Description

This commit implements Hessian corner detector, with response function being the same as in Harris.

Compatibility

Anything compatible with Boost 1.70

References

https://en.wikipedia.org/wiki/Hessian_matrix

Tasklist

  • Implement Hessian corner detection algorithm
  • Add inline docs
  • Add larger docs to explain the algorithm better will be covered by another PR
  • Add test cases
  • Ensure all CI builds pass
  • Review and approve

@simmplecoder I know close to nothing about Hessian detector. I can only offer a nitpicking C++ guidelines/style review. Do you still wish to have one?

@mloskot , yes, any constructive criticism is welcome! (Boost guidelines, GIL guidelines, any other concerns).

This commit partially implements
Hessian corner detector, but only
uses determinant as Hessian response
This commit complements last one
by summing in a window and applying
det - k * trace * trace formula to
final Hessian response
This commit adds docs to new functions,
and makes function and variable names
align with docs to not confuse readers
A-KAZE uses only determinant in it's
response, and since for now Hessian
is only a mean to advance A-KAZE
implementation, response function is
adjusted to use only determinant
This commit adds an s at the end of
function name to make it uniform with
another detector, and adds a simple
test for sanity check
dx and similar naming seems to be
confusing, improved documentation
to explain the naming convention
Mostly changes to constness and
integral types, with small cosmetic
changes mixed in
Fixes typo in call for Hessian and
addresses a review comment about
replacing multiple exact indexing
calls to one with a reference
Add literature reference to luminosity
computation, and perform some cosmetic
changes.
