Convert Bayer pattern encoded image to truecolor image
RGB = demosaic(I, sensorAlignment)
RGB = demosaic(I, sensorAlignment) converts
a Bayer pattern encoded image to a truecolor image using gradient-corrected
I is an M-by-N array of intensity
values that are Bayer pattern encoded.
I must have
at least 5 rows and 5 columns.
A Bayer filter mosaic, or color filter array, refers to the
arrangement of color filters that let each sensor in a single-sensor
digital camera record only red, green, or blue data. The patterns
emphasize the number of green sensors to mimic the human eye's greater
sensitivity to green light. The
uses interpolation to convert the two-dimensional Bayer-encoded image
into the truecolor image,
RGB, which is an M-by-N-by-3
sensorAlignment is one of the following text
strings that specifies the Bayer pattern. Each string represents the
order of the red, green, and blue sensors by describing the four pixels
in the upper-left corner of the image (left-to-right, top-to-bottom).
|Value||2–by-2 Sensor Alignment|
I can be
and it must be real.
RGB has the same class as
Convert a Bayer pattern encoded image that was photographed by a camera with a sensor alignment of
