develop.raw {adimpro}

Create a color image from RAW image data.

Description

The function generates a color image from RAW image data.

Usage

develop.raw(object, method = "BILINEAR", wb = c(1, 1, 1), maxrange= TRUE, compress = TRUE)

Arguments

object

An object of class "adimpro" containing RAW image data, e.g. created by function read.raw. Such an object is characterized by object$type=="RAW".

method

Method to fill missing color values. Currently implemented are method="HALF" (reduce image size by factor of 2), method="FULL" (use color from neighbor within (2x2) Bayer mask)), method="BILINEAR" (bilinear interpolation), method="Median4" and method="Median16", the latter two being based on L1-MM over shifted Bayer masks. method="Median16" delivers much smoother results, but is considerably slower then the other methods.

wb

numerical vector of length 3 containing multiplicative factors for the three color channels.

maxrange

If TRUE increase range of values to maximum.

compress

logical, determines if image data are stored as raw.

Details

RAW image data usually contain only one color value at each pixel, with colors arranged in a so called Bayer mask. Converting RAW images into color images requires to fill the missing entries in the color channels.

Value

object of class "adimpro" containing the image.

Note

The function requires dcraw to be installed.
