is it possible to retrace back to the values of intensities that have been captured by the digital camera from the image's RGB values?
One can use matlab to know the RGB values's data for all the pixels. But the camera captures the data by measuring intensities at each photodiode. These values are such that they correspond to one out ...
I know this almost touches some other questions already asked here, but it's actually aligned a bit different. This is not about DNG vs RAW, rather just about the demosaicing step in the conversion. ...
Is there a relatively easy to use tool that will allow me to demosaic some raw data stored in a TIFF file (not a standard raw file such as DNG, NEF, etc.), assuming a Bayer pattern? The TIFF contains ...
What is the simplest way to access the data in a raw file before demosaicing and write it to a more widely supported file format (e.g. 16 bit TIFF)? I'm looking to obtain a single channel image where ...
If I give Rawtherapee or Darktable a raw image, they will automatically transform the raw image using their internal pipeline to an output image. Let's say I have designed a new demosaicing ...
I am a little familiar with tools like dcraw or libraw. I know that we can give one RAW image to each of these tools, and they will give us output image, which is gone through a pipeline procedure: ...
I understand the purpose of the anti-aliasing (AA) filter is to prevent moire. When digital cameras first emerged an AA filter was necessary to creat enough blur to prevent moire patterns. At that ...
Given that the main purpose of demosaicing is to recover colour as accurately as possible, would there be any advantage to a "black and white only" demosaic algorithm? That is, instead of first ...
Fujifilm has an innovative new sensor layout for the just-released X Pro-1 camera, which they say is "inspired by the natural random arrangement of the fine grains of silver halide in film": Since ...
Bayer sensors use a pattern of red, green, and blue pixels, and merge those together into a final color image, with one pixel for every single color sensor. This could be done through a "naive" ...
