Improve utilities sending channels, pixels and other GIL objects to
output stream for logging of test errors.
Fix missing namespace qualification in IO tests.
Comment TARGA test case with FIXME that was accidentally
uncommented in cc64bdd1a4
* Implement Sobel and Scharr operators
This commit adds Sobel and Scharr
operators with support for 0th and 1st
degrees with other degrees planned for
later
* Migrate and fix Harris example
Generate Harris entries now uses
signed image view.
The Harris corner detector example
now uses the Scharr filter generator
and convolve_2d to reduce amount
of code needed.
* Fix and migrate Hessian example
The Hessian example now uses signed
image views and uses newly added kernel
generators to compute gradients
* Fix Harris and Hessian tests
The tests broke due to migration to
signed views in algorithms, but tests
were not adjusted
* Fix Jamfile for example/sobel_scharr.cpp
* Cosmetic changes
* Commented out fail tests
* Fixed pixel16 used in image16s
In Harris and Hessian tests, unsigned
pixel values was used to construct
signed image, which was causing
appveyor to error out.
* Reenable failing targets
* Unify kernel generator interface
This commit makes all kernel
generator functions to return kernel_2d
and adapts dependant threshold
function to use the new interface
* Migrate Hessian and Harris tests
Migrate Hessian and Harris tests to new
interface for kernel generators
* Migrate Harris and Hessian examples
Harris and Hessian examples now use
new interface for kernel generation
* Migrate simple_kernels tests
simple_kernels are now using kernel_2d
interface
* Add missing return
Normalized mean generation had missing
return at the end of the function
* Adapt code to namespace move
This commit reacts to kernel_2d,
convolve_2d being moved to
namespace detail
* Implement generation of simple kernels
This commits implements mean and
Gaussian kernel generators,
roughly documents them, and has
tests. But tests for Gaussian have
accuracy problem
* Use difference for testing Gaussian
This commit applies percentage based
difference check on generation of
Gaussian kernels, as exact values are
dependant on platform. The error margin
is set to 5% in this commit
* Remove debugging code
In simple_kernels.cpp, there was
some debugging code, mostly streams
related stuff and commented out code,
which is now removed.
* Address review comments
This commit adds inline to kernel
generator functions, uses
std::ptrdiff_t instead of long int,
resolves some conversion warnings
and does small cosmetic changes
* Remove useless iostream include
There was stray include from debugging
code, now removed
* Use \code and \endcode for formula
This commit applies formatting to
formula of normalized mean
* Change are_equal to is_equal
Change a function name in
simple_kernels.cpp test
* Remove redundant function
In simple_kernels.cpp test there was
a function that was not used at all,
now removed
* Cosmetic changes
Mostly opening brackets moved
