2d5e3b57ea Fix cppcheck reports warnings: 
(performance) Possible inefficient checking for 'lmap' emptiness
(warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it?
(style) Array index '<xxx>' is used before limits check

c762da9893 Fix SymmColumnSmallVec_32s16s SSE code 
Specifically, in general antisymmetric case src[-1] (S0) should be
subtracted from from src[1] (S2), and not the opposite.

41afe54696 Fix determining bounding box of the edge collection in FillEdgeCollection(). 
There is necessary to account also x-coordinate of the end of the edge when determining bounding box of the edge collection.

e88bf2bc30 Updated Documentation (HoughCircles) 
Rewrite the note on HoughCircles documentation to make it more clear

Add note to clarify that the output vector of found circles is sorted by
descending order of centres accumulator values.

Also delete reductant lines on the HoughCircles documentation.

Added comments to hough circles function.

Added comments to icvhoughgradient

Misalignment in line 1183 corrected

a7757b0eb6 Fix anchor for small symmetrical column filters. 
In the unoptimized version of small symmetrical column filters, when we
try to detect if the kernel, ky, is equal to [1;2;1] or [1;-2;1] we
should take into consideration that the anchor points in the middle
element.
