler starts denoising when I connect USB mouse

    Hello

    I bought a toshiba satellite m30x-174 a couple of months, and I have a problem with it.
    When the computer is turned on (without the mouse into the usb port), but not ongoing enforcement programs other than windows, it runs nice and quiet, but when I connect to my mouse starts denoising. I think it's the cooler that begins. Then when I remove the mouse stops denoising again. I tried with different mouse, but it doesn't change anything.

    Nothing changes in the windows task manager when the mouse is connected/disconnected.
    Hope you can help me.

    It is very interesting occurrence. I use as external I smile and have him try connect or disconnect. You are absolutely right. In Task Manager there is no change.

    Hello

    under the "major operation" there is the option to record YPbPr or RGB. I understand the difference in the color science, but what is the real life of this effect in the F5?

    I shot a Macbeth color with two settings checker, and there is absolutely no difference visible and measurable.

    So what?

    Thank you!

  • Statistics of the 32-bit image RGB

    Hi friends, I am trying to get an image RGB information. I created a VI in labview to aid vision for this wizard.

    But the problem is that, although it attracts the histogram for all three colors, it displays 'statistics '.

    (i.e. max min value, standard deviation etc.) for the color red and blue, and green also.

    What should I do in order to get statistics for all three colors.

    Best wishes

    Automator

    Hello

    You just drag an express VI, created from Wizard of vision or have you created the VI yourself in the range of vision?

    I suggest to do the latter and use this function:

    If you have problems, doing so after the VI is came with, it will be easier for people to help you

    Hope this helps

  • Open DMX to control the RGB LED lights

    For a demonstration, I would like to order by DMX RGB LED lights.

    I have a compatible open USB2DMX cable DMX (made by JMS but similar to ENTTEC) based on FTDI interface.
