* <p>
* Notes:
* <ol>
* <li>The Otsu method finds a single global threshold for an image. This
* function allows a locally adapted threshold to be found for each tile
* into which the image is broken up.
* <li>The array of threshold values, one for each tile, constitutes a
* highly downscaled image. This array is optionally smoothed using a
* convolution. The full width and height of the convolution kernel are (2 *
* smoothX + 1) and (2 * smoothY + 1).
* <li>The minimum tile dimension allowed is 16. If such small tiles are
* used, it is recommended to use smoothing, because without smoothing, each
* small tile determines the splitting threshold independently. A tile that
* is entirely in the image bg will then hallucinate fg, resulting in a very
* noisy binarization. The smoothing should be large enough that no tile is
* only influenced by one type (fg or bg) of pixels, because it will force a
* split of its pixels.
* <li>To get a single global threshold for the entire image, use input
* values of sizeX and sizeY that are larger than the image. For this
* situation, the smoothing parameters are ignored.
* <li>The threshold values partition the image pixels into two classes: one
* whose values are less than the threshold and another whose values are
* greater than or equal to the threshold. This is the same use of
* 'threshold' as in pixThresholdToBinary().
* <li>The scorefract is the fraction of the maximum Otsu score, which is
* used to determine the range over which the histogram minimum is searched.
* See numaSplitDistribution() for details on the underlying method of
* choosing a threshold.
* <li>This uses enables a modified version of the Otsu criterion for
* splitting the distribution of pixels in each tile into a fg and bg part.
* The modification consists of searching for a minimum in the histogram
* over a range of pixel values where the Otsu score is within a defined
* fraction, scoreFraction, of the max score. To get the original Otsu
* algorithm, set scoreFraction == 0.

* <li> For nx == ny == 1, this defaults to pixSauvolaBinarize().
* <li> Why a tiled version?
* (a) Because the mean value accumulator is a uint32, overflow
* can occur for an image with more than 16M pixels.
* (b) The mean value accumulator array for 16M pixels is 64 MB.
* The mean square accumulator array for 16M pixels is 128 MB.
* Using tiles reduces the size of these arrays.
* (c) Each tile can be processed independently, in parallel,
* on a multicore processor.
* <li> The Sauvola threshold is determined from the formula:
* t = m * (1 - k * (1 - s / 128))
* where:
* t = local threshold
* m = local mean
* k = @factor (>= 0) [ typ. 0.35 ]
* s = local standard deviation, which is maximized at
* 127.5 when half the samples are 0 and half are 255.
* <li> The basic idea of Niblack and Sauvola binarization is that

## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.

## Some versions of gcc put a space before the `:'. On the theory
## that the space means something, we add a space to the output as

/*
* adaptmap_dark.c
*
* Demonstrates the effect of the fg threshold on adaptive mapping
* and cleaning for images with dark and variable background.
*
* The example pages are text and image. For both, because the
* background is both dark and variable, using a lower threshold
* gives much better results.
*
* For text, cleaning the background to white after adaptively
* remapping to make the background uniform is preferable.
* The final cleaning step uses pixGammaTRC() where the white value
* (here, 180) is set below the remapped gray value (here, 200).
*
* For the image, however, it is best to stop after remapping
* the background. Going further and moving pixels near the
* background color to white removes the details in the lighter
* regions of the image. In practice, parts of a scanned page
* that are image (as opposed to text) don't necessarily have
* background pixels that should be white. These regions can be
* protected by masks from operations, such as pixGammaTRC(),
* where the white value is less than 255.

* binarize_set.c
*
* Does 5 different types of binarization for the contest.
*
* Method 1. Using local background normalization, followed by
* a global threshold.
* Method 2. Using local background normalization, followed by
* Otsu on the result to get a global threshold that
* can be applied to the normalized image.
* Method 3. Using local background normalization with two different
* thresholds. For the part of the image near the text,
* a high threshold can be chosen, to render the text
* fully in black. For the rest of the image,
* much of which is background, use a threshold based on
* the Otsu global value of the original image.
* Method 4. Background normalization followed by Sauvola binarization.
* Method 5. Contrast normalization followed by background normalization
* and thresholding.
*
* The first 3 were submitted to a binarization contest associated
* with ICDAR in 2009. The 4th and 5th work better for difficult
* images, such as w91frag.jpg.

* binmorph1_reg.c
*
* This is a thorough regression test of different methods for
* doing binary morphology. It should always be run if changes
* are made to the low-level morphology code.
*
* Some things to note:
*
* (1) We add a white border to guarantee safe closing; i.e., that
* closing is extensive for ASYMMETRIC_MORPH_BC. The separable
* sequence for closing is not safe, so if we didn't add the border
* ab initio, we would get different results for the atomic sequence
* closing (which is safe) and the separable one.
*
* (2) There are no differences in any of the operations:
* rasterop general
* rasterop brick
* morph sequence rasterop brick
* dwa brick
* morph sequence dwa brick
* morph sequence dwa composite brick
* when using ASYMMETRIC_MORPH_BC.
* However, when using SYMMETRIC_MORPH_BC, there are differences
* in two of the safe closing operations. These differences
* are in pix numbers 4 and 5. These differences are
* all due to the fact that for SYMMETRIC_MORPH_BC, we don't need
* to add any borders to get the correct answer. When we do
* add a border of 0 pixels, we naturally get a different result.
*
* (3) The 2-way Sel decomposition functions, implemented with the
* separable brick interface, are tested separately against
* the rasterop brick. See binmorph2_reg.c.

/*
* binmorph3_reg.c
*
* This is a regression test of dwa functions. It should always
* be run if changes are made to the low-level morphology code.
*
* Some things to note:
*
* (1) This compares results for these operations:
* - rasterop brick (non-separable, separable)
* - dwa brick (separable), as implemented in morphdwa.c
* - dwa brick separable, but using lower-level non-separable
* autogen'd code.
*
* (2) See in-line comments for ordinary closing and safe closing.
* The complication is due to the fact that the results differ
* for symmetric and asymmetric b.c., so we must do some
* fine adjustments of the border when implementing using
* the lower-level code directly.
