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 ...
What are deflicker algorithms used to deflicker stills that should be composed to a timelapse movie? (Flickering caused by shutterspeed adjustments in sunset/sunrise shots...)
Nowadays some advanced cameras have the feature of "smile shot" without the photographer pressing the shutter. How do the cameras achieve this? How does it recognise the smile?
I'm not talking about drawing smooth curves here, but rather the curves tool used for adjusting color levels. An illustration will be worth a thousand words, here. This is an adjustment in Gimp: ...
I have the following formula: DR=(1.4L_Sat G_i)/N_D where DR is the dynamic range; L_sat is the luminance at the “margin level”，70.1% of the maximum recordable （saturation）luminance（yes，L_sat is ...
I'm a developer who wants to figure out when a filter would look good applied to a given image. For example, I have sepia, solarisation and pencil filters. Okay, the perception will be very ...
I'm very interested in learning about algorithms in photography (in particular processing photos). In addition to algorithms, I'm interested in learning about photo formats (probably RAW and jpeg the ...
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" ...
